Does biotin affect liver function tests?

My son takes biotin for his hair and before his routine blood checkup last month, the doctor told him to stop taking it for three days. He said these vitamin pills can sometimes interfere with the lab machines and show wrong reports, even if your liver is completely fine. It is always better to be safe and ask your doctor.

Please don't assume any abnormal liver test is just because of biotin and ignore it. I once ignored some minor digestive issues thinking it was just gas, and it turned out to be a fatty liver issue that required proper treatment. If your liver reports are off, show them to a gastroenterologist immediately to rule out any actual condition.

This is a very common issue that many people don't know about. Biotin is widely used in lab testing assays, so having high levels of it in your blood can cause false high or low readings in liver and heart tests. Just stop taking your biotin supplement for at least 72 hours before your blood draw, and you will get accurate results.

Oh, I panicked so much last year when my liver enzymes showed slightly abnormal levels in a routine test. My doctor asked if I was taking any beauty supplements, and I was taking high-dose biotin for hair growth. He made me stop it for a week and re-do the test, and everything came back completely normal! It was just a lab interference.

I go for blood tests every six months to monitor my BP and kidney function. My doctor strictly told me to disclose every single vitamin and biotin supplement I take, as they can alter the lab readings. It doesn't actually damage your liver, but it can make the test reports look incorrect, which can cause unnecessary worry.
