Human Chorionic Gonadotropin Beta HCG is a hormone produced by the mother's organism when a pregnancy occurs. These hormones are only produced in large quantities when a woman is expecting a baby. Both home pregnancy test and laboratory urine pregnancy test analyze i levels of beta-HCG, but after how long can Beta Hcg analyzes be performed?
Le beta hcg they can be done after approx one week after intercourse during which conception took place. For clarity we must say that conception occurs within 24 hours of ovulation but the maternal organism begins to produce Beta hormones only after about seven days.

The betas, then, increase more and more exponentially, doubling every 33-48 hours, and for this reason these hormones, called spy hormones, are analyzed in the first months of pregnancy to evaluate their correct trend.
At the end of the third month, beta Hcg levels settle down and no longer increase for the rest of the pregnancy.
As we said, the home pregnancy test can be done no earlier than one week after intercourse, and therefore conception. However, it is always advisable to wait at least for the cycle delay and then perform the test, to avoid an uncertain or unreliable result. It will be the presence of beta hormones that will define the pregnancy test as positive. On average, the test can be done after 10-12 days from conception and the presence of Beta is a symptom of certain pregnancy.Read also: Beta Hcg how they grow in pregnancy
