What this means for you
Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.
Our severity reasoning: Scored 3 under the risk-of-harm criterion: a quality control that fails to recover its analyte can mask a testing problem, and no injuries are reported.
Plain-English summary
Multichem ID-B, model SR103B, is being recalled. The product is intended for use as an unassayed positive qualitative quality control serum to monitor the precision of laboratory testing procedures for determinations including anti-HIV-1 IgG, anti-HBc IgG and anti-HTLV-I IgG.
The firm identifies the potential of negative recovery of the HBsAg analyte across two lots of Multichem ID-B Positive Control when tested on the Alinity i platform.

The product was distributed in California, Colorado, Connecticut, Florida, Hawaii, Illinois, Louisiana, Michigan, Minnesota, Nevada, New York, Oregon, South Carolina, Tennessee, Texas, Wisconsin and Wyoming.
