This is important because a number of POC tests are not always recognized as "tests" by clinicians (eg, hemoccult, nitrazine pH, provider-performed microscopy).

Nurse O'Connor performed a nitrazine test and confirmed the presence of amniotic fluid, a sign that the patient could have had premature rupture of membranes.
Cooper's method was slightly more accurate than the 93% rate of nitrazine strip testing, in which false positives can result from specimen contamination with urine, blood, semen, or vaginal discharges caused by infection.
