it's not very likely, blood tests are very accurate and HCG (pregnancy hormone) shows in the blood before in the urine. HPT's are not as accurate and sometimes can provide a false positive result, though it's not all that often. Sometimes if you look at the test after the time allowed in the instructions you will see a false positive line. ~pawsalmighty
