Included Markers
16 markersThe complete metabolic panel measures a wide range of markers related to organ function and metabolic balance. It includes electrolytes, kidney and liver markers, glucose regulation, and protein levels, providing a detailed look at how your body is processing and regulating its internal environment.
Why this test?
Your body maintains a careful balance of electrolytes, sugars, proteins, and waste products. Shifts in these values can occur gradually and may not cause noticeable symptoms in the early stages. A metabolic panel can help identify changes in kidney filtration, liver processing, blood sugar regulation, or electrolyte levels before they become apparent through symptoms.
Who is this test for?
This test may be relevant for:
- People who want a detailed view of their metabolic health
- Those who are monitoring kidney or liver function
- Anyone interested in their blood sugar regulation
- People taking medications that may affect electrolyte or organ function
- Those who want to understand how their body is processing nutrients and waste
What is tested?
This panel includes the following markers:
- Albumin: a protein produced by the liver, involved in fluid balance
- ALP (Alkaline Phosphatase): an enzyme found in the liver and bones
- ALT and AST: liver enzymes that may indicate liver cell activity
- Bicarbonate: helps regulate the body's acid-base balance
- Bilirubin (Total): a waste product from red blood cell breakdown, processed by the liver
- Calcium: involved in bone health, muscle function, and nerve signalling
- Chloride: an electrolyte that helps maintain fluid balance
- Creatinine and eGFR: reflect kidney filtration capacity
- Glucose (Fasting): a measure of blood sugar at the time of the test
- HbA1c: reflects average blood sugar levels over 2 to 3 months
- Potassium: an electrolyte involved in heart and muscle function
- Sodium: an electrolyte involved in fluid and blood pressure regulation
- Total Protein: a combined measure of albumin and globulin in the blood
- Urea (BUN): a waste product filtered by the kidneys
What can this test tell you?
The markers in this panel cover several interconnected systems. Creatinine and eGFR can reflect kidney filtration capacity, while urea provides additional context about protein metabolism and kidney function. Liver enzymes such as ALT and AST may indicate how actively liver cells are working. Electrolyte levels can point to fluid balance and hydration status.
Glucose and HbA1c together provide a picture of both short-term and longer-term blood sugar regulation. Protein markers may reflect nutritional status and liver production capacity. The results are most meaningful when interpreted as a whole rather than in isolation.
How is the sample collected?
This test uses a blood sample collected at a certified sample point (afnamepunt). With over 750 partner locations across the Netherlands, you can select a location that works for you. You can book online or walk in. A trained phlebotomist performs the blood draw, and results are typically available within a few working days.
When is this test useful?
This test may be useful when:
- You want a detailed overview of your metabolic and organ function
- You are taking medications that may affect your liver, kidneys, or electrolytes
- You have a family history of kidney disease, liver conditions, or diabetes
- You want to monitor how your body responds to dietary or lifestyle changes
What do the results mean?
Each marker is shown alongside a reference range. Values within range generally suggest normal function for that parameter. When a value falls outside the range, it may point to an area worth discussing with a healthcare provider. For example, an elevated creatinine with a reduced eGFR may suggest altered kidney filtration, while elevated liver enzymes may reflect increased liver cell activity.
Individual values can fluctuate based on hydration, diet, and timing. A healthcare provider can help interpret the results in the context of your overall health.
Preparation
Fasting for 8 to 12 hours before your appointment is required for accurate glucose results. Water is allowed during the fasting period. Morning collection is recommended for the most consistent readings. Avoid strenuous exercise in the 24 hours before the test.
What happens after the results?
Your results are typically available within a few working days. The report includes your measured values, reference ranges, and plain-language explanations for each marker. If any values fall outside the expected range, this is clearly indicated. We recommend reviewing the results with a healthcare provider, who can assess them in the context of your health history and advise on any follow-up.

What We Test
This health panel includes 16 biomarkers to give you a comprehensive picture of your health.
Bicarbonate is an electrolyte that helps maintain the body's acid-base balance. It acts as a buffer in the blood, neutralising excess acids and helping to keep your pH within a healthy range.
Learn moreCalcium is the most abundant mineral in the body, essential for strong bones and teeth, muscle contraction, nerve signalling, and blood clotting. Most calcium is stored in bones and teeth, with a small amount circulating in the blood.
Learn moreChloride is an essential electrolyte that helps maintain fluid balance, blood pressure, and the body's acid-base equilibrium. It works closely with sodium and potassium to regulate these vital functions.
