This new lateral flow immunochromatographic test offers enhanced sensitivity through the detection of Trichomonas antigen as opposed to the traditional wet prep method, which relied on the labor intensive microscopic visualization of motile Trichomonas trophozoites. Because this new assay detects antigen as opposed to viable organism, specimen stability is also extended. When collected with a single eSwab™, specimens are stable for up to 24 hours at ambient temperature and 36 hours when refrigerated. Swabs collected for the wet prep method were only stable for 3-5 hours, so there is no longer a need for STAT delivery to the laboratory.
In the College of American Pathologists publication CAP Today the question was asked, “Are there regulations guiding the practice of taking additional blood samples from a patient (in case additional testing is needed later) even though there are no orders for the blood samples?” The limited literature on this topic has shown that inpatients (in those studies) have had up to 700 mL of blood collected during hospital stays. Thus we have to step back and ask: Does that make sense?
