Pregnancy Test (hCG Quantitative)
When you’re expecting, an hCG pregnancy blood test will help you know for sure.
This test provides an accurate measurement of the amount of Human Chorionic Gonadotropin (hCG) present in your blood. HCG may appear in the blood of pregnant women about 10 days after conception. This pregnancy blood test is more accurate and can detect pregnancy earlier than other home pregnancy tests.2
Under the care of your healthcare provider, this hCG pregnancy blood test may also be used to help identify an ectopic (tubal) pregnancy, evaluate an at-risk pregnancy, or confirm a woman is not pregnant before pursuing medical treatments that could negatively impact a developing fetus.1
As with urine/home pregnancy tests, it is possible to receive false results (both negative and positive) from a blood pregnancy test.
False Negative Results (test is negative, but you are pregnant): usually occur if the blood pregnancy test was performed too early (a rule of thumb is that it takes about 10 days after conception for the test to show a positive result). A negative result may be attributed to not enough hCG in the blood to detect a pregnancy. Your hCG levels rise very quickly during early pregnancy. If you believe that you received a false negative result because you tested too soon and you still have not had a menstrual period, you may repeat the beta hCG quantitative test again after waiting 48 to 72 hours.2
False Positive Results (test is positive, but you are not pregnant): very rarely happens. You may get this result if you are taking a medication that contains hCG or due to certain medical issues.2
No special preparation.
