After a woman becomes pregnant with a baby, there will be significant changes in her body, especially in hormone levels, which will increase significantly. During pregnancy, the HCG in the pregnant woman's body may double every other day. When a woman undergoes a pregnancy test, it is to check the levels of hCG in her urine and blood. So, is it necessary to check for HCG in early pregnancy?
It is very necessary to check HCG in early pregnancy to determine whether the fetus is stable. If the HCG level in the pregnant woman's body is too low, it may lead to miscarriage. So women need to check for HCG in the early stages of pregnancy. If HCG levels are found to be too low, they should be replenished in a timely manner.
When pregnant women undergo HCG testing, venous blood is drawn for analysis. Because the level of HCG in the blood is not affected by food intake, there is no need to fast or hold urine before the examination. It is best for pregnant women to undergo the examination in the morning, as the results obtained from the examination are most accurate. At present, most HCG tests in hospitals are conducted using sandwich enzyme immunoassay, which has the advantages of high sensitivity, low cost, and fast detection.
Pregnant women should wear loose fitting clothes when going to the hospital for HCG examination, and not wear them too tight. It is best to allow the arm to be pulled out of the sleeve during the blood draw, which can avoid some trouble caused by the clothes compressing the blood vessels too tightly and help the blood draw proceed smoothly.
