Human chorionic gonadotropin 2. 1 Are you pregnant? If the same room is pregnant, then the human chorionic gonadotropin will rise beyond the reference range, and the reference range of each hospital is different, but generally more than ten can be diagnosed as pregnancy! So the HCG result is 2. 1, which can confirm that she is not pregnant.
Hcg is a glycoprotein secreted by placental trophoblast cells. In general, placental syncytiotrophoblast cells will produce a large amount of human chorionic gonadotropin after pregnancy. It consists of glycoproteins of α and β dimers. The α subunit is basically similar to follicle stimulating hormone, luteinizing hormone and thyroid stimulating hormone secreted by pituitary gland, so it can cross-react with each other, while the β subunit has different structures. What does βhcg mean? βhcg is a component of hcg.
After conception, the increase of βhcg in bleeding can be detected from the 9th-11day after fertilization, and the amount of βhcg can be increased twice every two days thereafter. The first 8 weeks of pregnancy increased rapidly to maintain pregnancy. At about 8 weeks of pregnancy, hcg gradually decreased until it reached relative stability at about 20 weeks.
The radioimmunoassay value of β-HCG in normal people is generally less than 3. 1. If it exceeds 5, the possibility of pregnancy can be considered; if it exceeds 10, pregnancy can be basically confirmed.
As hcg is a specific hormone secreted during pregnancy, βhcg can be used to assist in the diagnosis of early unruptured ectopic pregnancy. The amount of hcg secreted by normal villi is very large, and the titer of HCG is rising rapidly every day, rising by more than 66% every 48 hours. If βhcg rises above 66% every two days, it can be diagnosed as intrauterine pregnancy. If the increase is less than 66%, it is likely to be ectopic pregnancy or intrauterine pregnancy dysplasia.
For urine hcg, many women will use early pregnancy test paper to test themselves at home. Generally speaking, urine hcg test such as early pregnancy test paper can generally be tested one week after menopause, while blood HCG early pregnancy test can often be tested one or two days after menopause. The detection time of blood hcg can be earlier, and the detection value is more accurate and the error is smaller than that of traditional urine hcg detection. Blood hcg detection is more accurate and sensitive to pregnancy reaction, and the accuracy rate is as high as 99%. In addition, detecting blood hcg is helpful to judge ectopic pregnancy, multiple pregnancy, abnormal embryonic development, hydatidiform mole, some endocrine diseases or tumors.
What does urine hcg mean? Urinary hcg is human chorionic gonadotropin in human urine. After a woman is pregnant, the human chorionic gonadotropin in blood and urine will increase greatly.
Test urine hcg. If the result is positive, you should be pregnant. If the result is negative, you are not pregnant. Some test results will have numerical reference. Urine HCG 5000IU/L, 60-70 days pregnant > (8-32) ×104 iu/l.
Women often use early pregnancy test paper when doing pregnancy self-test at home. Early pregnancy test paper mainly detects HCG hormone in urine. There are still many errors in the detection accuracy of early pregnancy test paper. Without professional guidance, the general test results can only reach 75% accuracy. If the test is carried out under the guidance of a doctor, the correct use of early pregnancy test paper can be guaranteed, and the detection accuracy will be higher at most.
Although a variety of early pregnancy test papers show that women can do pregnancy self-test after missing normal menstruation 1 day, in fact, not all pregnant women excrete HCG hormone at the same speed and time. In general, the secretion of syncytial trophoblast will lead to the increase of HCG hormone in urine after 6 days of pregnancy. Therefore, if your menstruation is normal, it is necessary to make sure that the pregnancy test is obviously menopause for more than 7 days.
What is the normal value of hcg?
For the examination of hcg, we usually judge whether we are pregnant by detecting the content of hcg in blood or urine. The hcg values are different before and after pregnancy and at different stages of pregnancy. What does normal hcg mean? Normal value of hcg generally refers to the range value of hcg when not pregnant. The value of hcg is divided into two ranges according to pregnancy and non-pregnancy, so some people call the normal value of hcg in non-pregnancy and normal value of hcg after pregnancy as normal value of hcg.
Normal value of hcg in peripheral blood of non-pregnant women
The radioimmunoassay value of β-HCG in normal people is generally less than 3. 1. If it exceeds 5, the possibility of pregnancy can be considered; if it exceeds 10, pregnancy can be basically confirmed.
The absolute value of hcg in blood varies greatly between different stages of pregnancy and pregnant women, and the value will change greatly in different stages of pregnancy. After 35-50 days of pregnancy, Hcg can rise to more than 2500 IU/L. In the first three months of pregnancy, the hcg level is about 2.2 0.5 times higher every day.
