When you need to donate blood for pregnancy
Early pregnancy diagnosis method - a blood test for hCG. It is a hormone of pregnancy, which indicates the presence of a woman's body chorionic tissue (ie, embryonic tissue lobe). According to its value determined by the duration of pregnancy.
A blood test for human chorionic gonadotropin shows the presence of hormone, which allocates additional membranes or layers that appear in the uterus after conception. The hormone may be present in the body is not a pregnant woman (after the abortion it may be detected in the blood of 5-6 days) or men (for cancer of the testicles). Women pass the test for hCG in a few cases: in the absence of menstruation, when the threat of miscarriage or non-viable pregnancy, for prenatal diagnosis of fetal malformations, etc. The analysis also indicated for the evaluation of the completeness of abortion. The diagnostic value of analysis in early pregnancy is justified - in this period, no pregnancy test or ultrasound can not accurately determine whether fertilization has occurred ovary. The level of hCG can judge the pregnancy - for each week of the standard value is defined. To perform the analysis on human chorionic gonadotropin is necessary to take blood from a vein. This is best done on an empty stomach early in the morning. If you have to take the analysis at a different time of the day, it is necessary to sustain a break of 6 hours after you last ate loosely. If at this time you are taking any medication drugs, especially hormonal drugs, you should inform your doctor. Getting results is usually delayed for two or three days, but you can try to negotiate in the laboratory and to pay urgent diagnosis. recommended blood test for pregnancy is not earlier than the third or fifth day of menstruation. You can check the result, repeat the test after two or three days - in the early months of pregnancy hCG level in the blood increases each day and reaches its peak in week 11, so the number of indicators can reliably confirm a pregnancy. After that, you must visit a gynecologist, and a few weeks later to make the first ultrasound. There are home pregnancy tests to determine the level of hCG in the urine. But the reliability of these tests is much lower, as the necessary concentration in the urine of the hormone accumulates at a later date.
