  • No Not always a blood test is more accurate, but not necessarily more sensitive. A lot depends on the lab. A quantitative blood test, usually called a beta hCG test, measures the exact units of hCG in the blood. That means it will detect even the most minimal level. There is another type of blood test sometimes called a qualitative hCG. This is a test that simply gives a yes or no answer to whether you are pregnant. Just like urine tests, labs vary as to what is considered a positive pregnancy test. Common cutoffs for positive are 5, 10, and 25 units. A level under 5 is considered negative. A test that is only triggered at 25 units of hCG is not any more sensitive than several of the urine HPTs.
  • Yes, urine tests test for hCG levels in women and A LOT of women have low hCG levels so the tests come out negative even though they are positive.

Although urine tests are almost 100 percent accurate, there could be something affecting the test that is not a pregnancy. Blood tests, are completely accurate, and i recommend anyone to get a blood test instead of a urine test, because they can tell right away if your pregnant, and it wont be something setting of the pregnancy test, when really it isn't a pregnancy, and it's always important to be absolutely positive. - Nicole.

Yes you should take a blood test. It is more accurate & can be taken sooner than a urine test.

The foam in your urine does not mean you are pregnant. Men's urine will foam also. If you think you are pregnant, A pregnancy test would be more accurate.
