How early will a blood test for pregnancy work?
Pregnancy tests work by analysing the amount of pregnancy hormone present in your body. Generally, a urine pregnancy test is less accurate for two reasons: a) the hormone is being detected through urine, which can alter moreso than blood, depending on how much water you drink and whether or not you use first morning urine (first morning urine is better for pregnancy tests). b) the pregnancy test itself isn't as detailed and reliable as an analysed blood test. The moment the sperm fertilises the egg, the hormone pregnancy starts circulating in your blood. A blood pregnancy test ought to give clear results within a couple of days. Your GP may want to take more bloods a week or so afterwards to verify the result.
Can a female use male urine to pass a urine pregnancy test?
A urine pregnancy test tests for the "preg hormone" in the urine, which is at a higher level when a woman is pregnant. However, I'm not sure what you're trying to accomplish; a pregnancy test isn't a "Pass/Fail" scenario; it tells you if you're pregnant or not. Male urine on a pregnancy test should test negative.
