  1. Pankaj Kumar Singh says:

    Question no.8 explanation- AP test is preliminary test not confirmatory test.

    1. AP test (specifically AP isoenzyme test) is highly (more specific than crystals test) specific to semen because it depends on the detection of seminal acid phosphatase [SAP] and it doesn’t have to do with infertility in males. So, if the semen discharge where spermatozoa are absent due to oligospermia (very low sperm count), azoospermia, (complete absent), and vasectomized individuals, they still can be detected with the AP isoenzyme test. And AP spot test is also more specific than both of the microcrystal tests.

  2. Pankaj Kumar Singh says:

    Que 8. Crystal test is confirmatory like barberio test and Florence test. That’s why correct sequence is also wrong.

    1. Hi Pankaj, Crystal’s test for blood is a confirmatory test but for a semen sample, the crystal test is a presumptive/screening test because they are based on the detection of choline(Florence test) and spermine (Barberio test) and their detection only give 70% and 26% of a positive result, respectively.
