chemical tests for pregnancy look for the presence of the beta subunit of human chorionic gonadotropin (hcg) in the blood or urine. for a qualitative test (yes/no results only), the thresholds for a positive test are generally determined by an hcg cut-off where at least 95% of pregnant women would get a positive result on the day of their first missed period. hcg can be detected in urine or blood after implantation around six to twelve days after fertilization, although some evidence suggests that hcg may be released preimplantation as well. quantitative blood (serum beta) tests can detect hcg levels as low as 1 miu/ml, and typically clinicians will call a positive pregnancy test at 5miu/ml. urine test strips have published detection thresholds of 10 miu/ml to 100 miu/ml, depending on the brand. most home pregnancy tests are based on lateral-flow technology.
