CPT code 86318 is used to describe a COVID-19 antibody test that uses a single step method immunoassay. This test detects antibodies in the blood, which are produced by the body in response to a COVID-19 infection. This code can be used for both qualitative and quantitative antibody testing.
CPT code 86328 is used to describe a COVID-19 antibody test that uses a multiple-step method immunoassay. This test also detects antibodies in the blood, and can be used for both qualitative and quantitative antibody testing. The multiple-step method may involve more than one step, such as an initial screening test followed by a confirmatory test.
CPT code 86769 is used to describe a COVID-19 antibody test that uses a neutralization assay. This test is a type of confirmatory test that detects the presence of neutralizing antibodies, which are a specific type of antibody that can prevent viral infections. Neutralizing antibodies are often considered to be more important than other types of antibodies for protection against COVID-19.
