Human Chorionic Gonadotropin (β-HCG) Blood Test by Homogeneous Fluorescence Analyzer
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.
What is human chorionic gonadotropin (hCG)?
During pregnancy, cells in the developing placenta make hCG. The placenta is the sac that nourishes the egg after it’s fertilized and attaches to the uterine wall.
hCG can first be detected in a blood sample about 11 days after conception. Levels of hCG continue to double every 48 to 72 hours. They reach their peak around 8 to 11 weeks after conception.
hCG levels then decline and level off, remaining steady for the rest of the pregnancy.
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.
How is the hCG blood test performed?
The quantitative test measures the level of hCG hormone in a blood sample.
A healthcare professional takes a blood sample by following these steps:
- An elastic band is wrapped around your upper arm to stop the blood flow and to make the veins in your arm more visible. This is so the needle can be inserted easier.
- A vein is located and the skin around the vein is cleaned with alcohol.
- The needle is inserted into the vein and a tube is attached to the end of the needle to collect the blood.
- After enough blood is collected, the elastic band is removed from your arm.
- As the needle is removed, cotton or gauze is placed onto the puncture site.
- Pressure is applied to the cotton or gauze, and it’s secured with a bandage.
While the needle is being inserted, you may feel a brief stinging or pinching sensation, or you may not feel anything at all.
When the needle is in the vein, you may feel minor discomfort or stinging. Afterward, you may experience some mild throbbing at the puncture site.
After your hCG levels have been measured in the blood sample, the results are sent to your doctor. They may request an appointment with you to discuss the results of the test.
No particular preparation is required for the hCG blood test.
