    C & S question / oddity

    I had a C&S done, positive for kleb., but there was no sensitivity test for levofloxacin (although there was for cipro). Then I was prescribed levofloxacin anyway.

    Why would such a test omit the levofloxacin result? Isn't that one of the most common things one would want to know? Especially as I had been on levofloxacin before.

    Weirder, the same test six months ago from the same office included both cipro and levofloxacin results.

    Can anyone explain this? Should I be worried? I'm not getting great results from the levofloxacin so far either.

    If I'm not mistaken, isn't Levo the one that leads to tendon problems?

    They're both quinolones, if the bacteria is sensitive to cipro it will be to Levaquin. Was the bacteria rated sensitive to cipro, and not intermediate? Yes, the quinolones can lead to tendon rupture, though I never experienced any despite several 90 day courses of cipro.

    Either it is important to test both Cipro and levo, or it is not important to do so.

    • If it is important, why omit the levo rating from the later C&S report?
    • If it is not important, why include both results in the earlier C&S report?


    Anyway, isn't "sensitivity" not just "yes or no" but rather a numeric indication of strength? I mean, two drugs might be both be graded "sensitive", but if drug A has a sensitivity value of 4 and drug B of .5, then drug B is 8 times more powerful. Thus, even if the cipro sensitivity implied levo sensitivity, maybe the levo would still be less sensitive than the cipro, and so maybe, had the results been available, a decision to use cipro, not levo, would have been made, right?

    It was rated sensitive.

    The test is for both and either or can be prescribed. If the organism is sensitive to levofloxin it is sensitivy to ciprofloxin.
