“Microbiologics HPV Control Panel Recall: Low HPV 16 L1 Concentration Causes Invalid Test.” GovInfoNow, updated August 18, 2026. https://govinfonow.com/recall/53059-microbiologics-hpv-control-panel-recall-low-hpv-16-l1-concentration. Based on FDA recall #Z-1163-2025 (https://api.fda.gov/device/enforcement.json?search=recall_number:%22Z-1163-2025%22&limit=1).

The FDA announced on Jan. 20, 2025, that Microbiologics Inc is recalling its Multi-Strain Human Papillomavirus (HPV) Control Panel due to internal quality control failures. The hazard involves potential invalid results or no detection of HPV 16 L1 in some instruments and assays.

How to tell if you have it

  • Brand: Microbiologics
  • Product: Multi-Strain Human Papillomavirus (HPV) Control Panel (Inactivated Pellet), REF 8234; in-vitro
  • UDI/DI: 70845357043077
  • Lot Number: 8234-22
  • Quantity: 16 units

The hazard

Internal quality control procedures were not followed correctly for the testing and release of three lots of REF 8234/8235, resulting in the release of products that should have failed. The concentration of one target (HPV 16 L1) was low enough to cause QC failures, no detection, or invalid results on some instruments and assays.
