PREGNANCY TESTS (PREGNANCY TESTS)
Pregnancy starts from the moment when the sperm from a man fertilizes the egg cell that is thrown from the ovaries. The baby is called the embryo in the period up to the end of the 8th week and the fetus in the period from birth until the 8th birth.
The embryo begins to secrete into the embryo-surrounding cells from the moment the embryo is placed into the endometrium (5-6 days after fertilization), called the human chorionic gonadotropin (HCG). In pregnancy tests, it is the detection of this pregnancy hormone.
As the pregnancy progresses, the gradually increasing β-HCG starts to rise after a certain threshold level, and allows the pregnancy test to be positive in the urine. The pregnancy test performed by the Kandan also detects the amount of the adjacent B-HCG. For this reason, the blood test can detect the presence or absence of pregnancy without further delay. The urine test can never reach the reliability of the blood test. The probability of error is low when the presence of pregnancy in the urine test is detected; but if the absence is detected, it is necessary to repeat the test after a while considering the possibility of premature pregnancy. (In very early pregnancies, the urine test may not be able to show gestation, which may be very low for the blood test.)
The striking BETA-HCG hormone is a valuable test used in the detection and follow-up of conditions such as ectopic pregnancy, low molar pregnancy (also known as grape gestation), as well as being used to detect pregnancies not detected by the urine test or not visible by ultrasound.
