On February 8, 2022, BioRad issued a voluntary recall for the RPR portion of the BioPlex 2200 Syphilis Total & RPR Test Kit. The U.S. Food and Drug Administration (FDA) classified this as a Class 2 Device Recall on March 16, 2022.

Individuals who need syphilis testing should continue to get tested and receive the full testing algorithm.
