Patients with preterm labor may be assessed for the presence or absence of lower genital tract infection.

  • Sterile speculum examination for ruptured membranes

  • Endocervical sampling for gonorrhea and chlamydia

  • Vaginal fluid pH

  • Wet smear for BV and trichomonal infection if indicated

  • GBS culture

  • Urinalysis and culture (if indicated)

Positive results are treated with appropriate antibiotics.
