Please Read This If You Take Vitamin B-7

You may be aware that the way that Emergency Room doctors look for diagnostic evidence of a heart attack is to check the patient's troponin blood levels. Elevated readings indicate a heart attack. Active MC interferes with the absorption of "B" vitamins. So taking vitamin supplements after long-term disease activity is common.

Please be aware that if you take vitamin B-7 (biotin), it may affect tests for troponin. This is only an issue if you are being tested to determine whether or not you have had, or are having, a heart attack. But of course in that situation, accurate troponin enzyme test results are of paramount importance. Some labs have adjusted their tests to allow for B-7, but others have not. So if you should find yourself (or a loved one) being tested to identify a heart attack, please be sure to bring this to the ER doctor's attention if you (or another patient) have been taking biotin. Even if the lab does not consider biotin, at least the doctor will know how to interpret the results if he or she knows that biotin may be involved.
