What is it indicated for?

The FemExam® TestCard™ contains two qualitative, colorimetric tests for use in the characterization of a vaginal fluid sample: (1) a pH test that differentiates vaginal fluid pH less than pH 4.7 from vaginal fluid pH equal to or greater than pH 4.7; and (2) a test that detects alkali volatilizable amines in vaginal fluid.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