Learn morePotassium is an essential mineral and electrolyte that plays a crucial role in the functioning of your muscles, nerves, and heart rhythm. Your body regulates potassium concentration precisely — even small deviations can have serious consequences, particularly for the heart. Potassium levels are influenced by kidney function, diet, fluid balance, and medication use. It is routinely included in an electrolyte panel.
Learn moreSodium is a vital electrolyte that regulates fluid balance, blood pressure, and nerve and muscle function. It is the primary cation in extracellular fluid and is closely regulated by the kidneys.
Learn moreGlucose is the primary energy source for your body. Your fasting glucose level (measured after at least eight hours of fasting) indicates how well your body can regulate blood sugar. An elevated fasting glucose can indicate prediabetes or type 2 diabetes, while a low value (hypoglycaemia) can cause symptoms such as trembling, sweating, and difficulty concentrating.
Learn moreHbA1c (glycated haemoglobin) reflects your average blood sugar levels over the past 2-3 months. It is the gold standard for long-term blood sugar monitoring and diabetes management.
Learn moreAlbumin is the most abundant protein in the blood, produced by the liver. It maintains fluid balance, transports hormones and nutrients, and serves as an indicator of liver and kidney function.
Learn moreAlkaline Phosphatase (ALP) is an enzyme found in the liver, bones, kidneys, and digestive system. ALP levels can help evaluate liver health, bone disorders, and bile duct function.
Learn moreALT, also known as ALAT or GPT, is an enzyme found primarily in the liver. When liver cells become damaged, ALT is released into the bloodstream. An elevated ALT level is therefore one of the earliest signals of liver stress or damage. It can indicate fatty liver disease, hepatitis, medication that burdens the liver, or excessive alcohol use — but also something temporary such as intense physical exercise.
Learn moreAST (aspartate aminotransferase) is an enzyme found in the liver, heart, and muscle cells. Elevated levels may indicate liver damage, but because AST is present in multiple tissues, results are best interpreted alongside other liver markers such as ALT.
Learn moreTotal bilirubin measures the combined amount of direct and indirect bilirubin in your blood. Bilirubin is a waste product formed during the normal breakdown of red blood cells, and elevated levels may indicate liver disease, bile duct problems, or increased red blood cell destruction.
Learn moreBUN (blood urea nitrogen) measures the amount of urea nitrogen in your blood, a waste product formed when the body breaks down protein. It is primarily used to evaluate kidney function and can be influenced by diet, hydration status, and liver health.
Learn moreCreatinine is a waste product of creatine, a substance your muscles use for energy supply. The kidneys filter creatinine from your blood and excrete it through urine. When the kidneys function less well, creatinine accumulates in the blood. The creatinine level is therefore one of the most important markers for assessing kidney function. It is often measured alongside eGFR, which gives a more precise estimate of how well your kidneys are working.
Learn moreThe eGFR (estimated glomerular filtration rate) estimates how much blood your kidneys filter per minute. It is calculated from your creatinine level, age, sex, and ethnicity using the CKD-EPI formula. eGFR is more accurate than creatinine alone and is used to classify kidney function loss into stages. An eGFR above 90 ml/min is normal; below 60 ml/min indicates clinically relevant kidney function reduction.
Learn moreTotal protein measures the combined amount of albumin and globulins in your blood. These proteins play essential roles in maintaining fluid balance, fighting infections, transporting substances, and supporting tissue repair.
Learn moreBicarbonate
MineralsBicarbonate is an electrolyte that helps maintain the body's acid-base balance. It acts as a buffer in the blood, neutralising excess acids and helping to keep your pH within a healthy range.
Proper bicarbonate levels are essential for maintaining blood pH. Imbalances may indicate respiratory or metabolic conditions and can affect organ function. Consult your healthcare provider for interpretation of your results.
Calcium
MineralsCalcium is the most abundant mineral in the body, essential for strong bones and teeth, muscle contraction, nerve signalling, and blood clotting. Most calcium is stored in bones and teeth, with a small amount circulating in the blood.
Calcium balance is critical for bone health, heart function, and muscle contraction. Abnormal levels may be associated with bone disorders, parathyroid conditions, or kidney problems. Consult your healthcare provider for personalised advice.
Chloride
MineralsChloride is an essential electrolyte that helps maintain fluid balance, blood pressure, and the body's acid-base equilibrium. It works closely with sodium and potassium to regulate these vital functions.
