Can a blood test determine pregnancy when urine and home said negative?

A pregnancy blood test measures the levels of a hormone called human chorionic gonadotropin (hCG) in the blood, which is produced by the placenta shortly after implantation of a fertilized egg. hCG levels rise rapidly during early pregnancy, making a blood test more sensitive than a urine test for detecting pregnancy. While urine tests can detect pregnancy as early as 10 days after ovulation, blood tests can detect pregnancy as early as 6-8 days after ovulation, which is about two to four days before the expected period of menstruation. Therefore, a blood test is more likely to provide an accurate result earlier on in pregnancy compared to a urine test.

If a urine test or a home pregnancy test result comes back negative, but you are still suspecting pregnancy, a blood test can offer a definitive answer. It's always recommended to consult with a healthcare professional for accurate pregnancy confirmation, especially if you are experiencing symptoms of pregnancy or have any concerns about the results.
