Pregnancy Tests – How Accurate Are They?

Pregnancy tests work by identifying a hormone known as HCG (Human Chorionic Gonadotropin) in a lady’s blood since the hormones are delivered when an egg is embedded in the uterus. There are two sorts of pregnancy tests, one uses blood and alternative use urine.

A quantitative blood test identifies HCG sooner than a subjective blood or urine test.

Most home pregnancy tests detect HCG in a urine stream.

It requires follow up for a couple of minutes.

A line or image shows up if the trial is sure hence demonstrating pregnancy.

Some home urine pregnancy test involves the second test in a couple of days regardless of what were the primary results.

They tend to be less accurate as compared to the quantitative blood Home pregnancy tests may test positive on the primary day of a missed period, yet all recognize pregnancy one week after a missed period.
