why no tylenol before blood cultures drawn?

    We were just discussing why last night and everyone had a different reason and most just heard not to.

    We never give Tylenol, ASA, or antibiotics prior to blood cultures being drawn. I can only assume that those medications can someone how render the test invalid. I understand the antibiotic part. Hope this helps

    It is the somehow render the test invalid part that I am wondering about, how?

    Blood cultures are done to put blood in a petre dish to see if a particular strain of bacteria will growth. Antibiotics kill bacteria.

    TYLENOL IS NOT A ANTIBIOTIC...WHAT TYLENOL DOES IS SURPRESS THE STRAIN WHICH MAY NOT FULLY GROW OUT ON THE DISH, AND THEREFORE THE SENSITIVITY COULD BE INACCURATE.

    This is how our debate started last night. Tylenol does not suppress growth, the temperature our body runs is in defense against bacteria, I just dont get how tylenol wouldn interfere on a cellular level.

    To my knowledge, Tylenol has no effect on bacterial growth or the accuracy of blood cultures. My guess would be that giving Tylenol or other antipyretics prior to drawing a blood culture might obscure the clinical picture. Perhaps the practitioner wants an accurate temp to correlate with other physical signs and symptoms of infection, along with blood culture results.

    I've never seen or heard to hold Tylenol until blood cultures are done-until tonight. Antibiotics, yes-we frequently get orders to wait on infusing antibiotics until after the blood cultures are done.

    If a patient is for some reason immuno suppressed the body's only defense against the bug (bacteria or viral) is a fever. I am assuming the doc wanted the cultures drawn before the tylenol and ATBX to get the true cultures before anything could ulter with the results. I know tylenol does not fight against bacteria and/or viral invasion, but if you just treat the fever you may never know the true source.
    Thus drawing cultures first then medicating is a valid pratice. We do it all the time, of course after the cultures the tylenol and ATBX are usually given in a timely fashion.

    I've never heard of holding Tylenol until after cx are done--I don't understand how treating the fever would interfere with finding the source?
