Sign in to monitor this recall

Summary

TECHNO-PATH MANUFACTURING LTD. is recalling 127 units of Multichem ID-B Positive Control (Model SR103B) because the HBsAg analyte may show negative recovery when used on Alinity i laboratory testing platforms. This product is used in laboratories as a quality control serum to ensure that tests for diseases such as HIV, Hepatitis B and C, and Syphilis are functioning accurately. If the control does not perform correctly, laboratory staff may not realize that their testing system is failing to detect the virus.

The defect may result in incorrect laboratory quality control measurements for Hepatitis B surface antigen (HBsAg). This poses a risk of clinicians relying on inaccurate laboratory data, potentially leading to missed diagnoses or incorrect patient management.
