Im getting a blood test done this coming monday to find out what is causing my symptoms. Right now im relying on anti histamines to get through the day. im just wondering as to taking an antihistamine before the blood test could compromise the results? one web site i found did say it will not affect the results but id still like to confirm. can anyone confirm?

Is this for allergy testing? If so, it sounds plausible that it could affect your results. Can you call the doc today to confirm whether you can or not?
