Vitamin B7 (Biotin) Test at Home in Dubai
Also known as: BIOTIN, VIT B7, VITAMIN H
Included
About the Test
The Vitamin B7 (Biotin) test measures the level of biotin, a B-vitamin your body needs to convert food into energy and to support healthy hair, skin and nails. True deficiency is uncommon but can occur with prolonged raw-egg consumption, certain genetic conditions, long-term antibiotic or anti-seizure use, or malabsorption, sometimes showing as hair thinning, brittle nails or skin rashes. The test is used both to investigate these symptoms and, importantly, to check biotin levels because high-dose supplements can interfere with other blood tests.
What is it? A blood test measuring biotin, also called vitamin B7, VIT B7 or vitamin H.

Vitamin B7 (Biotin) test: purpose, preparation and results
Why take the Vitamin B7 (Biotin) test?
- To investigate hair thinning, brittle nails or unexplained skin and scalp changes.
- To assess status in people with malabsorption, on long-term antibiotics or anti-seizure medicines, or with relevant genetic conditions.
- To document biotin intake, since high-dose supplements can distort thyroid, hormone and cardiac blood tests.
How to prepare for the Vitamin B7 (Biotin) test
No fasting is required for this test. If you take a biotin or hair, skin and nails supplement, tell your doctor, as it can raise your level and affect other lab tests; some clinicians advise pausing high-dose biotin before certain investigations.
Understanding your Vitamin B7 (Biotin) results
Low biotin may reflect poor absorption or increased demand, while high levels usually indicate supplement use rather than a health problem. Your doctor-reviewed report arrives within 7 Days; review it with your physician, especially if other blood tests were taken at the same time.

A DHA-licensed nurse collects a small blood sample at your home, office or hotel across Dubai in around 20 minutes, and your report is reviewed by a doctor and sent within 7 Days.
No, fasting is not required for the Vitamin B7 test. You can eat and drink normally beforehand unless a separate fasting test is booked alongside it.
High-dose biotin supplements can falsely raise or lower thyroid, hormone and cardiac marker results. Declaring your biotin intake helps your doctor decide whether other tests need repeating.
Biotin supports keratin production, so genuine deficiency can cause hair and nail problems that improve once corrected. If your levels are already normal, extra biotin is unlikely to add benefit.
People with malabsorption disorders, those on long-term anti-seizure or antibiotic therapy, heavy raw-egg-white consumers and individuals with certain inherited enzyme conditions are more likely to run low.
Home lab tests in the UAE are self-pay, so the biotin test is billed in AED. You can pay online securely at the time of booking.
