Bio-Rad Laboratories announces the launch of Exact Diagnostics GBS Positive and Negative Run Controls to complement the previously launched Exact Diagnostics GBS Verification and Validation Panel. These ready-to-use independent quality controls are for use with Group B Streptococcus (GBS) molecular assays with applications such as the routine evaluation of assay performance and the testing of operator proficiency. With the positive control containing whole, intact, heat-inactivated GBS bacteria at a challenging concentration level to simulate a low positive clinical specimen, the negative control containing human cells to mimic adequate specimen sampling, and both controls formulated in Lim broth matrix, the controls simulate patient specimens after enrichment. Therefore, they monitor the entire workflow of molecular assays including extraction, amplification, and detection, while accounting for the matrix effect.
