When women go to the hospital to check if they are pregnant, the results can be obtained by examining the secretion level of human chorionic gonadotropin in the body, which can be checked by blood HCG test or urine test. So, what is the difference between blood HCG and urine HCG during this examination?
1. One of the obvious differences between using urine HCG and blood HCG for early pregnancy check after pregnancy is that the specimens collected for testing are different, which is the primary difference.
2. Secondly, although there are similarities in the purposefulness of the test results, there are also significant differences. The commonality is that the results obtained from urine or blood HCG testing can be used to diagnose early pregnancy. However, blood HCG testing can accurately diagnose abnormal pregnancy conditions such as multiple pregnancies, ectopic pregnancies, and developmental delays, combined with other clinical symptoms of pregnant women. Therefore, blood testing is often used for comprehensive diagnostic analysis of this type of pregnancy.
3. There are also differences in the testing time period. If urine HCG testing is required, it can only be performed 7-10 days after a woman shows signs of amenorrhea. When conducting a blood HCG test, it can be done about two days after a woman stops menstruating, which can provide more accurate results.
