Hemoglobin Electrophoresis
Hemoglobin electrophoresis is a laboratory technique that separates and identifies different types of hemoglobin in your blood. It is primarily used to detect hemoglobin variants and diagnose inherited blood disorders such as sickle cell disease and thalassemia.
Hepatitis B Core Antibody
The anti-HBc test detects hepatitis B core antibodies, which can indicate past or present exposure to the hepatitis B virus. On its own it does not confirm a current infection. A doctor interprets it alongside other markers such as HBsAg and anti-HBs.
Hepatitis B Surface Antigen
The hepatitis B test detects HBsAg, a marker that can indicate an active hepatitis B infection, whether acute or chronic. It is a data point that needs professional interpretation, not a diagnosis. A doctor can advise on further evaluation.
Hepatitis C Antibody
The Hepatitis C Antibody test is part of comprehensive preventive health screening. This test detects antibodies that indicate exposure to the hepatitis C virus, supporting early detection and proactive health management. A positive result does not confirm active infection and should be followed by confirmatory testing with your healthcare professional.
Herb Pollen Panel (wx3)
The Herb Pollen Panel (wx3) identifies sensitisation to weed pollens. Combining this with grass and tree pollen panels provides a complete picture of your seasonal allergy profile.
Herpes Simplex 1 IgG
This herpes test (HSV-1) is a blood antibody (IgG) test that can show whether you have had earlier contact with herpes simplex virus type 1, which is commonly oral but can also be genital. An IgG result reflects past exposure, not necessarily a current or recent infection. It cannot tell you where or when contact occurred.
Herpes Simplex 2 IgG
This herpes test (HSV-2) is a blood antibody (IgG) test that can show whether you have had earlier contact with herpes simplex virus type 2, which is commonly genital. An IgG result reflects past exposure, not necessarily a current or recent infection. It cannot tell you where or when contact occurred.
Histamine
Histamine blood testing provides insight into mast cell activity and immune reactivity. Combined with DAO and tryptase testing, it forms a comprehensive assessment of histamine-related conditions.
Holotranscobalamin
Holotranscobalamin measures the biologically active B12 available to your cells and is considered the earliest marker of B12 depletion. Monitoring this marker may help detect changes in your B12 status before standard tests.
Homocysteine
Homocysteine is an important cardiovascular risk marker often overlooked. Proactive monitoring supports early intervention and comprehensive heart health screening.
IGF-1 (Insulin-like Growth Factor)
IGF-1 is an important growth factor that reflects your body's repair and regeneration capacity. As part of a comprehensive health assessment, monitoring IGF-1 can help identify potential areas for proactive wellness support.
IGF-BP3
IGF-BP3 is an important binding protein that regulates growth factor activity in the body. As part of comprehensive health screening, testing IGF-BP3 alongside IGF-1 helps provide a fuller understanding of your growth hormone axis.
INR
INR standardises clotting assessment and is essential for warfarin monitoring. Including it in a health panel provides baseline coagulation and liver function information.
Immunoglobulin IgA
Immunoglobulin IgA provides essential immune function data and validates IgA-based screening tests like anti-TTG for coeliac disease.
Immunoglobulin IgG
Immunoglobulin G (IgG) is the most abundant antibody in your blood, forming a critical part of your immune defence. Measuring IgG provides a comprehensive view of your long-term immunity and overall immune resilience.
Immunoglobulin IgM
Immunoglobulin M (IgM) is the first antibody your body produces in response to a new infection, acting as an early warning system. Measuring IgM gives a comprehensive picture of how actively your immune system is responding to potential threats.
Inhalation Allergy Panel
The Inhalation Allergy Panel offers comprehensive screening for common airborne allergens. Identifying your specific triggers enables proactive allergy management and informs decisions about immunotherapy.
Inhibin B
Inhibin B is a gonadal hormone that provides insight into reproductive function in both men and women. As part of comprehensive health screening, this marker can help assess overall hormonal balance.
Insulin (Fasting)
Fasting insulin is one of the earliest indicators of metabolic change. Testing it alongside glucose provides a powerful early warning system for diabetes prevention.
Interleukin-6 (IL-6)
IL-6 provides insight into immune system activity and chronic inflammation. Proactive monitoring supports early detection of inflammatory conditions.
Intrinsic Factor Antibodies
Intrinsic Factor Antibodies tests for an autoimmune cause of B12 deficiency known as pernicious anaemia. This test may help explain why B12 levels remain low despite supplementation and guide your healthcare provider towards appropriate treatment.
Iodine
Iodine supports thyroid function and metabolic health. Routine testing helps catch deficiencies early, especially if your diet limits iodine-rich foods.
Iron (Serum)
Serum iron testing provides insight into your current iron availability. Combined with ferritin and TIBC, it supports comprehensive iron status assessment and early intervention.
Irregular Antibody Screening
An irregular antibody screening test detects unexpected antibodies in your blood that may react against foreign red blood cells. These antibodies can develop after transfusions, pregnancies, or immune stimulation and are important to identify for transfusion and pregnancy safety.
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.
