D-Dimer
D-Dimer is a sensitive marker of clotting activity. As part of a health assessment, it provides valuable information about fibrin turnover and thrombotic risk.
DAO (Diamine Oxidase)
DAO testing helps identify histamine intolerance — a common but underdiagnosed cause of recurring headaches, digestive complaints, and skin reactions. Including DAO in a preventive health panel provides actionable dietary insights.
DHEA-S
DHEA-S is the most abundant adrenal hormone and a reliable marker of overall adrenal function. Its age-related decline makes it a valuable indicator for preventive health monitoring.
DHT (Dihydrotestosterone)
DHT is the most biologically active androgen and provides important insight into how testosterone is being metabolised. Including DHT in your panel offers a more complete hormonal picture.
Dengue IgG
A Dengue IgG test detects IgG antibodies against the dengue virus in your blood. A positive result may indicate a past dengue infection, as IgG antibodies typically develop one to two weeks after initial exposure and can persist for years.
Dengue IgM
A Dengue IgM test detects IgM antibodies against the dengue virus in your blood. A positive result may indicate a recent or active dengue infection, as IgM antibodies are typically the first to appear within days of symptom onset.
Dengue Virus NS1
A Dengue NS1 test detects the NS1 (non-structural protein 1) antigen of the dengue virus in your blood. This test is particularly useful for early detection during the first few days of illness, before antibodies have developed.
Digoxin
Digoxin monitoring is a vital component of managing your prescribed heart medication. Due to its narrow therapeutic window, regular blood level checks are essential to ensure your treatment remains both safe and effective.
Dopamine (Urine)
Dopamine is a fundamental neurotransmitter for mood, motivation, and cognitive function. Including this test in your panel provides valuable insight into overall neurological and adrenal health.
EBV EBNA IgG
An EBV EBNA IgG test detects IgG antibodies against the Epstein-Barr nuclear antigen (EBNA). A positive result typically indicates a past EBV infection, as EBNA antibodies develop weeks to months after the initial infection and usually persist for life.
EBV VCA IgG
An EBV VCA IgG test detects IgG antibodies against the Epstein-Barr virus viral capsid antigen (VCA). A positive result may indicate a past or current EBV infection, as VCA IgG antibodies typically appear during the acute phase and persist for life.
EBV VCA IgM
An EBV VCA IgM test detects IgM antibodies against the Epstein-Barr virus viral capsid antigen (VCA). A positive result may indicate an acute or recent EBV infection, as VCA IgM antibodies are typically the first to appear and usually decline within a few months.
ENA (Extractable Nuclear Antigens)
ENA testing provides specific autoimmune disease classification when ANA is positive. Each antibody points to a different condition, enabling targeted evaluation.
ESR (Erythrocyte Sedimentation Rate)
Your ESR tells you how fast red blood cells settle in an upright tube. After exactly one hour, the lab measures how much clear plasma sits at the top. If nothing unusual is happening, those cells drift down slowly. During inflammation certain proteins in the blood rise. They stick the cells together, so the red cells fall faster. On your result this often appears as ESR or BSE. It does not measure the inflammation itself, but its effect on your blood. That is why you usually get a second value alongside it.
Elastase (Pancreatic)
Pancreatic elastase testing provides a non-invasive assessment of your pancreatic digestive function. As part of a comprehensive health evaluation, it can help identify digestive concerns related to pancreatic enzyme production.
Endomysium IgA
A normal endomysial IgA (EMA) result is negative. EMA is reported as negative or positive with a titre rather than as a number; a positive result is highly specific for celiac disease and is virtually always interpreted together with anti-tTG IgA.
Eosinophils
Eosinophils are white blood cells involved in allergic reactions and the defence against parasites. They are part of your complete blood count. A raised count is often seen with allergies, asthma or a parasitic infection, while a low count is usually not a concern.
Erythrocytes (RBC)
An erythrocyte (red blood cell) count measures the number of red blood cells in your blood. Red blood cells are responsible for carrying oxygen from your lungs to the rest of your body and transporting carbon dioxide back for exhalation.
Estradiol (E2)
Estradiol (E2) is the most active form of estrogen, contributing to bone strength, heart health, and emotional wellbeing. Monitoring your levels may help identify hormonal shifts early. Discuss your results with a healthcare provider for personalised guidance.
Estrone (E1)
Estrone (E1) is a weaker form of estrogen that becomes increasingly important with age. Produced mainly in fat tissue, it reflects your body's estrogen activity after reproductive years. Monitoring E1 may help your healthcare provider assess your overall hormonal health.
FSH (Follicle Stimulating Hormone)
Follicle-stimulating hormone (FSH) is produced by the pituitary gland and is essential for reproductive function throughout life. Monitoring FSH may help detect age-related hormonal changes early. Your healthcare provider can help you understand your results in the context of your overall health.
Factor V Leiden
Factor V Leiden is the most common inherited thrombophilia. This one-time genetic test provides lifelong information about your clotting risk.
Ferritin
Ferritin is a protein that stores iron, so your ferritin level tells you how large your iron store is. Think of it as the store cupboard rather than what is on the table right now, which is serum iron. That store empties before you become anaemic, so you can already feel tired while your blood count still looks fine. There is one thing you need to know to make sense of your result: ferritin also rises when you have an inflammation or infection. That is why a CRP always belongs alongside it. Without that second value you cannot tell whether a normal figure is genuinely normal.
Fibrinogen
Fibrinogen provides dual insight into clotting function and inflammatory status. Including it in a health panel delivers valuable cardiovascular risk information.
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.
