Tennessee rates for HCPCS 81225

A blood or cheek-swab test that examines common variations in the CYP2C19 gene, which controls one of the liver enzymes that break medicines down. The result predicts whether a person clears certain drugs quickly, normally, or slowly, so a prescriber can pick a suitable medicine or adjust the dose. Clopidogrel, several antidepressants, and some acid-reducing medicines depend on this enzyme.
