Preterm Labor
Diagnosis of Preterm Labor
A doctor's evaluation The diagnosis of preterm labor is usually obvious, based on the signs that labor is starting and the length of the pregnancy. Samples may be taken from the cervix, vagina, and anus to culture. Analysis of these samples may suggest a specific infection as the cause of preterm labor. A sample of urine may be analyzed and cultured (placed in conditions that encourage the growth of microorganisms) to check for kidney and bladder infections.
