High-dose biotin supplements can cause a multitude of false lab tests, masking recent heart attacks, pregnancies, or allergies, giving false signals about tumors, and far more. Here is what to do.

Great and informative article! I had only heard about the TSH test interference. But this is great to know for any future labs. The case of the girl having the surgery is tragic. Look at the dangerous conclusions people can jump to without sufficient knowledge and context of the individual's nutrition.
Also if you made a video on this, I bet it would get a lot of hits. I think on Youtube a lot of vloggers talk about biotin for the skin/hair benefits. But I'm certain they don't know about all these possible effects on their labs that could cause distress. "Taking biotin? Watch out for this!" Thumbnail is someone with nice hair but with a very panicked look on their face, haha.
Thank you! Good info. I’ve taken 10,000mcg daily for 10 yrs for thinning hair. It does seem to help. My ND said to stop biotin for 4 days before thyroid labs. No mention of any others. Now after reading this, I’m thinking a full week would be more accurate.
This essay is of major importance and is long overdue. It deserves wide dissemination to, well, any provider who gets labs for their patients. And as so many get their own labs these days... I suppose it would be optimal for all consumers of labs to read this work.

I will do my part to share the knowledge.
Thank You Chris!
Why do those of us on a carnivore diet need additional biotin when our ancestors did not?
Fantastic article Chris! Thank you so much for the countless hours you spend creating these very indepth and thoughtful commentaries.
Hi Chris. Do you offer consultation for food product development? If so would you please email me at dcampaudio@gmail.com? Thank you!
This is wild. I am in the medical field and only knew about its TSH lab effects.
Would you withhold lower dosages too such as 0.5 mg or would that be meaningless?
