HCG semi-quantitative

The HCG red blood cell sedimentation inhibition semi-quantitative test (hereinafter referred to as HCG semi-quantitative) has high sensitivity, so it can diagnose early pregnancy, threatened abortion and external pregnancy, and can diagnose, evaluate and follow up the trophoblastic disease. This method requires simple, rapid and economical equipment. The primary hospitals can carry out radioimmunoassay. Although the enzyme labeling method is more sensitive than this method, there is no certain standard for the diagnosis of trophoblastic diseases. Basic Information Specialist classification: maternity check check classification: blood test Applicable gender: whether women are fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: Not pregnant. Positive: pregnancy. Tips: Blood HCG early pregnancy test can often be detected after one or two days of menopause, confirm the time of pregnancy, so that you can take appropriate countermeasures for pregnancy. Normal value Negative performance. In the first 3 months of pregnancy, HCG levels are approximately doubled every (2.2 ± 0.5) days, urine HCG (HCG semi-quantitative method) non-pregnant women <25IU / L, pregnancy 40 days > 5000IU / L, pregnancy 60 ~ 70 Day>(8~32)×104IU/L (the highest level of urine HCG in the morning, close to serum level). Clinical significance Abnormal results: HCG examination is of great significance for the diagnosis of early pregnancy, and has certain value for the diagnosis, identification and disease course observation of diseases related to pregnancy, trophoblastic tumors and the like. 1 ectopic pregnancy, such as ectopic pregnancy, this test only 60% positive rate, after 3 days of uterine bleeding, HCG can still be positive, so HCG examination can be used as its identification with other acute abdomen. HCG is often 312 to 625 IU/L. 2 abortion diagnosis and treatment of incomplete abortion, such as the presence of placental tissue in the uterus, HCG test can still be positive; HCG from positive to negative or negative still negative, so it can be used as a reference for the treatment of abortion or inhalation. 3 trillion first abortion, such as urine HCG still maintain high levels and will not occur inevitable abortion. If the HCG is below 2500 IU/L and gradually declines, there is a possibility of miscarriage or stillbirth. When it is reduced to 600 IU/L, it is inevitable to abort. In the treatment of miscarriage, such as HCG continues to decline, indicating that the miscarriage is invalid, such as HCG continues to rise, indicating that the fetus is successful. 4 Endocrine diseases such as pituitary disease, hyperthyroidism, gynecological diseases such as ovarian cysts, uterine cancer and other HCG can also be increased. In recent years, it has been found that HCG can also be elevated in blood of malignant tumors such as teratoma, pancreatic cancer, stomach cancer, liver cancer, breast cancer, lung cancer, etc., so HCG is regarded as one of cancer markers. However, it is necessary to combine the clinical situation and other test results to comprehensively analyze and judge the results. People who need to be examined: pregnant women who are pregnant generally require an examination. Some cancers and endocrine diseases can also be examined. Precautions Contraindications before inspection: You can not check on an empty stomach. Requirements for examination: Blood HCG early pregnancy test can often be detected after one or two days of menopause, confirming that the time of pregnancy is advanced, so that the corresponding countermeasures for pregnancy can be made earlier. Urine HCG testing such as early pregnancy test strips is usually not detected after one week of menopause. Inspection process Urine testing was carried out in the usual manner. Qualitative test of serum When the patient's urine test is weakly positive or negative and has clinical indications, take 1ml of venous blood, place it for 30min, centrifuge at 3500rpm for 10min to separate the serum, put the early pregnancy test strip in the serum, and observe the result within 5min. , reporting methods are the same as urine testing. Not suitable for the crowd There are no special taboos. Adverse reactions and risks There are no related complications and hazards.
