Hopefully after the first invalid, one or more of the collections was observed. If not order an immediate collection, unannounced and observed. None of these medications would be a known cause for an invaid, abnormal pH. What was the pH of the specimens that were obtained? If the collections were indeed observed, search previous years' postings on this wonderful forum. There are several threads that discuss consecutive invalids. Hope this helps.
