Platelia anti-SARS-CoV-2 S IgG Quant Assay
This is an immunoassay for the quantitative determination (BAU/mL) of anti-spike IgG antibodies to SARS-CoV-2. Clinicians are able to identify individuals with an adaptive immune response to SARS-CoV-2 following SARS-CoV-2 infection or COVID-19 vaccination with vaccines that specifically generate anti-S immune responses. This test is CE-marked.

Coronavirus Ag Rapid Test Cassette (Swab)
Our Coronavirus Ag Rapid Test is a quick and easy tool for the qualitative detection of nucleocapsid protein antigen from SARS-CoV-2 in nasal or nasopharyngeal swab specimens for the diagnosis of COVID-19 infection. For COVID-19 diagnosis and confirmation, Bio-Rad offers a 15-minute SARS-CoV-2 antigen test for rapidly diagnosing patients in laboratory and point-of-care settings. A complementary Control Swabs Kit can be used to validate new test kits, lots, and operators.

Platelia SARS-CoV-2 Total Ab Assay
This assay detects total anti-nucleocapsid antibodies (IgM, IgA, and IgG) to SARS-CoV-2 with high sensitivity (92% sensitivity for patients tested ≤8 days after symptom onset and 100% for patients tested >8 days after symptom onset). This blood-based immunoassay, designed for in vitro diagnostic testing, is the first serology assay with U.S. Emergency Use Authorization to test for total antibodies in a single assay. The test has also met requirements for applying the CE-mark in Europe.

VIROTROL SARS-CoV-2 and VIROCLEAR SARS-CoV-2 for SARS-CoV-2 Antibody Lab Testing
To ensure an unbiased independent assessment of a laboratory's test systems, we offer VIROTROL and VIROCLEAR SARS-CoV-2 antibody controls. These ready-to-use, liquid controls are formulated from human plasma to test on total IgG/IgM and IgG antibody assays. VIROTROL and VIROCLEAR SARS-CoV-2 are available in three separate classes specifically designed to challenge the assay cutoff of a broad range of methodologies. Laboratories can achieve greater confidence in patient test results by running independent SARS-CoV-2 quality controls with their SARS-CoV-2 antibody assays.
