No, alcohol consumption does not directly affect the results of a pregnancy test. Pregnancy tests detect the presence of human chorionic gonadotropin (hCG) in the urine or blood, which is a hormone produced by the placenta after implantation of a fertilized egg. Alcohol does not interfere with the detection of hCG levels, so it will not lead to false positive or false negative results on a pregnancy test.
However, it's important to note that excessive alcohol consumption during pregnancy can have negative effects on the developing fetus and can lead to various health complications, including fetal alcohol spectrum disorders (FASDs). Therefore, it is generally recommended to avoid alcohol consumption while trying to conceive and throughout pregnancy.
