QC Control Sets for GBS Testing Recalled Due to Contamination

Microbiologics QC sets used for GBS testing contain a negative control contaminated with Group B Streptococcus, causing test failures. Affects 541 units distributed nationwide.

What this means for you

Minor labeling or packaging issue, or a voluntary precautionary recall. Risk of harm is low but real — follow the manufacturer's instructions.

Our severity reasoning: FDA Class II medical device recall with no reported illnesses or injuries. The defect is a functional failure of a quality control reagent—the negative control tests positive for the organism it should test negative for—rather than a direct patient safety hazard. The impact is operational disruption requiring laboratory response.

Plain-English summary

Microbiologics Inc is recalling the Lactobacillus acidophilus negative control (item 0243) contained in QC Sets and Panels (KWIK-STIK Cepheid Xpert GBS QC Set catalog 8164 and Cepheid Smart GBS QC Set catalog 8165). The recall affects 541 units distributed nationwide.

The negative control was found to test positive for Group B Streptococcus (GBS) in some cases. Because this is a negative control, it should test negative for GBS. A positive result indicates contamination and causes the quality control validation to fail.

When the quality control test fails, laboratories cannot confirm that their GBS testing system is functioning correctly. This disruption may result in repeated testing or the need for alternative test methods. Laboratories should check lot numbers 8164-45 (12/16/2015), 8164-46 (12/16/2015), 8164-47 (09/02/2016), 8164-48 (09/02/2016), and 8164-49 (10/03/2016) against their inventory and contact their supplier or Microbiologics Inc if they have affected units.
