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 purple-red band in the test line area (T). A purple-red band appears in the control line area (C) whether or not HCG is present in the specimen. The purple-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 2-8°C for 48 hours before the test; if the storage time needs to be extended, it can be below -20°C. The 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: the urine interface should not exceed the "MAX" line on the note) 2. Test box: Take out the test box from the aluminum film bag, lay it flat on the table, suck the urine with the straw provided in the packaging bag, drop 3 drops of the urine sample into the sample hole, and observe the results for 5 minutes. 3. Test pen: Take the test pen out of the aluminum film bag before use, unplug the cover, let the urine drip on the urine suction port of the test pen when urinating, and maintain the urine collection time for 45 seconds (please pay attention to the urine collection time). Do not get the display window wet), then put on the cover, continue to hold the test pen flat or lay the test pen flat, and observe the results for 5 minutes. result judgment Note: It is invalid after 15 minutes. 1. Negative: only the control line appears, indicating no pregnancy; 2. Positive: The control line and the test line are both colored, indicating that you are pregnant; 3. Invalid: The control line does not develop color, indicating the failure of the test or the failure of the reagent. Please re-test with a new test strip, if the problem persists, stop using this batch number immediately and contact your local supplier or manufacturer Remarks: The color bands of the quality control line and the test line may show shades of color depending on the amount of hCG in the urine. When the concentration of HCG is high, the test line is very obvious, and the control line may become very weak, which is a normal result. Reference 1. Negative - Urine from healthy men and non-pregnant women should not contain HCG concentrations above the sensitivity of the assay. 2. The concentration of HCG varies greatly with the time of pregnancy and among different individuals. Limitations of test methods 1. This reagent is used for qualitative detection of HCG in urine samples, but its concentration cannot be determined. 2. Patients with uterine tumor, molar pregnancy or menopause may have positive results due to high HCG content in urine. If you have multiple tests and the expected results are inconsistent, you must consult your doctor. 3. If the possibility of conception is suspected and the urine test is negative (probably because the urine is too thin or in the early stage of pregnancy), the morning urine can be re-collected after 48 to 72 hours for re-measurement. 4. After the pregnancy is terminated due to natural or unnatural reasons (including natural delivery, cesarean section, habitual abortion or medical abortion), the urine sample will be positive for HCG for several weeks. 5. Other conditions including trophoblastic disease or non-trophoblastic tumor disease (such as endometrial hyperplasia, breast cancer, lung cancer) can also cause elevated hCG concentrations. Therefore, the test results must be judged by doctors after combining other clinical symptoms and other laboratory indicators. Only after the above several possibilities are ruled out, can we use our company's hCG detection reagent to detect hCG in urine to determine whether or not you are pregnant. If you have multiple tests and the expected results are inconsistent, you must consult your doctor. 6. Such as ectopic pregnancy, ovarian cysts can produce negative or irregular results. If still in doubt, a quantitative kit is recommended for testing. 7. Painkillers, oral contraceptives and other common drugs did not interfere with the test results. 8. Under normal circumstances, this reagent is very reliable, but incorrect use may affect the accuracy of the results. For example, the display window is wet or the amount of urine is insufficient. 9. When your test result indicates that you are pregnant, please go to the hospital to see a doctor and confirm the diagnosis, and the doctor will give you further guidance. Product performance index 1. The minimum detection amount: detect with HCG national standard, observe the result in 5 minutes, and not higher than 25mlU/ml. 2. The coincidence rate of negative reference products: 500mlU/ml LH, 1000mlU/ml FSH and 1000mlU/ml TSH are detected as negative. 3. Interference test: urine contains common OTC drugs, chemical analytes vitamin C), biological analytes (such as glucose, protein, bovine serum albumin, bilirubin, heme), etc. affect the test results. 4. Precision: Measured with the same concentration of HCG standard (n=10), the reaction results are consistent with the color rendering. Comment: 1. Manual measurement tolerance is 2-5g. Please don't mind your substitutions. 2. Due to the difference between different monitors, the image may not reflect the actual color of the item. thank you very much! 3.
