In the previous post we said that any pregnancy test, either through urine or through a blood sample, try to detect the presence of some specific hormone (CGH). If this hormone is founded, it means that the woman is pregnant.
In that sense, all pregnancy tests are reliable.
If the hormone is detected, the woman is pregnant, and level of reliability of the pregnancy tests in these cases is very high.
This can mean any of the following situations:
1 .- The woman is not pregnant
2 .- The women are pregnant but the pregnancy test, for whatever reason, could not detect the hormone.
3 .- The woman is pregnant, the pregnancy test did not has any failure, but the woman does not even have a high level of hormone in her urine, even when pregnant.
In that sense, all pregnancy tests are reliable.
If the hormone is detected, the woman is pregnant, and level of reliability of the pregnancy tests in these cases is very high.
The only times when it is possible to discuss how reliable are these pregnancy tests, is when a pregnancy test gives a negative result: It does not detect the hormone in the urine of women.
This can mean any of the following situations:
1 .- The woman is not pregnant
2 .- The women are pregnant but the pregnancy test, for whatever reason, could not detect the hormone.
3 .- The woman is pregnant, the pregnancy test did not has any failure, but the woman does not even have a high level of hormone in her urine, even when pregnant.
