Exagen's lab test, called Avise PG, will be used to measure whether patients are receiving an appropriate dose of MTX. Avise PG measures MTX polyglutamate levels, the active metabolites of MTX. Medco Research Institute will work with Medco clients to recruit patients to take part in the pilot program.

 

When a volunteer receives an initial MTX prescription for RA, Medco will provide the prescribing physician with the Avise PG test, and patients will be alerted that a blood-
