How Is Ectopic Pregnancy Diagnosed?
In order to diagnose an ectopic pregnancy, the doctor will generally begin by asking a number of questions about:
- Current symptoms
- History of any medical conditions, including sexually transmitted diseases (STDs)
- Contraceptive use
- Current medications.
He or she will also perform a physical exam, looking for ectopic pregnancy symptoms. If the doctor suspects an ectopic pregnancy, he or she may recommend certain tests.
Tests Used to Diagnose Ectopic Pregnancy
Tests that may be recommended in order to help make a diagnosis include:
- Blood tests
- Ultrasound
- Culdocentesis
- Laparoscopy.
Blood Tests
The doctor may order several blood tests. Among others, it may include a test looking at hCG (human chorionic gonadotropin) levels in the blood. HCG levels that are low, that are not increasing at a normal rate, that have plateaued, or that are decreasing can indicate a possible ectopic pregnancy. Low progesterone levels may also be a sign of an ectopic pregnancy.
Ultrasound
A transvaginal ultrasound, along with a pregnancy blood test, often can confirm or rule out a diagnosis of ectopic pregnancy. Transvaginal ultrasound allows the doctor to see an extremely small gestational sac.
