principle
Human chorionic gonadotropin (HCG) is a glycoprotein hormone produced by the placenta during pregnancy. HCG can be detected in the urine of pregnant women after conception. HCG can increase to 5 to 50 milliinternational units per milliliter (mIU/ml) about a week after conception, peaking at 100,000 to 200,000 milliinternational units (mIU/ml) at 10 weeks, and then rapidly declines after 12 weeks , maintained at 5,000-20,000 milliinternational units/ml (mIU/ml). The appearance of HCG changes in the post-pregnancy period as the embryo grows, and this phenomenon is the best marker for early detection of pregnancy.
The early pregnancy test strip is based on the principle of one-step method of colloidal gold-labeled immunochromatography, which can quickly, accurately and simply detect the content and changes of HCG in the urine of women of childbearing age, and is used to determine early pregnancy in women (3-7 days after pregnancy). ), so as to achieve the purpose of excellent pregnancy or early drug termination of pregnancy.

Inspection principle
This strain is made by sticking human chorionic gonadotropin (HCG) antibody and anti-mouse IgG respectively on solid-phase nitrocellulose membrane, colloidal gold-labeled anti-HCG monoclonal antibody and other reagents in turn. Immunochromatographic double-antibody sandwich method is applied. principle.
During the test, the urine sample is dripped onto the test strip and chromatographed upwards under the capillary effect. If it is positive, the HCG in the sample first binds to the colloidal gold HCG antibody during the chromatography process, and then continues to be chromatographed upward, and then the conjugate will be bound by the HCG antibody immobilized on the membrane, which will appear in the test area (T). A fuchsia strip. This band is formed by the complex of HCG antibody gold-labeled particles combined with HCG antibody on the membrane. If negative, there will be no red band in the test line area (T).
A red band appears in the control line area (C) whether or not HCG is present in the specimen. The red band displayed in the control line area (C) is the standard for judging whether there is enough sample and whether the chromatography process is normal, and also serves as the internal control standard for the reagent.

Sample requirements
Urine specimens can be collected in a clean, dry container. Urine can be detected throughout the day, but HCG concentrations are usually highest in morning urine. If the specimen is not tested immediately, it can be stored at 2-8C for 48 hours before the test; if the storage time needs to be extended, it can be frozen below -20C. The frozen specimen should be fully melted and returned to room temperature before testing, and shake well. When the urine sample is cloudy and precipitated, do not shake it, take the supernatant for testing; or take the supernatant by centrifugation or filtration for testing.
How to operate
The tested samples, reagents and other equipment should be returned to room temperature before use. If the package is opened, it should be used as soon as possible within 1 hour.
1. Test strip: Take out the test strip and immerse the end marked with the arrow mark in the container with urine vertically. After at least 3 seconds, take it out and lay it flat on a clean non-absorbent material plane and wait for the appearance of the colored strip. 5 minutes to observe the results. (Note:
