Antithrombin III (Activity)
Antithrombin III Activity testing assesses your most important natural anticoagulant. Including this in a thrombophilia screen provides critical information about inherited or acquired clotting risk.
Antithrombin III (Concentration)
Antithrombin III Concentration complements the activity test for comprehensive thrombophilia screening, classifying any deficiency to guide preventive care.
ApoA1 (Apolipoprotein A1)
ApoA1 provides deeper cardiovascular insight than standard HDL testing. Including it in your lipid panel supports comprehensive heart disease risk assessment.
ApoB (Apolipoprotein B)
ApoB is considered one of the best predictors of cardiovascular risk. Including it in your health screening provides actionable insight for heart disease prevention.
Arsenic
As part of comprehensive health screening, an arsenic blood test helps you understand your environmental exposure to this potentially harmful element. Knowing your arsenic levels is an important step in taking charge of your health.
Autoimmune Hepatitis Panel
The Autoimmune Hepatitis Panel provides comprehensive screening when immune-mediated liver disease is suspected. Early diagnosis is key to preventing cirrhosis.
Basic Blood Count
A basic blood count measures three core values in your blood: hemoglobin, white blood cells and platelets. Together they say something about oxygen transport, immune defence and clotting. It is a simple baseline check, without the red-cell indices and white-cell differential of a complete blood count.
Basophils
Does your result say basophil granulocytes? Those are white blood cells, and there are fewest of these. In adults the basophil granulocyte value sits between 0 and 0.2 x10⁹/l. That is 0 to 2 percent of your white blood cells. A low value or a zero is normal and means nothing. A rise above 0.2 is uncommon and usually calls for a repeat first. That is because the machine counts this particular cell poorly. Below you can read in plain language what your number means. And when to take it to your GP.
Beta-2 Glycoprotein Screening
Beta-2 glycoprotein screening completes the antiphospholipid antibody panel, ensuring no APS case is missed through incomplete testing.
Bicarbonate
Bicarbonate is essential for maintaining acid-base balance. Monitoring this electrolyte helps detect metabolic imbalances early and supports overall health management.
Bilirubin (Direct)
Direct bilirubin testing provides insight into your liver's ability to process and excrete waste products. Regular monitoring supports early detection of bile duct or liver conditions as part of proactive health management.
Bilirubin (Total)
Total bilirubin is a fundamental marker of liver function and red blood cell health. Regular monitoring helps detect potential liver or blood conditions early, supporting informed and proactive health decisions.
Blood Type + Rh
A blood type test determines your ABO blood group and Rh factor. Knowing your blood type is essential for safe blood transfusions, organ transplants, and pregnancy planning.
Borrelia IgG (Lyme Disease)
A Borrelia IgG test detects IgG antibodies against Borrelia burgdorferi, the bacterium that causes Lyme disease. A positive result may indicate a past or late-stage infection, as IgG antibodies typically develop several weeks after initial exposure.
Borrelia IgM (Lyme Disease)
A Borrelia IgM test detects IgM antibodies against Borrelia burgdorferi, the bacterium responsible for Lyme disease. A positive result may indicate a recent or early-stage infection, as IgM antibodies are typically the first to appear after exposure.
C-Peptide
C-Peptide provides early insight into pancreatic function and insulin resistance. Proactive testing supports early detection of metabolic changes before diabetes develops.
C3 Complement
C3 Complement provides essential information about complement system function. It is valuable for monitoring autoimmune conditions and evaluating immune complex disorders.
CA 15-3
CA 15-3 is a protein associated with breast tissue that can be measured as part of a preventive health assessment. Including CA 15-3 in a routine panel helps establish a personal baseline for ongoing monitoring.
CA 19-9
CA 19-9 is a gastrointestinal marker that can be measured as part of a preventive health assessment to establish a personal baseline. Many benign conditions raise this marker, so results should always be reviewed by a healthcare professional.
CA 72-4
CA 72-4 is a gastric marker that can be measured as part of a preventive health assessment to help establish a personal baseline.
CA-125
A CA-125 test is part of a comprehensive health picture, measuring a protein that can be associated with various conditions. Elevated values have many possible explanations, including common benign gynecological conditions such as endometriosis and menstruation, as well as liver disease. This test alone cannot diagnose cancer and your healthcare professional will interpret the results alongside other clinical information to provide a complete and reassuring assessment.
CEA (Carcinoembryonic Antigen)
CEA is a broad tumor marker measurable as part of a preventive health assessment. Establishing a personal baseline and tracking trends over time is more informative than any single result.
CK-MB
CK-MB is a valuable cardiac marker for detecting heart muscle damage early. Including it in your health screening supports comprehensive cardiac risk assessment.
CMV IgG
A CMV IgG test detects IgG antibodies against cytomegalovirus (CMV) in your blood. A positive result typically indicates a past CMV infection and suggests that your immune system has developed long-term immunity to the virus.
What are blood values?
Blood values are the substances a laboratory measures in your blood. Think of haemoglobin, cholesterol, glucose and thyroid hormones. Each value comes back as a number with a unit. A reference range is printed beside it.
That reference range is the band most healthy people fall within. A result outside it is called an abnormal value. Abnormal does not mean ill. It is mainly a signal that needs context.
Why have your blood values measured?
A doctor orders blood work for several reasons. To make a diagnosis, or to rule something out. To look for the cause of a complaint. Or to follow how a treatment is working.
You can also have your blood values measured yourself, without a referral from a GP. People do this when they are tired for no clear reason. Or when they want to know how their liver, kidneys and metabolism are doing. A baseline is also useful if you want to compare later.
Which blood values are measured most often?
Most testing comes down to a handful of groups. The blood count measures your red cells, white cells and platelets. Liver values and kidney values show how those organs are working.
The thyroid, the vitamins and iron are also measured often. Cholesterol and glucose belong to the heart and metabolic profile. Inflammatory values show whether there is inflammation somewhere in your body. You can filter by category above.
What counts as a normal blood value?
There is no single list of normal values that applies everywhere. Reference ranges may vary between laboratories. This comes down to differences in method, equipment and the groups studied. So always read the reference range printed on your own result.
Age and sex matter too. Haemoglobin runs higher in men than in women on average. Children have different numbers again. Every value page above carries the range that belongs to it.
How do you read your result?
A single value says little on its own. Doctors look at the pattern across several values. A raised ALT alongside a raised gamma-GT points somewhere different than a raised ALT alone.
When you test through us, a BIG-registered doctor assesses your results in context. So you get back more than numbers. Always discuss treatment decisions with your GP.
Where do you get your blood drawn?
We work with independent, certified laboratories across the Netherlands. The collection points are run by those laboratories. You do not need a referral from a GP.
You choose which blood values you have measured. After the draw you get your result back digitally, with an explanation per value.
Frequently asked questions about blood values
- Which blood values are normal?
- That differs per value, per laboratory and per person. Reference ranges depend on the method used, your age and your sex. Look the value up above and read the range that belongs to it. Always compare it against the reference range on your own result.
- Which blood value indicates cancer?
- General blood work is not a suitable way to detect cancer. An abnormal value can have many different causes. Separate screening programmes exist for bowel, breast and cervical cancer. If your complaints persist, see your GP.
- What are perfect blood values?
- Perfect blood values do not exist. A reference range is a band, not a target number. Someone can sit at the edge of that band and be entirely healthy. What your values mean depends on your complaints and your history.
- Which blood value indicates inflammation?
- CRP is the most widely used inflammatory value in the Netherlands. The sedimentation rate, also called ESR, is used alongside it and responds more slowly. Both show that inflammation is present somewhere. Neither says where in your body it sits.
Reference ranges may vary between laboratories. When you order a test, a BIG-registered doctor assesses your personal results in context. For treatment decisions, discuss your results with your GP.