Chloride imbalances can indicate dehydration, kidney disease, or acid-base disturbances. Maintaining proper chloride levels is important for overall metabolic health. Consult your healthcare provider for result interpretation.
Potassium
MineralsPotassium is an essential mineral and electrolyte that plays a crucial role in the functioning of your muscles, nerves, and heart rhythm. Your body regulates potassium concentration precisely — even small deviations can have serious consequences, particularly for the heart. Potassium levels are influenced by kidney function, diet, fluid balance, and medication use. It is routinely included in an electrolyte panel.
Potassium is directly linked to the electrical conductivity of the heart. Both too high and too low potassium can cause heart rhythm disorders that in severe cases can be life-threatening. This makes potassium one of the most critical blood values. With certain medications, potassium monitoring is essential. ACE inhibitors and ARBs (commonly used blood pressure medications) can raise potassium. Diuretics such as furosemide and hydrochlorothiazide lower potassium. With combined use, periodic monitoring is necessary.
Sodium
MineralsSodium is a vital electrolyte that regulates fluid balance, blood pressure, and nerve and muscle function. It is the primary cation in extracellular fluid and is closely regulated by the kidneys.
Sodium balance is essential for proper nerve transmission, muscle contraction, and blood pressure regulation. Significant imbalances can affect brain function and require medical attention. Consult your healthcare provider for guidance.
Glucose (Fasting)
MetabolicGlucose is the primary energy source for your body. Your fasting glucose level (measured after at least eight hours of fasting) indicates how well your body can regulate blood sugar. An elevated fasting glucose can indicate prediabetes or type 2 diabetes, while a low value (hypoglycaemia) can cause symptoms such as trembling, sweating, and difficulty concentrating.
Type 2 diabetes affects more than one million people in the Netherlands, and an estimated 1.1 million more have prediabetes without knowing it. Untreated, diabetes significantly increases the risk of cardiovascular disease, kidney damage, eye problems, and nerve damage. Prediabetes is a reversible stage. With lifestyle adjustments — weight loss, more exercise, less sugar and processed carbohydrates — more than half of people with prediabetes can prevent developing diabetes. This makes early detection through a fasting glucose test or HbA1c very valuable.
HbA1c (Glycated Hemoglobin)
MetabolicHbA1c (glycated haemoglobin) reflects your average blood sugar levels over the past 2-3 months. It is the gold standard for long-term blood sugar monitoring and diabetes management.
HbA1c provides a long-term view of blood sugar control, unlike fasting glucose which reflects a single point in time. It is essential for diabetes diagnosis and management. Consult your healthcare provider.
Albumin
LiverAlbumin is the most abundant protein in the blood, produced by the liver. It maintains fluid balance, transports hormones and nutrients, and serves as an indicator of liver and kidney function.
Albumin is important for maintaining blood volume, transporting substances, and reflecting overall health status. Low levels may indicate liver disease, kidney disease, or malnutrition. Consult your healthcare provider.
ALP (Alkaline Phosphatase)
LiverAlkaline Phosphatase (ALP) is an enzyme found in the liver, bones, kidneys, and digestive system. ALP levels can help evaluate liver health, bone disorders, and bile duct function.
ALP is a useful screening marker for liver and bone conditions. Elevated levels may indicate bile duct obstruction, liver disease, or bone disorders. Consult your healthcare provider for interpretation.
ALT (Alanine Aminotransferase)
LiverALT, also known as ALAT or GPT, is an enzyme found primarily in the liver. When liver cells become damaged, ALT is released into the bloodstream. An elevated ALT level is therefore one of the earliest signals of liver stress or damage. It can indicate fatty liver disease, hepatitis, medication that burdens the liver, or excessive alcohol use — but also something temporary such as intense physical exercise.
ALT is one of the most commonly used markers to detect liver stress or damage early. The liver has a large regenerative capacity and often only produces symptoms when damage is already advanced. ALT can be elevated before you notice anything. Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronically mildly elevated ALT in Western countries. An estimated 25% of adults have some degree of fatty liver, often without knowing it. ALT monitoring can reveal this early, allowing lifestyle adjustments to prevent further damage. With alcohol use, the ALT/AST ratio provides additional information. An AST/ALT ratio above 2 is consistent with alcohol-related liver damage, while in fatty liver disease, ALT is typically higher than AST. Medications such as paracetamol (at high doses), statins, and certain antibiotics can also elevate ALT.
