A qualitative hCG test: This test confirms if the blood contains hCG and indicates if you are pregnant or not. Doctors use it to confirm pregnancy 10 days after missing your period or earlier. This partly answers your question how many days after missed period pregnancy test is positive. A quantitative hCG test: This test gives the accurate amount of hCG in a woman's blood including very little amounts.
Doctors can use a blood test to determine pregnancy almost immediately. My friend was 1 week and like 2 or 3 days and it showed in a blood test. With todays technology they could probably tell with blood the day after sex lol. You still need to wait until you missed your period for a doctor to do a blood test. Some at home pregnancy tests can give results up to 5 days before your missed period but they aren't 100% accurate and give alot of false negatives.
