They are all pretty close to 100% accurate when done correctly, that is to say, false positive tests are rare. If by accurate you mean how sensitive the tests are, the tests are very sensitive, in many cases being able to give a result before you have even missed your period. You need to be aware of the limitations of the test, and to read and follow the instructions. If you do not do this, the sensitivity plummets, and you are wasting your money. The tests are done on a first-morning-urine specimen, because that is when the pregnancy hormone (hCG) is most concentrated in your urine.
