Sometimes you just want a broad look at how your body is doing, without anything necessarily being wrong. An extended blood test gives you that wider overview: it shows several systems at once, from your blood count to your thyroid, vitamins, lipids, liver and kidneys.
This extended health checkup is our most comprehensive panel, made for women who want to know where they stand with a bit more insight. Instead of a single number, you get a coherent view of fourteen markers that together can say a lot about your everyday health.
Why this test?
Your body works as a whole, and complaints or questions rarely stand on their own. An extended blood test therefore looks at several systems at the same time, so you can spot connections you might miss with a single test.
Some people also call this a complete blood test or a large blood panel. Whatever you call it, the idea is the same. In one draw you measure a broad set of markers and gain a starting point for questions about your health.
Who is this test for?
This extended health checkup can be useful when you want a wider view of your health, for example around a new life stage, with ongoing tiredness or simply out of curiosity.
As a health checkup for women, it fits many situations: you want to know how your vitamins are doing, you are curious about your thyroid, or you want to map your blood fats and sugar values. You do not need a referral from your GP for this.
What is tested?
This panel measures fourteen markers across different systems in your body:
- Complete Blood Count (CBC): a broad view of your red and white blood cells and your platelets.
- TSH (Thyroid Stimulating Hormone): can say something about your thyroid function.
- Free T4: a thyroid hormone assessed together with TSH.
- Free T3: the active form of your thyroid hormone.
- Vitamin D (25-OH): involved in your bones, muscles and immune system.
- Vitamin B12: important for your energy and nervous system.
- Ferritin: gives an impression of your iron stores.
- HDL Cholesterol: the favourable cholesterol.
- LDL Cholesterol: often called the less favourable cholesterol.
- Triglycerides: a type of fat in your blood.
- HbA1c: reflects your average blood sugar over the past two to three months.
- Liver Function Test (LFT): a set of values that can say something about your liver.
- Creatinine: a waste product that says something about your kidneys.
- eGFR: an estimated measure of how well your kidneys filter.
What can this test tell you?
Because this test looks at several systems at once, the results can help you recognise patterns. An unusual value in your blood count, thyroid or vitamins may, for instance, relate to complaints you have been carrying for a while.
Think of signals that could fit with tiredness, a disrupted metabolism or a shortage of certain nutrients. The test can make such clues visible, but on its own it does not make a diagnosis. Above all, it offers insight and starting points to discuss further.
How is the sample collected?
This panel needs one blood draw at a certified lab. In the Netherlands you can choose from 700+ sample locations, so there is a good chance there is one near you.
After ordering, you pick a location and a moment that suits you. The draw usually takes only a few minutes and you do not need a referral for it.
When is this test useful?
An extended blood test can be valuable at different moments, for example:
- when you want a broad overview of your general health
- with vague complaints such as fatigue, when you are not sure where to look
- around a new life stage or a change in your lifestyle
- when you want to track how certain values develop over time
When a test suits you is entirely up to you. Your GP can help you with that if you wish.
What do the results mean?
Your result shows your own value per marker, together with a reference range and a short explanation. In one overview you can see which values fall within the usual range and which differ a little.
A value outside the range does not automatically mean something is wrong; it can also fit with your situation, your lifestyle or the moment of the draw. The BIG-registered doctor helps you place your values in the right context.
What happens after the results?
Your results are usually ready online within a few working days. Each value is shown clearly with a reference range and an explanation, so you can read back what you see at your own pace.
Every blood test result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
Frequently Asked Questions
This panel measures fourteen markers across your blood count, thyroid, vitamins (D and B12), iron, blood fats, long-term blood sugar and your liver and kidney values, giving you a broad overview in one draw.
No, you do not need a referral from your GP. You order the test online and simply pick a sample location near you.
For this panel you usually do not need to fast, because it does not include a fasting glucose. Drinking enough water on the day itself often helps with the draw.
Your results are usually ready online within a few working days, with a reference range and explanation per value, plus an assessment from a BIG-registered doctor.
People often use terms like complete or large blood test for a broad panel like this one. No single test covers every aspect of your health, but this panel does look at many systems at once.

What We Test
This test includes 14 biomarkers to give you a comprehensive health picture.
