The pelvic structures or fetus are normal.

Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.

An abnormal result may be due to many conditions. Some problems that may be seen include:

• Birth defects
• Cancers of the uterus, ovaries, vagina, and other pelvic structures
• Infection, including pelvic inflammatory disease
• Non-cancerous growths of the uterus and ovaries (such as cysts or fibroids)
• Twisting of the ovaries

Some problems or conditions that may be found specifically in pregnant women include:

• Ectopic pregnancy
• More than one fetus (twins, triplets, etc.)
• Miscarriage
• Placenta previa
• Placental abruption
• Shortened cervix, which increases the risk for preterm delivery or late miscarriage
• Tumors of pregnancy including gestational trophoblastic disease