AST (Aspartate Aminotransferase)
LiverAST (aspartate aminotransferase) is an enzyme found in the liver, heart, and muscle cells. Elevated levels may indicate liver damage, but because AST is present in multiple tissues, results are best interpreted alongside other liver markers such as ALT.
AST levels provide important information about the health of your liver, heart, and muscles. Elevated levels may be associated with conditions such as hepatitis, cirrhosis, heart attack, or muscle injury. When evaluated alongside ALT, the AST:ALT ratio can help your healthcare provider identify the underlying cause of liver enzyme elevation. An AST:ALT ratio greater than 2:1, for instance, may suggest alcohol-related liver damage.
Bilirubin (Total)
LiverTotal bilirubin measures the combined amount of direct and indirect bilirubin in your blood. Bilirubin is a waste product formed during the normal breakdown of red blood cells, and elevated levels may indicate liver disease, bile duct problems, or increased red blood cell destruction.
Total bilirubin is a fundamental marker for assessing liver function and diagnosing the cause of jaundice. By comparing total bilirubin with direct bilirubin, healthcare providers can determine whether elevation is due to liver disease, bile duct obstruction, or haemolysis. Mild elevations may occur in common and generally harmless conditions such as Gilbert syndrome, which affects approximately 5-10% of the population. However, significant elevations warrant further investigation to rule out serious underlying conditions.
Urea (BUN)
KidneyBUN (blood urea nitrogen) measures the amount of urea nitrogen in your blood, a waste product formed when the body breaks down protein. It is primarily used to evaluate kidney function and can be influenced by diet, hydration status, and liver health.
BUN is a valuable marker for assessing how effectively your kidneys are filtering waste from your blood. Elevated levels may indicate that the kidneys are not functioning optimally, which can be associated with dehydration, kidney disease, or other underlying conditions. Monitoring BUN alongside other kidney markers such as creatinine and eGFR provides a more comprehensive picture of renal health and helps detect potential problems early.
Creatinine
KidneyCreatinine is a waste product of creatine, a substance your muscles use for energy supply. The kidneys filter creatinine from your blood and excrete it through urine. When the kidneys function less well, creatinine accumulates in the blood. The creatinine level is therefore one of the most important markers for assessing kidney function. It is often measured alongside eGFR, which gives a more precise estimate of how well your kidneys are working.
Chronic kidney damage often progresses silently and rarely causes symptoms in early stages. Your kidneys can lose up to 50% of their function before you notice anything. Creatinine and eGFR are the standard markers for early detection. In diabetes and high blood pressure — the two leading causes of chronic kidney damage — periodic creatinine monitoring is part of clinical guidelines. Kidney function monitoring is also recommended during long-term use of NSAIDs (painkillers such as ibuprofen and diclofenac), ACE inhibitors, or certain antibiotics. An elevated creatinine does not always indicate kidney damage. In people with high muscle mass (strength athletes) or high protein intake, the value can naturally be higher. Conversely, low creatinine in the elderly or in people with little muscle mass can mask reduced kidney function — eGFR is more reliable in those cases.
eGFR (Estimated Glomerular Filtration Rate)
KidneyThe eGFR (estimated glomerular filtration rate) estimates how much blood your kidneys filter per minute. It is calculated from your creatinine level, age, sex, and ethnicity using the CKD-EPI formula. eGFR is more accurate than creatinine alone and is used to classify kidney function loss into stages. An eGFR above 90 ml/min is normal; below 60 ml/min indicates clinically relevant kidney function reduction.
Chronic kidney damage is largely irreversible, but progression can be slowed or stopped if detected early. eGFR is the cornerstone of that early detection. Diabetes and high blood pressure together account for more than 60% of all cases of chronic kidney damage — periodic eGFR monitoring in these patient groups is therefore essential. At an eGFR below 60 ml/min, medication adjustments are often needed because many drugs are excreted by the kidneys. The dosage of contrast agents for CT scans must also be adjusted.
Total Protein
OtherTotal protein measures the combined amount of albumin and globulins in your blood. These proteins play essential roles in maintaining fluid balance, fighting infections, transporting substances, and supporting tissue repair.
Total protein levels provide a general overview of your nutritional status, liver function, kidney function, and immune system activity. Abnormal levels may prompt your healthcare provider to investigate specific protein fractions further.
