Markers: Homocysteine

Fasting test?

It is better to be fasting for this test. The results may take a little longer, on average between 1-5 working days.

Homocysteine blood test - What is it?

The test measures the amount of homocysteine in the blood. Homocysteine is normally present in all cells, but only in small amounts. In healthy cells, homocysteine is quickly converted into other products. Active folic acid is needed for this conversion. Vitamin B12 and other B vitamins are needed to keep folic acid in its active form.

To To keep homocysteine low, folic acid, vitamin B12 and other B vitamins are necessary. These substances are absorbed through the diet (folic acid: mainly in green leafy vegetables and grain products; Vitamin B6: in vegetables and fruit; Vitamin B12 in meat, fish and poultry). .

In the absence of folic acid and / or vitamin B, the amount of homocysteine increases. Homocysteine can also be (highly) increased due to a hereditary defect, which affects an enzyme involved in the breakdown of homocysteine does not work properly.

When to choose this test?

- The test is requested if a deficiency of folic acid or vitamin B12 is suspected. This is sometimes the case with anemia.

- Also often a homocysteine test for women who have had a repeated spontaneous abortion.

- Sometimes a request for the homocysteine test is made for patients who have suffered a heart or cerebral infarction (blocking of a blood vessel due to a clot) to investigate whether there is an increased risk of a second infarction.
The accuracy of the test for Homocysteine 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 Homocysteine 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 Homocysteine 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.

For example, tests for IVF treatment are often reimbursed. After your order, you will receive an invoice that you can submit to your insurance.

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.