| No. | Biomarker | Unit | Turnaround |
|---|---|---|---|
| 01 | HbA1c (Glycated Hemoglobin) HbA1c (glycated haemoglobin) reflects your average blood sugar levels over the past 2-3 months. It is the gold standard for long-term blood sugar monitoring and diabetes management. | mmol/mol | 2 days |
| 02 | TSH (Thyroid Stimulating Hormone) TSH is thyroid-stimulating hormone. The pituitary gland makes it, and uses it to drive your thyroid. At the laboratory that runs the test the usual adult range runs from 0.27 to 4.20 mE/L. A high TSH usually fits an underactive thyroid. A low value usually fits an overactive one. That direction feels inverted, and it is. TSH is the pituitary signal, not the thyroid hormone itself. Laboratories use slightly different limits from one another. Always read the reference value printed on your own result. And a single measurement is never a diagnosis. | mu/l | 2 days |
| 03 | Triglycerides Triglycerides are the most common type of fat in the body, used for energy storage. Elevated levels may be associated with increased risk of cardiovascular disease, especially when combined with other lipid abnormalities. | mmol/l | 1 day |
| 04 | Creatinine Creatinine is a waste product that is continuously produced in your muscles. The kidneys filter it out of the blood and remove it in urine. The blood creatinine level is therefore a core number for kidney function. In Dutch it is written both as creatinine and as kreatinine. Because production depends on your muscle mass, the same figure reads differently per person. A raised creatinine does not automatically point to a kidney problem. This page explains what high and low values can mean. It also covers the everyday things that shift the result temporarily. | umol/l | 1 day |
| 05 | eGFR (Estimated Glomerular Filtration Rate) eGFR (estimated glomerular filtration rate) is a calculated measure of how effectively your kidneys filter waste from the blood. It is the gold standard for diagnosing and staging chronic kidney disease and is derived from blood creatinine or cystatin C levels along with demographic factors. | ml/min/1,73m² | 1 day |
| 06 | Free T4 (Thyroxine) Free T4 (thyroxine) is the main hormone produced by the thyroid gland. It may serve as a precursor that your body converts into the more active T3. Healthcare providers often consider Free T4 a primary indicator of thyroid gland output. | pmol/l | 4 days |
| 07 | LDL Cholesterol LDL cholesterol is the amount of cholesterol carried inside LDL particles, the particles that can build up in the artery wall. That is where its nickname comes from: the bad cholesterol. Two things rarely appear on a report. First, in a routine lipid panel LDL is usually not measured but calculated from your total cholesterol, your HDL and your triglycerides. Second, the 3.0 mmol/l upper limit is a population reference interval, not a target. What counts as a good LDL for you is decided by your overall cardiovascular risk, not by the line printed on the page. | mmol/l | 1 day |
| 08 | Liver Function Test (LFT) A liver function test is a comprehensive blood panel that combines multiple markers to assess overall liver health and function. It typically includes enzymes such as ALT, AST, and GGT, along with bilirubin, albumin, and other indicators to provide a complete picture of how well the liver is performing. | — | 4 days |
| 09 | Vitamin B12 Vitamin B12 is considered essential for red blood cell formation, neurological function, and DNA synthesis. Deficiency may develop gradually and is sometimes associated with dietary patterns. Healthcare providers can help interpret your results. | pmol/l | 3 days |
| 10 | Vitamin D (25-OH) Vitamin D is a fat-soluble vitamin. Its main job is the absorption of calcium and phosphate from the gut. That makes it decisive for bone metabolism. The skin produces it under the influence of sunlight. Food and supplements supply a smaller share. | nmol/l | 3 days |
| 11 | Free T3 (Triiodothyronine) Free T3 (triiodothronine) is considered the most active thyroid hormone. It may play a key role in regulating metabolism, energy production, and body temperature. Healthcare providers often assess Free T3 alongside other thyroid markers for a comprehensive picture. | pmol/l | 4 days |
| 12 | Ferritin Ferritin is a protein that stores iron, so your ferritin level shows how large your iron reserve is. Serum iron only measures how much iron is circulating in your blood at that moment; ferritin describes the reserve behind it. That reserve empties before your haemoglobin falls, so a low ferritin can already cause symptoms while your blood count still looks normal. Ferritin also rises with inflammation, infection and liver strain, which is why it can only be read properly alongside a CRP. Commonly used reference values are 30 to 400 µg/l for men and 15 to 150 µg/l for women, but your own laboratory report is what counts. | ug/l | 2 days |
| 13 | HDL Cholesterol HDL cholesterol is the amount of cholesterol carried inside the HDL particles in your blood. Those particles pick cholesterol up from your tissues and from the artery wall and take it back to the liver. That transport is what earned HDL the nickname good cholesterol. The nickname is misleading. HDL is above all a mirror of your metabolism: the value drops with excess weight, insulin resistance, smoking and inactivity, and it is those factors that carry the risk. Drugs that raise HDL substantially do not reduce the number of cardiovascular events. And more is not always better: at very high values, mortality in large population studies turns back upwards. So never read your HDL on its own. It only takes on meaning alongside your triglycerides, your LDL and your overall risk profile. | mmol/l | 1 day |
| 14 | 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. | — | 2 days |
| Your result arrives once the slowest test is finished: 4 days. This is indicative; turnaround varies per laboratory. | |||
Preparation
-
Been ill? Wait a little
RequiredHad a fever, an infection or a vaccination in the past 2 weeks? Wait with the draw until you are fully recovered. These values react to inflammation and would give a distorted picture.
-
Pause biotin
RequiredDo you take a supplement with biotin (vitamin B8, common in hair, skin and nail supplements)? Stop it 72 hours before the draw. Biotin interferes with the measurement of these values.
-
Better no hard training beforehand
RecommendedHard exercise in the 48 hours before can raise this value temporarily. Plan the draw on a rest day if you can.
-
No alcohol beforehand
RequiredDrink no alcohol in the 24 hours before the draw.
-
Preferably fasting
RecommendedComing fasting gives a slightly cleaner value, but it is not required. If it suits you, eat nothing from 22:00 the evening before and drink only water.
-
Timing worth knowing
Good to knowIf you repeat this test, pick the same time of day each time so the results compare.
-
On levothyroxine? Worth knowing
Good to knowTell the staff at the draw when you took your tablet; for most values the timing makes no difference.
- Water is always fine. Drink as usual beforehand, it makes the draw easier.
- Take your usual medication, unless your own doctor told you otherwise.
