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.

If you are about 20 days late for your period and have pregnancy symptoms but took 2 pregnancy tests and they were both negative what should you do?

Go get a blood test! If you are pregnant is it possible the tests are negative because there is not enough HCG being released into your urine. In this case, it takes longer to detect pregnancy through urine. You need to see your doctor for a pregnancy blood test. Ask for the QUANTITATIVE BETA HCG BLOOD TEST. You'll know without a doubt if you're pregnant or not with this test. I was 9 1/2 weeks pregnant with my first child before they found out I was pregnant. Urine pregnancy tests does not work on me. It was that way with my son, too. But they did a blood test on my at 4 weeks to tell if I was pregnant.

You need to go to your Doctor right away and let them do a pregnancy test through blood work. The pregnancy blood test can pick up your hormone level at a much earlier stage than a home urine test can. If you are in fact pregnant and it is ectopic, the earlier that is determined, the better for your health's sake.
