About the Male Hair Loss Blood Test

While genetics influence hair loss, medical conditions can also trigger or worsen thinning for some. If you notice an abnormal pattern, our blood test may identify contributing issues to address.

Certain nutritional shortfalls are a common and treatable cause. We check iron, B12 and vitamin D levels. An underactive thyroid can also disrupt healthy hair.

By measuring inflammation and complete blood cell health, we rule out distorting factors and gain a big-picture view. Comprehensive insights help pinpoint potential reasons for unhealthy follicles.

In many cases, simple lifestyle adjustments or supplements may help promote growth. You do not have to accept unexplained hair loss as inevitable. Our test offers clarity on underlying causes so you can take proactive steps.

Doctor's notes

Hi, I am Dr. Adam Staten and here's my view on this test as a GP and Clinical Director at One Day Tests.

Although hair loss is common, it is often very distressing. There are a number of conditions that can cause or worsen hair loss, some of which are very straightforward to treat.

A number of nutritional deficiencies can cause hair loss, so we test your levels of iron (through the marker ferritin), vitamin B12 and vitamin D. These deficiencies are common and easily treated. We also test thyroid function because an underactive thyroid can cause hair loss.

We check the inflammatory marker CRP to help exclude autoimmune conditions and to make sure we can accurately interpret your ferritin which can be artificially raised in inflammatory conditions.

Lastly, we check your full blood count which is a good marker of your general health and will also check to see if you are anaemic, which can occur if you are deficient in iron or B12.

Special instructions

Hi, I am Stefania Brown, I am the Laboratory Manager at One Day Tests and here are the lab's special requests for the Male Hair Loss Blood Test.

If you take biotin supplements, stop taking these for 72 hours before the test.

Take this test after any symptoms of short term illness have settled.

Venepuncture appointment - how to prepare

If you are coming into one of our clinics for the test, this is what you need to do before you arrive:

  • Drink plenty of water about an hour before the appointment.
  • Avoid coffee/tea/energy drinks. Water is good!
  • That’s it! We’ll do the rest.

Home test kit for Male Hair Loss Blood Test - how it works

Our blood test kits are simple and convenient.

The most important step in doing a blood test at home is to read the instructions very carefully. The process is very simple, but there are a few pitfalls you need to be aware of - you will save yourself a lot of time if you do it right the first time around!

  • Full printed instructions will arrive with your kit - please read them carefully.
  • Drink plenty before taking the sample and warm your hands up in the sink with warm water for a few minutes. This will make your blood flow much better.
  • Fill the tubes to the top line. We don’t need much blood; filling tubes to the top line is about 15 drops of blood.
  • Post the samples on the same day you take them, before midday, Monday to Thursday. If you post it any other time it might get to us late or be stuck at a sorting office over the weekend. You will then have to do it again.
  • Package the sample in the same box the kit came in. Otherwise, Royal Mail or DPD will reject it. The sample tubes go into a pouch, then into a cardboard box, and then into a return envelope. All of this is provided in the kit: please use it.

We look forward to receiving your sample in our lab!

Frequently Asked Questions

Hi, I am Lana Nela, Lead Nurse, and here is what we are frequently asked about this test.

Why are you not testing my testosterone levels?

Whilst testosterone is implicated in the process of male pattern baldness, men suffering from male pattern baldness have not been found to have abnormal levels of testosterone. The problem appears to be with the effect of testosterone on the hair follicles, not the actual level of testosterone. Measuring your testosterone level is therefore not helpful.

Why take this test?

Hi, I am Dr. Marco Esposito and here is why it's important to take this test.

You are worried about an underlying medical cause of your hair loss.

Is this test right for you?
