iFOBT Colon cancer screening

Markers: iFOBT

The FOBT test shows whether there are traces of blood in the stool (faeces, feces) that are not visible to the eye. Hence the term occult test. Blood in the stool can have various reasons. For example, there may be an ulcer, bulges, polyps, inflammation, hemorrhoids or, more rarely, a tumor. Fortunately, these tumors in the colon are relatively rare. However, an early test can ensure early recognition and therefore a better outcome for survival .

The stool for the FOBT test is collected in a jar. This includes a scoop so that the hands remain clean. A few days in advance it is advisable to take raw not to eat vegetables and meat. We also advise against painkillers.

What do we determine during the FOBT Test Large Intestine Fecal Examination?

Large Intestine: Occult blood in the stool

An FOBT test is to detect colon cancer as early as possible. The sooner a possible tumor is discovered, the better the chances for cure and treatment. The FOBT test is not sufficient to definitively diagnose colon cancer. There are many causes of blood in the stool. Therefore, additional research must be conducted. After all, blood in the stool can be accidental. Is the result still positive after a second test? You will then be referred to the hospital to confirm the diagnosis with an examination of the intestines. We can help you with a referral through your GP.

The FOBT test is also used to detect causes of anemia. Anemia can have various reasons, but bleeding in the stomach or intestines is not easily noticed. However, bleeding in the stomach can cause continuous blood loss and therefore fatigue and weakness.

The result of the FOBT test is usually negative. This means that no blood has been detected in the sample sent. If blood is detected during the FOBT test, this means that blood has been found in the sample. Then additional research must take place. We will first take several samples to see whether there is consistent blood in the stool. If these other FOBT tests are also positive, we will recommend an examination of the (large) intestines.


The results of the FOBT test take approximately 7 working days after arrival of the material in the laboratory.

The accuracy of the test for iFOBT Dikke Darm is conducted through ISO-certified laboratories. The accuracy of a test method is expressed in terms of specificity and sensitivity. However, the most important aspect is that the results are interpreted and accepted among general practitioners and hospitals. This is the case with our venous samples. Mutual acceptance may not always be present due to potentially reduced reliability with a capillary sample.
Most tests generally take 24-48 hours. Tests that go through an LC-MS method generally take longer, think about an average of 3-7 working days. Additionally, it also depends on the location. Some locations do the analysis themselves and others outsource it to another lab.
Interpreting the results of iFOBT Dikke Darm is not always easy and should be seen in the broader picture, along with anamnesis and physical examination. In the doctor's advice section, the query in which you can already outline your complaints is taken into account, otherwise, the results are interpreted in conjunction with the other results. If necessary, the doctor can call to ask about physical abnormalities. You don't have to interpret the results yourself because there is always advice and explanation from the doctor.
If the results of the test for iFOBT Dikke Darm are clinically significantly abnormal, the doctor will contact you by phone. If you are not reachable, you will receive an email. This includes advice and an explanation of the abnormal results and what you can do about them. If you need a prescription or referral, we can help with that.
The costs of iFOBT Dikke Darm can be found on the product page. Depending on your insurance and additional packages, you may be reimbursed for these costs for iFOBT Dikke Darm.

For blood tests, we always use venous sampling. This is the gold standard for blood collection. Over-the-counter tests, such as a finger prick test, use the capillary route for blood collection. These do not always give the same results and the accuracy depends on how, where, and with which technique the collection is done. The advantage, of course, is that the test is easier and less painful to take.
You can always pay with iDeal and credit card (VISA, Mastercard, and Amex). This also includes Apple Pay. The phlebotomists at the collection location cannot accept cash payments.
The results of Labplusarts can be shared with your general practitioner at your request. However, you can also easily arrange this yourself by downloading the result in PDF format. Because we use comparable test methods as the general practitioner, the results are interchangeable and comparable so that comparisons can be made well.
