Vaginal/rectal OB Strep PCR
Vaginal/rectal OB Strep PCR-14203
Currently, the standard of care for preventing neonatal GBS disease is screening pregnant women at 35–37 weeks of gestation to determine their GBS colonization status. Assay is a qualitative in vitro diagnostic test designed to detect Group B Streptococcus (GBS) DNA from enriched vaginal/rectal swab specimens

1. Wipe away excessive amounts of secretion or discharge from the vaginal/rectal area. Use of gel or lubricant before collection or failure to remove excessive secretions or discharge may cause the test to abort and require recollection of the specimen. 2. Remove swab from the transport system. 3. Carefully insert the swab into the patient’s vagina. Sample secretions from the mucosa of the lower one-third part of the vagina. Rotate the swab three times to ensure uniform sample on the swab. 4. Using the same swab, carefully insert swab approximately 2.5 cm beyond the anal sphincter, and gently rotate to sample anal crypts. 5. Place swab in the transport container. 6.
