About the Female Hair Loss Blood Test

While hair loss is often genetic, many cases have underlying medical causes that can be treated. If your hair thinning seems abnormal, our test may identify issues to address.

We understand hair loss is distressing, but solutions are possible. Common treatable causes include underactive thyroid, iron deficiency, or low vitamin B12.

Our test checks thyroid function, iron levels, B12, and inflammation markers that could incorrectly alter results. We also assess red blood cell health to screen for anaemia.

By testing key biomarkers related to hair growth, we aim to provide clarity and reassurance. Many causes of shedding and thinning can be improved with straightforward lifestyle adjustments or supplements. You don’t have to live with unexplained hair loss. Answers and treatment options could be closer than you think.

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.

Firstly, we check for hormonal causes of hair loss. We test thyroid function because an underactive thyroid can cause hair loss.

Sometimes hair loss in women occurs when the ovaries produce too much testosterone, a condition known as ‘androgen excess’ which commonly occurs in Polycystic Ovarian Syndrome. The Free Androgen Index (FAI) tests for androgen excess. As it measures your level of biologically active testosterone, FAI is a better test than simply measuring testosterone.

We also test for the hormone prolactin. Prolactin is a hormone that is best known for its role in stimulating breast milk production but chronically raised levels of prolactin have been implicated in hair loss in some studies.

A number of nutritional deficiencies can cause hair loss and so we test your levels of iron (through the marker ferritin) and vitamin B12. These deficiencies are common and easily treated.

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.

Red flag symptoms for the Female Hair Loss Blood Test

Even if your blood tests are normal, you should see a doctor if you have any of the symptoms below because they may be a sign of serious underlying illness:

  • Rapid and widespread hair loss, particularly if this affects parts of your body other than your scalp
  • Scarring at the site of the hair loss
  • You feel generally unwell and are losing hair

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 Female Hair Loss Blood Test.
  • Take this test early in the morning
  • Ideally, stop combined hormonal contraception for a time and use barrier methods instead
  • Take the test between days 2 and 5 of your cycle (where day 1 is the first day of your period). If you don't have periods, take the test at any time
  • 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 Female 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.

Can this test diagnose me with Polycystic Ovarian Syndrome (PCOS)?

A raised Free Androgen Index (FAI) may be suggestive of PCOS but this test can’t properly diagnose PCOS.

The diagnosis is usually made by looking at your symptoms, performing a scan of your ovaries, as well as checking the blood tests.

Can a blood test rule out female pattern hair loss?

No, a standard blood test cannot definitively rule out female pattern hair loss on its own. Female pattern hair loss, also known as female androgenetic alopecia, is the most common type of hair loss in women and is often genetic in nature.

While blood tests can help uncover conditions that may exacerbate hair loss, like thyroid disorders, anaemia, or nutrient deficiencies, they have limitations in diagnosing female pattern hair loss specifically. A combination of clinical assessment, blood work and scalp examination is optimal.

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

Hair loss can be extremely distressing and many people are interested to know how they can slow or prevent it.

Whilst hair loss often runs in families, if you are worried that nutritional deficiencies or hormone imbalances may be causing your hair loss, this test will allow you to check.
