In 1963, a small study released this test and found that it predicts pregnancy with 70% decent accuracy, even though it could not accurately tell the sex of the baby. Scientists think the test works because the urine of pregnant women contains a lot of estrogen, which can promote sperm growth. It is now easier to take this ancient method for granted because modern pregnancy tests give accurate results in minutes.
How do they work?
The unanswered pregnancy test is all designed to find one thing: a hormone called HCG.
HCG is produced in the early stages of pregnancy and begins a cell phone game that tells the body not to empty the lining of the uterus during that month. As pregnancy progresses, HCG supports the formation of the placenta, which carries nutrients from the mother to the fetus. The test begins when urine is applied at the end of the line. As this fluid rises up through the suction tubes, it will break through three separate parts, each with an important function. When the wave hits the starting point, the reaction area, Y-shaped proteins are called antibodieswill that bind any HCG. Attached to these antibodiesis is a portable enzyme with the ability to open up dye molecules, which will later become important on the road. The urine then takes all the AB1 enzymes and carries them to the test site, where the results appear. Protected in this area there are additional Y antibodies that will also attach to the HCG on one of its five binding sites. Scientists call this type of testa sandwich assay. When HCG is present, it acquires a sandwich between the enzymes AB1 and AB2, and attaches it to the test site, allowing the activated dye activatingenzyme to perform its function and form a visible pattern. In the absence of HCG, urine and enzymes pass by. Finally, there is one last point to be made, the control area. As with any good test, this step ensures that the test works properly. Even if the AB1 enzymes have never been exposed to HCG, or more because Zone 1is is so full of it, all the non-binding AB1 enzymes taken from Zone 1 should end here and activate more dye. So if a pattern does not appear, that indicates that the test was incorrect.
These tests are very reliable, but they do not fail. For example, illicit substances can occur if the HCG concentration is not high enough to detect. After ingestion, HCG levels double in two to three days, so it may be too early to tell and beverages can reduce the amount of urine sample, which is why doctors recommend taking the first thing to check in the morning.
On the other hand, false positives come from other HCG sources, such as IVF injections, ectopic pregnancy, or other cancers such as cervical cancer or testicular cancer making it easier for one of these test subjects to tell a man that she is pregnant. The best way for a woman to get it is certainly at the doctor's office. Doctors are looking for HCG, but with more serious and quantitative tests, which means they can find the exact amount of HCG in your blood. A few minutes may feel forever while you wait for the results of a pregnancy test. But in that short time, he testifies to the power of the scientific method. That one small stick allows you to ask a question, do a controlled test, and analyze the results of testing your first impression and the good part is that you won't have to wait until the next harvest.
Conclusion: HCG(Human chorionic gonadotropin) hormone detection is very important, by the time we can understand that she is pregnant or not but still if we can detect it early then we can overcome somany complection regarding pregnancy. Emotional side also involves in it and medical procedures like taking medicines which will be helpful for till the birth of child.
