Look up a blood value
A blood value shows how your body is doing on the inside. You will find them all here in one place, with no referral from a GP. Pick a value and read its reference range. You also see what an abnormal result can mean.

17-OH Progesterone
17-OH Progesterone is a steroid hormone your body uses to produce cortisol and sex hormones.
ACTH (Adrenocorticotropic Hormone)
ACTH is a pituitary hormone that controls cortisol production by your adrenal glands.
AFP (Alpha-Fetoprotein)
An AFP (Alpha-Fetoprotein) test is part of a comprehensive health picture, measuring a protein that can be associated with various liver conditions.
ALP (Alkaline Phosphatase)
Your alkaline phosphatase tells you how busy your bones and your bile ducts are, and one number just outside the line says little on its own.
ALT (Alanine Aminotransferase)
Your ALT value tells you whether your liver cells are being damaged.
AMA (Anti-Mitochondrial Antibodies)
AMA is the key serological marker for primary biliary cholangitis. Including it in an autoimmune screen enables early detection and timely treatment initiation.
AMH (Anti-Müllerian Hormone)
Your AMH value tells you how many small follicles are still sitting in your ovaries, and doctors call that number your ovarian reserve.
ANA (Antinuclear Antibodies)
ANA is the first-line autoimmune screening test. Including it in a comprehensive panel helps identify autoimmune conditions early, when treatment is most effective.
ANCA Screening
ANCA screening is important when autoimmune vasculitis is suspected. Early identification of ANCA positivity enables timely specialist referral and treatment.
AST (Aspartate Aminotransferase)
Your AST value tells you whether cells somewhere in your body have been damaged, and far from always are those liver cells.
ASTO (Antistreptolysin O)
ASO testing helps detect post-streptococcal complications early. Including it in your health screening supports timely intervention and preventive care.
Active Vitamin B12
Active Vitamin B12 measures the bioavailable form of B12 your body can readily absorb and use.
Albumin
Albumin is a broad indicator of liver, kidney, and nutritional health. Including it in your health screening provides foundational insight into overall well-being.
Albumin-to-Creatinine Ratio (ACR)
Albumin loss through the kidneys begins without symptoms, and this ratio shows it before your eGFR moves.
Aluminum
As part of comprehensive health screening, an aluminum blood test helps you understand your environmental exposure to this common metal.
Amitriptyline
Amitriptyline monitoring is part of a comprehensive approach to managing your prescribed medication. Tracking blood levels helps your healthcare team ensure your treatment plan is both safe and effective.
Amylase
Amylase testing provides insight into pancreatic and digestive health. Regular monitoring supports early detection of pancreatic conditions.
Androstenedione
Androstenedione is a precursor hormone that your body converts into sex hormones like testosterone and estrogen.
Anti ds-DNA + ss-DNA
Anti ds-DNA is one of the most specific tests for lupus. Including it in an autoimmune panel provides definitive information for SLE evaluation.
Anti-CCP
Anti-CCP is the gold standard serological test for rheumatoid arthritis. Early detection through proactive screening enables treatment before irreversible joint damage occurs.
Anti-Cardiolipin IgG
Anti-cardiolipin IgG is a key marker for antiphospholipid syndrome. Including it in an autoimmune screen helps identify this treatable cause of thrombosis.
Anti-Cardiolipin IgM
Anti-cardiolipin IgM completes the antiphospholipid antibody panel for comprehensive APS risk assessment.
Anti-HAV (Hepatitis A Antibody)
An Anti-HAV test is part of a comprehensive health screening that checks your immunity against hepatitis A.
Anti-HBs (Hepatitis B Immunity)
An Anti-HBs test is part of a comprehensive health screening that confirms your immunity to hepatitis B.
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.
