What is a hair loss blood test?

With hair loss (alopecia) you lose an above-average amount of hair. There are different types of hair loss. You may losing a lot of hair at once, or whether it is a gradual process. Hair loss can be caused by various factors. Blood tests can be used to look at the underlying causes of hair loss. This can help find a treatment.

What do we determine in the hair loss blood test?

Cortisol (stress hormone)
The other name for cortisol is also the stress hormone. It has been shown that stress can cause hair loss. Cortisol can influence the growth of hair follicles. This determination looks at the amount of cortisol in your body. These values vary during the day, the cortisol level is highest in the morning and lowest in the evening.

Thyroid gland: TSH & fT4
Your thyroid gland can also have an effect on hair loss. An over- or under-active thyroid gland can cause hair loss. The TSH determination shows how much thyroid stimulating hormone is present in the blood. TSH controls the production of the thyroid hormones free T4 and T3. When the TSH value is higher or lower, the thyroid gland does not function normally and the thyroid gland is either underactive or overactive. With a normal TSH value it is often assumed that the other values are also good. Therefore, fT4 is normally only tested when the TSH is abnormal. At Labplusarts, both values are included in the research, because this provides a clearer insight.

Vitamin B12
A consequence of a vitamin B12 deficiency may be that you suffer from hair loss. By means of this provision we can check whether this is the case.

An iron deficiency can also cause hair loss. An iron deficiency occurs regularly and can be caused by, for example, blood loss or pregnancy. A blood test for iron can show whether this is the case. An iron deficiency can often be remedied through the right diet and / or supplements.

The protein ferritin is what ensures the connection between iron and the red blood cells. If this is too low, it may indicate an iron deficiency.

In most cases the results are known within 24 hours. Please have cortisol determinations done at 8:00 am.

Why blood tests for hair loss?

Hair loss is annoying, and the reason is not always clear. This blood test can help you you can determine the possible underlying reason. This way you can see whether treatment is possible.
The accuracy of the test for Haaruitval 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 Haaruitval 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 Haaruitval 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 Haaruitval can be found on the product page. Depending on your insurance and additional packages, you may be reimbursed for these costs for Haaruitval. For example, tests for IVF treatment are often reimbursed. After your order, you will receive an invoice that you can submit to your insurance.
The ordering process is easy. You can add a Haaruitval test or the tests you want to your shopping cart. In step two, you fill in your details and pay. Then you will receive an email confirmation and you can go to a collection location. After you have been there, you will receive the results of the Haaruitval test in your Portal.
We are certified-ready according to the NEN 7510 and 7512 standards for secure data transfer in healthcare. The Portal is secured with two-factor authentication. Your data is also encrypted. We do not send the results of Haaruitval to third parties without permission, not even to your general practitioner without your consent.
The blood test for Haaruitval must take place at one of the collection locations we provide. At certain locations, it is possible for a phlebotomist to come to you. You can indicate this during checkout. An appointment will then be made as soon as possible to come to your home.
You can easily make an appointment for Haaruitval blood test after your order in your Portal. You can visit almost daily in all major cities in the Netherlands. In smaller cities, you can visit on certain days. At certain locations, it is also possible to visit on weekends.
An interpretation by a doctor or an explanation is included in the Haaruitval test. The explanation takes into account the query that you can specify in your Portal after ordering.
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.
