The test may help show if you will deliver early or not.If you have preterm labor, you will need to be in the hospital. You may receive medicines to stop your contractions and mature your baby's lungs.Open ReferencesReferencesHN, Romero R. Preterm labor and birth. In: Landon MB, Galan HL, Jauniaux ERM, et al, eds.
