Blood pregnancy tests used by doctors
Your doctor can give you a blood pregnancy test as early as 11–14 days after ovulation. To perform a blood pregnancy test, the doctor draws blood from a vein in your arm. This blood is sent to a laboratory for testing. The results of most blood pregnancy tests take at least a couple of days. The laboratory then advises the doctor of the result.
Blood test results are about 99 per cent accurate and can detect lower amounts of hCG than urine pregnancy tests. The two main types of blood pregnancy test include:
Quantitative blood test – measures the exact amount of hCG in the blood and can give you an estimate of how far along the pregnancy has progressed.
Qualitative blood test – only checks for the presence of hCG. Since this test doesn’t measure the exact levels of hCG, it can’t offer an estimate of gestation.

I had a urine test that was negative and I wasn't happy with that because I knew I was pregnant, I had a blood test the same day at the doctors and it was positive. A blood test can tell almost straight away!

The very earliest is 7-8 days past ovulation, when the embryo implants and starts producing hCG, but in some cases the embryo has not implanted yet at this stage.
