1. Blood tests are definitive when it comes to pregnancy tests. They can detect minimal amounts of HCG in the system, way before an HPT will. Between 7-10 days after conception is the earliest a blood test will confirm pregnancy for you. Blood tests are always 100% accurate. 6% of HPTs come back as false negatives.
2. they can tell about 2 days past implantation and implantation can take up to 8 days past ovulation so it really can vary. . .
3. I've read that the earliest a blood test can determine pregnancy is about 6 days after sex/ovulation. I had one done 2 days before my period at 11dpo and it showed that I was pregnant.
