do pregnancy test reveal the truth?

Answer 1

yes, 99% of the time!

Answer 2

All tests currently available to test for the presence of a pregnancy look for the presence of the beta subunit of hCG or human chorionic gonadotropin in the blood or urine. They are usually performed after a missed menstruation or 2-3 weeks after ovulation.

HCG can be detected in urine or blood after implantation, which occurs six to twelve days after fertilization.[1]. Some home pregnancy tests claim to detect hCG as early as 4 days before the next expected period. Whether that statement is accurate for an individual woman depends on the length of her luteal phase and on how soon that individual embryo implanted. Quantitative blood (serum beta) tests can detect hCG levels as low as 1 mIU/mL, while urine tests have published detection thresholds between 20 and 100 mIU/mL, depending on the brand.[2] Qualitative blood tests generally have a threshold of 25 mIU/mL, and so are less sensitive than some available home pregnancy tests.

This hormone is released by trophoblastic tissue in the placenta. In rare cases, it may be produced by a choriocarcinoma or some other germ cell tumours, or even other forms of cancer, i.e. lung cancer.

so dear i think yes theyreveal the truth

Answer 3

Home pregnancy tests measure the amount of pregnancy hormone in your urine. If you are at the beginning of your pregnancy, you may not have enough of the hormone to be measured by the urine tests you purchase at the store.

But, a blood test is much more accurate. You can get a false negative (if you don't have enough hormone to measure yet), but you Cannot get a false positive (if it says you are pregnant, YOU ARE, or your body would not have that hormone).

Good luck...

sometimes in order for the test to right you must be so long before they will read i was 2 to 3 weeks when i found out i was pregnant with my 2nd child with my 3rd i was around 1 months or so and with my 17 month old daughter i was 3 or 4 months before the test showed possitive

Answer 5

My mom was pregnant three times and the pregnancy tests alwasy read negative. She always had to have a blood test. So they are not always accurate.

Answer 6

They can be an indicator, but there is always a chance they can be wrong. When in doubt, seek a doctor. And ultrasound I think it the best way to tell, but then I've never been pregnant >.<
