About 8 days after: Blood HCG tests detect levels very soon after embryo implantation starts. The embryo usually start implanting at about 7 days after conception.

Yes, sort of: A blood or urine pregnancy test detects HCG hormone, not pregnancy per se. If a person has a tumor producing HCG the test will be positive but wrong in that the person is not pregnant. If you do the test too early and it is negative, it could be construed to be wrong as the women is pregnant but the fetus has not yet made enough hcg. ...Read more

1day: At the lab it takes < 24 hours - however it may take longer to get to you. I'd call next day and ask them to "call and get result" if it's not available. Typically, most offices say " 2-3 days" before results are back..... But..... Good luck! ...Read more
Dunno: The most accurate test is for the beta chain of human chorionic gonadotropin. It is a quantitative test (gives you a number, not a decimal) and is detectable as early as 5 days after implantation of the fertilized egg into the uterine wall. I don't know what test you had but you can get a quantitative beta HCG. ...Read more
Yes and no:
Usually if a woman is 16 days late she is at 4 weeks gestational age and the blood pregnancy test would have to be positive.
But if that women had just randomly a late ovulation, say she ovulated 3 weeks later than normal, a woman could be just a few days pregnant and the blood test would be negative. But she would still be "late". ...Read more
Had a blood pregnancy test at four weeks and it was negative. How accurate is this at four weeks?
Is it possible to get the results of a blood pregnancy test in less that 20 min. Or does it take longer to process?
Depends where: Doing the test itself is fast but unless your doctor is processing blood work in the office it probably is being referred out to an outside lab company. Doing a urine test is much faster and can detect pregnancy with a BHCG of > 20. This means it only misses pregnancy in the first few days after conception ...Read more

Yes: Beta HCG is measured in both blood and urine and is usually detected between 6-12 days after fertilization when implantation occurs. A quantitative bhcg can measure very low levels of bhcg but the typical qualitative blood test usually turns positive at a higher level and is not always better than the urine test. So to be sure you might want to retest some days later. ...Read more
