Urine pregnancy test (HCG)

Urine pregnancy tests use laboratory methods to detect levels of human chorionic gonadotropin (HCG) in women's urine. Clinically used for the diagnosis of early pregnancy, can be used to assist in the diagnosis of ectopic pregnancy, estimated threatened abortion and prognosis, and can assist in the diagnosis and follow-up observation of certain malignant tumors and women after conception. Basic Information Specialist classification: maternity check check classification: urine / kidney function test Applicable gender: whether women are fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: 1. Normal person. 2. Complete abortion or stillbirth. 3. After pregnancy, HCG is below 2500U / L, and gradually decline, there is the possibility of miscarriage or stillbirth, when it is reduced to 600U / L, it is inevitable abortion, no need for miscarriage treatment. 4. 4 days after delivery or 13 days after the flow of people. Positive: 1. Urine HCG concentration > 2500 U / L is pregnancy positive. 2. Ectopic pregnancy: The urine pregnancy test has a positive rate of 60%. 3. Incomplete abortion: There is still placental tissue remaining in the uterus, and HCG is qualitatively positive. 4. Some tumors such as hydatidiform mole, choriocarcinoma, male testicular teratoma. 5. Certain endocrine and metabolic diseases: such as pituitary gland, hyperthyroidism, and menopausal syndrome. 6. Some gynecological diseases: such as ovarian cysts, endometrial hyperplasia, etc. 7. After taking chlorpromazine, phenothiazine and other drugs. Tips: Do not drink water and beverages before collecting urine, so as not to dilute the urine; if you can not do the test immediately, you should keep the urine specimen in the refrigerator, but not more than 12 hours. Normal value Normal human urine HCG was negative, <312U / L. (Note the specific reference value depends on each laboratory.) Clinical significance Urine HCG concentration > 2500 U / L is pregnancy positive, seen in: 1. HCG in pregnancy urine can be detected positive 10 days after conception, HCG can reach 2500U/L or more after 35-40 days of conception, and peaks in 60-70 days, reaching 100,000-200,000 U/L. 2. The ectopic pregnancy test has a positive rate of 60%. 3. Incomplete abortion There is still placental tissue remaining in the uterus, and HCG is qualitatively positive. 4. Some tumors such as hydatidiform mole, choriocarcinoma, male testicular teratoma. 5. Certain endocrine and metabolic diseases such as pituitary gland, hyperthyroidism, and menopausal syndrome. 6. Some gynecological diseases such as ovarian cysts, endometrial hyperplasia, etc. 7. After taking chlorpromazine, phenothiazine and other drugs. Urine HCG negative, can be seen in: 1. Normal person. 2. Complete abortion or stillbirth. 3. After pregnancy, HCG is below 2500U / L, and gradually decline, there is the possibility of miscarriage or stillbirth, when it is reduced to 600U / L, it is inevitable abortion, no need for miscarriage treatment. 4. 4 days after delivery or 13 days after the flow of people. Positive results may be diseases: early pregnancy response, ectopic pregnancy considerations Inspection notes: 1. Collect urine that is discharged for the first time in the morning (its HCG concentration is high) and must be collected in a clean container with no other traces; 2, do not drink water and drinks before collecting urine, so as not to dilute the urine; 3. If the test cannot be done immediately, the urine sample should be kept in the refrigerator, but not more than 12 hours. Inspection process Inspection method: Collect the urine discharged for the first time in the morning (its HCG concentration is high), and must be collected and checked by a doctor with a clean, no trace. Take about 10 ml of urine and send it to the designated inspection window of the hospital. Not suitable for the crowd no. Adverse reactions and risks no.
