New Orderable: Gram stain for BV and Yeast

The new orderable for the Gram stain for BV and yeast is available

The Gram stain for bacterial vaginosis (BV) and yeast is considered the gold standard for the diagnosis of various vaginal infections. The Gram stain utilizes the Nugent scoring method to evaluate the ratios of Lactobacillus, Gardnerella vaginalis, Mobiluncus, and Atopobium vaginae. Accurate diagnosis of BV relies upon both the increase in abundance of specific urogenital pathogens (such as Gardnerella) as well as the concordant decrease in the amount of otherwise protective “usual flora” (Lactobacillus). In addition to scoring the abundance of these organisms, the Gram stain may also be used to quantify yeast making suspected contributions to BV. Continue Reading

FIT (Fecal Immunochemical Test) Reminder

In March of 2015, the Microbiology department announced new testing for Occult Blood Stool. We now offer Occult Blood, Immunoassay, Screening (Test #4315, Epic #LAB3110) and Occult Blood Immunoassay, Diagnostic (Test #4316, Epic #LAB3093) using the Hemosure® one-step iFOB Test. This technology has improved specificity, sensitivity, accuracy and cost-effectiveness. This test replaced the Guaiac-based test as the recommended test.

The specimen requirements are a sterile container, so patients will no longer be mailing or dropping off cards. Guaiac-based testing is still available but cards are no longer supplied.

Please review this Orderable Spotlight for more information.
