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.

284 markers Searching...
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.
CMV IgM
A CMV IgM test detects IgM antibodies against cytomegalovirus (CMV) in your blood.
CRP (C-Reactive Protein)
Your CRP value tells you how large an inflammatory response is running somewhere in your body right now.
Cadmium
As part of comprehensive health screening, a cadmium blood test helps you understand your environmental exposure to this toxic heavy metal.
Calcitonin
Calcitonin is a hormone from the thyroid C-cells that helps manage calcium levels and bone health.
Calcium
Your calcium level shows how much calcium is in your blood, in mmol/l, and for adults a normal result is 2.18 to 2.55 mmol/l.
Carbamazepine
Carbamazepine monitoring is an important part of managing your prescribed anticonvulsant therapy. Regular blood level checks support your healthcare team in maintaining effective and safe treatment.
Carnitine Differentiation
Carnitine differentiation provides insight into your body's fatty acid metabolism as part of a comprehensive health assessment. Understanding your carnitine profile can help identify energy metabolism concerns early.
Ceruloplasmin
Ceruloplasmin testing helps evaluate copper balance and liver function. Including it in your health checks supports early detection of metabolic imbalances.
Chlamydia (PCR)
This PCR test looks for the DNA of Chlamydia trachomatis, the most common bacterial STI. The sample is usually urine or a swab, not blood.
Chlamydia IgG
This blood test looks for IgG antibodies, which can indicate past or earlier exposure to chlamydia rather than a current acute infection.
Chloride
Chloride is a key electrolyte for fluid and acid-base balance. Regular monitoring supports early detection of hydration issues and metabolic disturbances.
Cholesterol/HDL Ratio
The cholesterol/HDL ratio is your total cholesterol divided by your HDL. A lower ratio points to a more favourable profile and a lower cardiovascular risk.
Citrate
Urinary citrate testing provides insight into your kidney stone risk. Maintaining healthy citrate levels is an important part of proactive kidney health management and stone prevention.
Coenzyme Q10
Coenzyme Q10 testing offers insight into your cellular energy production and antioxidant status.
Complete Blood Count (CBC)
Your blood count tells you how many red blood cells, white blood cells and platelets your blood holds and how much haemoglobin you have, and on your result you see that as a row of abbreviations with numbers beside them.
Coombs Test (Indirect)
The indirect Coombs test screens for unexpected antibodies in your blood that may react against red blood cells. It is an important test for transfusion safety and prenatal care.
Copper
Copper is essential for many enzymatic processes. Monitoring helps ensure balanced mineral levels and supports preventive health management.
Cortisol
Cortisol is a key indicator of how your body manages stress. Regular monitoring provides insight into adrenal health and its downstream effects on metabolism and immunity.
Covid-19 IgG
A Covid-19 IgG test detects IgG antibodies against SARS-CoV-2, the virus that causes Covid-19.
Covid-19 PCR
A Covid-19 PCR test detects the genetic material (RNA) of SARS-CoV-2 in a sample.
Creatine Kinase (CK)
Creatine kinase testing provides a clear picture of your muscle health as part of a comprehensive health assessment.
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.
