Human chorionic gonadotropin (hCG) is a hormone produced by the placenta during pregnancy. hCG levels can be used to detect pregnancy and to monitor its progress. There are a few different ways to check hCG levels, including blood tests, urine tests, and saliva tests.
Blood tests are the most accurate way to measure hCG levels. They can be performed at a doctor’s office or a laboratory. Urine tests are less accurate than blood tests, but they are more convenient and can be done at home. Saliva tests are the least accurate type of hCG test, but they are also the least invasive.
