A Placental Alpha Microglobulin-1 Immunoassay is a qualitative test intended to detect the presence of placental alpha microglobulin 1 (PAMG-1) in cervicovaginal secretions. The test is indicated as an aid to assess the risk of spontaneous preterm delivery in less than or equal to 7 days from the time of cervicovaginal sample collection in pregnant women with signs and symptoms of early preterm labor.
