Test for early pregnancy diagnosis, HeberFast Line® Embarazo II is a simple, fast and reliable method.
It is a qualitative immunochromatographic test strip with specific monoclonal antibodies against the hormone human chorionic gonadotropin (hCG) and colloidal gold as a marker, to be immersed in a urine sample, from the first day of amenorrhea.
HeberFast Line® Embarazo II shows the result in just 5 to 10 minutes.
- Kit containing 50 test strips, individually packaged in aluminum bags, together with a desiccant sachet. Each kit also contains instructions for use.
- Kit containing 200 test strips, packed in 40 aluminum bags, each containing 5 test strips, together with a desiccant bag. In addition, each kit contains instructions for use, and a zippered nylon bag to store unused strips after opening the foil bag.
The HeberFast Line® Pregnancy II test can be stored at 2 to 30 ° C in its sealed foil pouch until the expiration date stated on the package. Unused strips immediately after opening the sealed foil pouch should be stored at 2 to 30 ° C in the supplied nylon zipper pouch, together with the desiccant pouch, for a maximum time of 7 days. After that time, the unused strips should be discarded. Do not freeze the bags containing the strips.
HeberFast Line® Pregnancy II is recommended for the detection of the hormone human chorionic gonadotropin (hCG) in urine or serum of pregnant women. This hormone is normally produced by the cells of the placenta of pregnant women, and in normal pregnancies it increases from 5 to 50 IU / L in the first week after the egg is fertilized. On the first day of amenorrhea, it can reach an average of 100 IU / L. Peak levels of the hormone (100,000 to 200,000 IU / L) are reached at the end of the first trimester of pregnancy.
When one end of the test strip is inserted into the urine sample, the latter begins to move inside it, and the hCG reacts with the labeled monoclonal antibody conjugate with colloidal gold, forming an antigen-antibody complex. This immune complex moves into the results window of the test strip and reacts with a second monoclonal antibody (anti-hCG) bound to the solid phase, then forming a first horizontal colored line (positive line). In the absence of hCG in the urine sample, this positive line does not form. At the same time, the excess conjugate, not trapped in the positive line, continues to move, and is captured in an area above it, forming a second horizontal colored line (control line), as a demonstration that the reagents have worked correctly. . The control line is formed with both the samples that contain hCG and those that do not.
