Do pregnancy tests always detect if you are pregnant?

Answer 1

I took the Clear Blue. It's about 20 dollars at your Randall's store and you get two in the box so it's worth it. I took it the day of my expected period and it came up positive. A week later I took the other test just to make sure and it was positive too. There are some other brands that can detect it earlier but it just made more sense to me to wait until I had enough of the hormone to detect it the first test that way I didn't waste my money on multiple test. Good luck I hope you get the outcome you were are looking for.

Answer 2

According to the ClearBlue pregnancy test accuracy results they are: 4 days before expected period= 51% accurate

3 days before expected period= 82% accurate

2 days before expected period= 90% accurate

1 day before expected period =95% accurate

the day of expected period =99% accurate

There are several things that can contribute to a negative pregnancy test even if you are pregnant. Some medications can give you a false negative, the timing of the test can affect the results. If you did not follow directions properly; if you let the test sit for too long the results may read negative after a while. It is important to read the results within the amount of time given on the instructions of that particular pregnancy test you bought. If you did not perform the test properly (example: you drank a lot of fluids before taking the test, which can dilute your urine). Etc To ensure the best results: * Take the test in the morning, if possible, because your hCG (pregnancy hormone) levels are at it's highest * Don't drink a bunch of fluids before taking the test because it will dilute your urine and can affect the results * Take the test no more than 1 day before expected period. Although some test say that you can see results up to 5 days before your missed period, the percentage of accuracy is very low. * urinate for as long as possible on the foam-like strip * Check the results in the window frame of time suggested by the instructions of the pregnancy test. . On rare occasions you can encounter a false positive due to improper testing, expired pregnancy tests, rare medical conditions such as certain types of cancer, evaporation lines, a recent pregnancy or a chemical pregnancy.

Answer 3

If it's JUST a pregnancy test, the only thing it's looking for is HCG--the hormone your body gives off when it's pregnant.

'Course, if I was a doctor running pregnancy tests I would also test for drugs. But that's two separate tests--one for drugs, one for pregnancy.

Answer 4

A pregnancy test tests for a hormone called HCG (Human chorionic gonadotropins) produced in pregnancy that is made by the developing embryo after conception. Its role is to prevent the disintegration of the corpus luteum of the ovary and thereby maintain progesterone production that is critical for a pregnancy in humans.

Answer 5

nope..sometimes the pregnancy test can't detect...but if you wait until your missed period, they are more accurate. A blood test done at the doctors are very accurate.

Answer 6

Levels of human chorionic gonadotrophin (hCG) which only pregnant women have elevated levels of .
