can ectopic pregnancy be detected in blood test?

A pelvic exam can help your doctor identify areas of pain, tenderness, or a mass in the fallopian tube or ovary. However, your doctor can't diagnose an ectopic pregnancy by examining you. You'll need blood tests and an ultrasound.

If you've had a tubal ligation and you miss a period or get a positive result from a pregnancy test, see your doctor right away. Because you're at a higher risk of a serious medical condition called an ectopic pregnancy, which happens when a fertilized egg attaches outside the uterus, instead of inside.

IUI probably doesn't increase the risk of ectopic pregnancy, but all women having fertility treatment need to be aware of the possibility of ectopic pregnancy. We can usually detect an ectopic pregnancy by the level of hCG in the pregnancy test and an early ultrasound scan, but not always.

In 95% of ectopic pregnancy cases, a good transvaginal ultrasound examination can actually see the ectopic pregnancy in the Fallopian tube. However occasionally the ectopic pregnancy is too small to be detected with ultrasound examination.

Diagnosis of ectopic pregnancy Your GP will ask about your symptoms and medical history, and examine you. They'll offer you a pregnancy test. If your pregnancy test is negative, it's unlikely that your symptoms are being caused by an ectopic pregnancy.

An ectopic pregnancy can be a very serious, and even life-threatening, condition. Levels of hCG remain low during an ectopic pregnancy.

A pregnancy that's ectopic is usually diagnosed at about four to six weeks into pregnancy, typically through an ultrasound and blood tests to check the level of the hormone human chorionic gonadotropin (hCG). A lower-than-normal increase in hGC levels may indicate an ectopic pregnancy.

According to the literature, a negative pregnancy test via urine or low β-hCG in serum of pregnant women is 3.1% and 2.6% respectively in ectopic pregnancies8-10. In addition, more than 1% of ectopic pregnancies are associated with undetectable levels of β-hCG.

A pregnancy test can detect hCG levels within 10 days of a missed period, and some tests can detect it even earlier, within a week of conception. A negative pregnancy test does not absolutely rule out pregnancy or ectopic pregnancy; it may simply be too early to detect hCG in the mother's urine or blood.

Ultrasound for Diagnosis But frequently the sac will never be visible at all on ultrasound in a tubal pregnancy. A transvaginal ultrasound showing no gestational sac with an hCG level above 1,500 is considered fairly certain evidence of an ectopic pregnancy.

A missed or late period However, the fact that you may experience normal pregnancy symptoms, such as nausea, painful breasts or a swollen abdomen but no bleeding or pain, does not completely rule out an ectopic pregnancy, although this is rare. A true period should be normal flow and duration for you.

Would an Ectopic Pregnancy Show Up on a Home Pregnancy Test? Since ectopic pregnancies still produce the hormone hCG, they'll register as a positive home pregnancy test. Women with ectopic pregnancies will also experience early pregnancy symptoms like sore breasts, nausea, spotting, and more.

Levels of this hormone increase during pregnancy. This blood test may be repeated every few days until ultrasound testing can confirm or rule out an ectopic pregnancy — usually about five to six weeks after conception.

— Ectopic pregnancy is diagnosed if the ultrasound detects a fetal heart beat or an embryo that is outside of the uterus. Since ectopic pregnancies may not be detected by ultrasound, the hCG level is also measured.

Diagnosis of ectopic pregnancy If your pregnancy test is negative, it's unlikely that your symptoms are being caused by an ectopic pregnancy.

In the case of an ectopic pregnancy, the fertilized egg doesn't attach to the uterus. Instead, it may attach to the fallopian tube, abdominal cavity, or cervix. While a pregnancy test may reveal a woman is pregnant, a fertilized egg can't properly grow anywhere other than the uterus.

An ectopic pregnancy is likely if there are no signs of an embryo or fetus in the uterus as expected, but hCG levels are elevated or rising.
