How does pregnancy test sensitivity work?
A pregnancy test has hCG antibodies. Antibodies and antigens are opposite ends of a magnet. As soon as they come in the vicinity, they bind to each other.
Antibodies of hCG can detect urine hCG and thus give a color. They have a pregnancy test dye that shows up only when the pregnancy test detects hCG.
There is a gradation of color in a sensitive pregnancy test. If the test shows faint positive pregnancy test, it means the hCG level is low.
When the hCG levels are high a big fat positive will be displayed. The most sensitive pregnancy test will show very faint positive even when hCG levels are only one mIU/mL extra than the basal level.
A woman with hCG levels around 25 mIU/mL is pregnant for sure. The viability of pregnancy depends on how rapidly these hCG levels pick up.
It is important that you understand that a pregnancy test that detects 6 mIU/mL is more sensitive than the one that detects 25 mIU/mL.
The Superdrug pregnancy test can detect such low levels of hCG.
How does most sensitive pregnancy test work?
Whether be the most sensitive pregnancy test or least they all have the same principle of working. It is simply an antigen-antibody reaction that gives a colored result.
In the case of digital pregnancy test, this result will appear as a phrase or symbol.
When a woman gets pregnant, the fertilized egg travels down the tubes and implants in the uterus. The placenta formation starts after that, and eventually hCG levels rise. It starts from a basal concentration that goes on doubling after every 48-72 hours.
Once the concentration of hCG is enough for sensitive pregnancy test then it can detect it in urine.
What are the criteria for the most sensitive pregnancy test?
The most sensitive pregnancy test is the one that can detect lowest levels of hCG. A pregnancy test for early pregnancy detection is the most sensitive pregnancy test.
The most sensitive pregnancy test can detect traces of hCG present in urine. Unlike a sensitive pregnancy test, others require the hCG levels to rise high for detection by them.

A sensitive pregnancy test also depends upon how well you use it. The sensitivity of pregnancy test dramatically affects by contamination.
When does pregnancy hormone appear?
The pregnancy hormone generally takes a week after implantation to rise to detectable concentration. Before that, there is not enough hCG in blood for detection. Urine hCG levels are lower than those in the serum. In some cases, the woman’s body may take even longer for production of hCG.
After implantation, the protective placenta forms to cover the baby, and it releases hCG. The pregnancy hormone takes over the function for guiding other hormones. The pregnancy hormones take two weeks after conception to appear in bloodstream in enough concentration.
There are some factors that a fertilized egg releases immediately for a shorter span. They are not detectable by the most sensitive pregnancy test.
Only a professional medical examination can detect such low levels of hCG.
