Hcg Pregnancy Test Results

Hcg Pregnancy Test Results

What is the human chorionic gonadotropin (hCG) blood test?

The human chorionic gonadotropin (hCG) blood test measures the level of hCG hormone present in a sample of your blood.

hCG is produced during pregnancy. Your doctor may refer to the hCG blood test by another name, such as the:

  • beta-hCG blood test
  • quantitative blood pregnancy test
  • quantitative hCG blood test
  • quantitative serial beta-hCG test
  • repeat quantitative beta-hCG test

There are important differences between hCG blood tests and the hCG urine tests that you can purchase over the counter.

Urine tests can be influenced by factors such as dehydration and the time of day that you test, while an hCG blood test can provide conclusive results even in cases where hCG levels are quite low.

Why is the hCG blood test performed?

The hCG blood test is performed to:

  • confirm pregnancy
  • determine the approximate age of the fetus
  • diagnose an abnormal pregnancy, such as an ectopic pregnancy
  • diagnose a potential miscarriage
  • screen for Down syndrome

The hCG blood test is sometimes used to screen for pregnancy before you undergo certain medical treatments that could potentially harm a developing baby. Examples of these treatments include X-rays.

If an hCG test concludes that someone is pregnant, healthcare professionals can ensure that they’re protected and that the fetus isn’t harmed by those medical treatments.

What risks are associated with the hCG blood test?

Risks involved with having blood taken are minimal.

There may be a small amount of bruising where the needle was inserted. This can be minimized by applying pressure to the area for several minutes after the needle is removed.

 In very rare cases, the following may occur:

  • excessive bleeding
  • lightheadedness
  • fainting
  • hematoma, which happens when blood accumulates under your skin
  • infection at the needle site
  • swollen veins

What are the uses of the hCG urine test?

The hCG urine test confirms pregnancy about one to two weeks after your missed period. This is a qualitative test, which means that it will tell you whether or not it detects the hCG hormone in your urine. It’s not intended to reveal specific levels of the hormone. The presence of hCG in your urine is considered a positive sign of pregnancy.

Are there risks involved with this test?

The only risks associated with an hCG urine test involve getting a false-positive or false-negative result. A false-positive result indicates a pregnancy even though there isn’t one. Rarely, the test may detect abnormal, non-pregnancy tissue, which requires follow-up by a doctor. These results are rare because usually only pregnant women produce the hCG hormone.

There’s a higher risk of getting a false-negative result. If you get a false-negative result, in which case the test says you aren’t pregnant but you really are, you might not take the precautions necessary to give your unborn baby the best possible start. Such results may occur more commonly in early pregnancy or if the urine is too diluted to detect hCG.
