Test Procedure

gb one x

  • Place the rectal/vaginal swab into a selective enrichment LIM broth and incubate for 18-24 hours at 35-37 C.
  • Transfer 15µL of specimen into the provided Sample Buffer Tube (SBT).
  • Vortex the SBT at high speed for 15 seconds.
  • Unseal the pouch containing the Revogene® GBS LB PIE.

gb two x

  • Using the Disposable Transfer Tool (DTT), aspirate the Sample Buffer (SB) by squeezing the entire bulb until the liquid level is anywhere between the two lines on the DTT.
  • Discharge the specimen completely into the Sample Loading Chamber of the PIE.
  • Close the cap of the Sample Loading Chamber tightly.

gb three x

  • Start the test run by navigating to the menu. Select Revogene® GBS LB. Follow the onscreen instructions to load the patient test PIE.
  • Load the remaining patient tests. If less than eight (8) PIEs are being tested, load MOCK PIES in the carousel in the remaining positions.
  • Scan the retention ring and place it on the carousel

gb four x

  • Close the instrument lid with both hands and ensure the lid lock engages.
  • Select to initiate the test and walk away.
  • The lid opens when the run is complete.
  • Remove all PIEs including MOCK PIES after the run.
  • Tap the icon to see test results.

“Our laboratory participated in the clinical validation of this GBS LB assay. The assay had high sensitivity and specificity. The system was easy-to-use and provided the results up to 18h faster than standard culture.”
