Can a Clear Blue Easy test be wrong?

Patient: Hello I recenttly took 2 pregnancy test that were positive but the dr urine test say negative so they had me do blood is this possible?

Doctor: Yes, the urine pregnancy tests are not as accurate as having a blood test performed. Certainly after your results come b ack you will rule out definitely pregnancy.Home urine pregnancy test should always be confirmed with a blood pregnancy test done by your health care provider. I wish you the best.
