HCG pregnancy test midstream

Human chorionic gonadotropin (HCG) is a hormone, produced by the developing placenta shortly after the conception and secreted into the urine. Pregnancy Tests are a rapid pregnancy test. It adopts double antibody sandwich method detects the presence of human chorionic gonadotropin (hCG), which appears in urine very early during pregnancy.

 Pregancy tests and specimens should be brought to room temperature(20-30°C) prior to test,  pregnancy tests are designed by sandwich principle for detection of hcg in urine. The test owned characteristics of 25 miu/ml sensitivity, specifity, speedy and simplicity

Characteristic:

1. Early detection of pregnancy as early as 7 days after the fertilized egg implantation
2. Simple to use
3. A variety of design specifications suitable for self-testing use and for professional use
4. Results in 3 to 5 minutes
5. Store in room temperature
6. 24 months shelf life
7. Specimen: urine,serum/urine

 Specimen Collection

Any urine specimen is appropriate for names pregnancy tests, but the first morning urine is optiomal because it generally contains the highest concentration of HCG. Urine specimens may be collected in any clean and dry container which be stored in the refrigerator(4-8°C) for up to 72 hours before assay if it can not be tested immediately. The stored specimens should be allowed to reach room temperature before testing

Procedure

Pregnancy tests and specimens should be brought to room temperature(20-30°C) prior to testing

1. Open the kit,hold the strip at the end without arrow or colored sign
2. Inserted the end with arrow or colored sign of the strip into the urine sample figure 1,waiting for only 3 seconds. Do not immerse the strip into the urine sample over the signed band!
3. Take the strip out and lay the strip flat on a clean, dry and nonabsorbent surface
4. Wait for 1 to 5 minutes and read the results as showed in figure 2

Performance:

1. Sensitivity:25 mIU/ml, 20 mIU/ml, 10 mIU/ml
2. Specificity:No cross-reactivity with 300 mIU/ml hLH, 300 mIU/ml hFSH, and 1000 mIU/L hTSH
