Home pregnancy tests are fairly accurate but cannot be relied on a hundred percent of the time. Any home pregnancy test that is available commercially basically detects the presence of subunit of human chorionic gonadotropin or HCG in the urine or blood of the woman. Certain home pregnancy tests claim to detect the human chorionic gonadotropin about four days before her next menstrual period. Home pregnancy tests are a quick and rather unobtrusive way of determining whether or not a woman is pregnant.
The earliest test that can be conducted for ascertaining a pregnancy is the rosette inhibition assay for EPF or early pregnancy factor, which incidentally can be detected in the bloodstream around forty eighty hours after fertilization has taken place. However it must be noted that not only is EPF a lengthy and time consuming procedure but it is also an expensive one.
