This pregnancy test is an accurate quantitative pregnancy blood test (beta-hCG).
Why do this test?
A blood pregnancy test is much more accurate than a urine test. It becomes positive 7-12 days after falling pregnant (conception) and is 99% reliable. A number of 5.8 or more is positive for pregnancy and gets higher during the course of the pregnancy reaching a maximum around 9-12 weeks before getting less for the rest of the pregnancy (see below). For this reason you can also use a pregnancy blood test to see how a pregnancy is progressing. It is therefore sometimes used to check for miscarriages.
A urine pregnancy test, on the other hand, is usually done when you have missed a period and is 97% accurate. That is why women sometimes do more than one test just to make sure. It usually becomes positive 2 weeks after getting pregnant (conception).
Results take 1 working day * and will be e-mailed to you with a doctor's explanation.
* Indicative timings only. Actual result may be earlier or slightly later.
Beta-hCG Levels and Pregnancy:
Levels of beta-hCG less than 5.8 indicate a negative pregnancy test.
Levels of beta-hCG more than 5.8 indicate a positive pregnancy test.
