Is Vit A blood test worth taking?
#1 · November 30, 2021, 12:12 am
I understand that it is not reliable and Grant himself said that it wasn't the tool for detecting vit A toxicity. However, in some studies and people serum vit A did turn out to be elevated. All in all, shall I do it just to maybe make sure I'm on the right track? Thanks!

One single test is probably useless but when you retest so you can see what is doing that number over time. Then it is good info.. This is True basically for all blood test markers. So ideally once a year full blood test. So you can se what and how is changing over the years...
