Are blood or urine pregnancy tests more accurate?
Blood tests are more accurate, but this depends on the type of blood test used. Beta hCG blood tests can measure the exact amount of hCG present in blood and can detect the smallest amounts, whereas qualitative hCG blood tests can only give a yes/no answer regarding pregnancy and require a minimum of 25 units of hCG in the blood to return a result, making it no more accurate than a home pregnancy test.
