More accurate than a home pregnancy test.

Here is an interesting bit of information for you, it depends on which type of blood test:
"Doctors use two types of blood tests to check for pregnancy. Blood tests can pick up hCG earlier in a pregnancy than urine tests can. Blood tests can tell if you are pregnant about 6 to 8 days after you ovulate (or release an egg from an ovary). A quantitative blood test (or the beta hCG test) measures the exact amount of hCG in your blood. So it can find even tiny amounts of hCG. This makes it very accurate. Qualitative hCG blood tests just check to see if the pregnancy hormone is present or not. So it gives a yes or no answer. The qualitative hCG blood test is about as accurate as a urine test."

The blood test performed to detect pregnancy evaluates the presence of a hormone called human chorionic gonadotropin (hCG).
This hormone is produced by the newly formed placenta associated with a pregnancy. It appears in the blood stream about the time of the implantation of the child into the uterus of its mother. This event (implantation) occurs about three to five days after ovulation and fertillization. hCG is therefore detectable in the blood about 5 to 8 days after ovulation and fertillization. There is therefore about a week during which you are pregnant but may not have detectable levels of hCG in your blood stream--during this time, your blood pregnancy test would be negative. The urine pregnancy test also checks for hCG, but it is not as sensitive as the blood test--this turns positive about the time of one's missed period (about 2 weeks after ovulation and fertillization.). Though it is therefore possible that you could be pregnant in the face of a negative blood pregnancy test, it would be unlikely that your symptoms are caused by an undetected pregnancy. If your pregnancy were far enough along such that your hormone levels (chiefly progesterone) were responsible for your symptoms (fatigue, nausea, vomiting), then a blood test should turn up detectable levels of hCG.
It could not hurt to repeat the blood or urine pregnancy test (the latter should be positive by now if you are pregnant). I would explore other reasons for your symptoms, though. In particular, the reason you needed provera in the first place to induce a period suggests that you may not be ovulating. If this is the case, you would not be producing your own progesterone, and this could make you feel lousy.
Your pink discharge after intercourse could be due to an inflammation of your cervix, which could be caused by an infection or inadequate progesterone. You should have a thorough evaluation by your doctor to get to the bottom of the problem.

It's accurate as hell compared to urine test. Because it has a stronger trace of the hcg hormone or pregnancy hormone in the blood stream... there's no getting around that. if you are pregnant it will definetly be accurate. and an ultrasound can be too but you know you have to go through one hurdle at a time.

It is 99.9%. The blood test can test your hormone levels.

100% completely accurate, unless the doc screws up...

It is the most accurate, most so than a urine test.

You can get a false negative, but not a false positive.
