How accurate is a blood pregnancy test after 3 weeks of missed period?
A doctor has provided 1 answer
It would be: Close to 100%. Pregnancy tests are very accurate but there can be reasons for false + tests such as: HCG injections, IgA deficiencies, choriocarcinomas, gestational trophoblatic disease or neoplasms ; heterophile antibodies.
