I cut my nail sample last week but I didn’t ship them because I thought my doctor was going to provide a test. Never happened.
Is there any isssue with testing nails that have not been recently cut from the toes? Btw, for future reference, can one 100mg sample be enough for mineral testing AND hormone testing, or would that require net-new sample?
Thanks!
For mineral testing, the age of nails probably does not matter much, at least for a few months. It's just that you'd have to add that additional time to the ~3 month lag in terms of what the results map to - i.e. if you give us nails that were cut 2 months ago then the results would show mineral status 5 (3+2) months ago.
As far as sufficient material for both mineral and steroid testing - I'd say 150mg+ are preferable to account for losses during sample processing. Those losses can be extensive for the steroid analysis portion so more material reduces the risk of not having enough sample and thus producing unreliable results.
