Is a blood test for pregnancy more accurate than a urine test?

In: Medication and Drugs [Edit categories]

Answer:

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.
