Pregnancy tests detect the presence of human chorionic gonadotropin (hCG), a protein that is secreted by the placenta, or newly forming child. These tests can only truly be determined about 6 days after conception.
Can spermicide defect a pregnancy test?
Spermicide should not affect the accuracy of a pregnancy test. Pregnancy tests work by detecting the presence of hCG hormone in urine, which is produced by a developing embryo. Spermicide works by killing sperm to prevent fertilization, and should not interfere with the hormone levels detected by a pregnancy test.
Can a homeade pregnancy test be trusted?

Not at all. In a urine test, being diabetic may show the presence of sugar or ketones, whilst pregnancy tests look for the presence of a hormone in the urine. Being diabetic does not therefore affect the result of pregnancy tests.
Can alcohol be detected in a uranalisis?
Yes, alcohol can be detected in a urinalysis, but traditional urinalysis tests do not typically measure alcohol levels. Specialized tests, such as ethyl glucuronide (EtG) tests, can detect alcohol consumption in urine by measuring specific alcohol metabolites.
Does weed affect a pregnancy test?
