Group A Strep Antigen Test, Laboratory Immunoassay

Michigan rates for HCPCS 87430

Checks a throat swab for proteins from group A streptococcus, the bacterium behind strep throat, using an instrument-read laboratory immunoassay. It is the laboratory version of the test rather than the strip read by eye during an office visit. Results generally come back the same day, so a decision about antibiotics need not wait for a culture to grow.
