About the test

Vitamin B7, also known as biotin, is essential for various metabolic processes, including the synthesis of fatty acids, amino acids, and glucose. Deficiency in biotin can lead to symptoms such as hair loss, skin rashes, brittle nails, neurological issues (e.g., depression, lethargy, hallucinations), and conjunctivitis.

Testing can help diagnose a deficiency and allow for timely intervention to correct it.

DOCTOR'S COMMENTS

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

While biotin deficiency is relatively rare, excessive intake from supplements can interfere with certain laboratory tests, leading to incorrect diagnoses.

For example, high biotin levels can affect tests for thyroid function, hormone levels, and cardiac biomarkers.

Monitoring biotin levels ensures that supplementation is necessary and maintained at a safe level.

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 Vitamin B7 (Biotin) Blood Test.

  1. SPECIAL INSTRUCTIONS FOR TAKING THE VITAMIN B7 (BIOTIN) BLOOD TEST.

    If the purpose of the test is to find the levels of your vitamin supplementation, then you should continue taking these as normal.


    If you are combining this test with any other - please inform us of your supplementation so that we can make sure the results are not affected for tests such as thyroid function. You will most likely have to stop taking your supplements, but do consult your GP.


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 Vitamin B7 (Biotin) 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.

Who should be concerned about biotin deficiency?

Biotin deficiency is relatively rare, but certain groups are at higher risk. These include individuals with genetic disorders like biotinidase deficiency, those on long-term parenteral nutrition, people taking certain anticonvulsant medications, pregnant women, and individuals with chronic alcohol use.

These groups may benefit from regular monitoring of biotin levels to prevent deficiency.

What symptoms might indicate a biotin deficiency?

Signs of biotin deficiency can include hair loss, skin rashes (especially around the eyes, nose, and mouth), brittle nails, fatigue, depression, neurological symptoms (such as numbness and tingling in the extremities), and conjunctivitis.

If you experience any of these symptoms, it's advisable to consult a healthcare provider and consider testing for biotin levels.

How does biotin supplementation interfere with lab tests?

Yes, high levels of biotin from supplements can interfere with various lab tests, including those measuring thyroid hormones, troponin (a cardiac marker), and other hormones. This interference can lead to false results, potentially causing misdiagnosis or inappropriate treatment.

If you are taking biotin supplements, inform your healthcare provider before undergoing lab tests.
