Pregnancy and childbirth are very important things for women. When preparing for pregnancy, if menstrual delay is found, relevant early pregnancy tests can be conducted, which can be checked through blood HCG and urine HCG. Some women want more accurate testing, so which one is more accurate, blood HCG or urine HCG?
Blood HCG is more accurate. During pregnancy, hCG is secreted by the trophoblast layer of the placenta. HCG is secreted into the bloodstream and metabolized into urine. The concentration of hCG in the blood is higher than that in the urine. Therefore, the results of blood sample testing for hCG are more accurate than those of urine testing. Routine examination is best conducted 20 days after sexual intercourse or 7 days after menstrual delay.
Compared to blood HCG test. Urine tests can sometimes be influenced by other factors, such as other hormones, such as LH hormone, which may react with the test strip, leading to false positives. Thyroid hormones may also affect it. So overall, diaper testing has more interference than blood HCG testing.
Worried about getting pregnant, early pregnancy testing can be done about 10 days after the delay of menstruation, usually with early pregnancy test strips. If the test shows pregnancy, you can go to the hospital again for blood HCG testing. This will be relatively more accurate, and attention should be paid to the correct use of early pregnancy test strips, with morning urine testing as the main focus. If you are concerned about the accuracy of observation during one test, you can conduct multiple tests for observation.
