CHICAGO -- The placental alpha-microglobulin-1 test is superior from a cost-benefit perspective to the combined traditional diagnostic test of pooling, nitrazine
, and ferning for screening in the setting of questionable preterm premature rupture of membranes, Dr.
I prepared the equipment I needed for the three part assessment (pooling, Nitrazine
This is important because a number of POC tests are not always recognized as "tests" by clinicians (eg, hemoccult, nitrazine
pH, provider-performed microscopy).
Premature rupture of membranes was confirmed by vaginal pooling, a positive Nitrazine
test and amniotic fluid arborization.
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.
