First response pregnancy test is designed to detect HCG, which stands for human chorionic gonadotropin. It is a hormone released by the placenta in a pregnant woman’s urine right after the embryo begins implanting into the uterine lining.
As soon as the first response pregnancy test came into being, it aroused great applause from both pregnant women and professional doctors. You may wonder in what way the first response pregnancy test is superior to other pregnancy test. The greatest advantage of the First Response test is its nature of sensitivity. The first response pregnancy test can detect the pregnancy hormone, HCG as early as 4 days before the expected period of most pregnant women. If you expect your period on the 22nd day of the month, you can test as early as the 18th day of the month. Also, you can use the first response pregnancy test at any time of the day. In addition, you do not have to use the first morning urine, even though it is recommended to use by doctors because the first morning urine contains the highest level of the pregnancy hormone.
Many women decide to chose to use the first response pregnancy test is also for its accuracy. The highest possible accuracy is over 90 percent for an HCG-based first response pregnancy test conducted on the first day of a missed period. The inaccuracy happens when some of the subjects may not have implanted yet in the uterus and others may not have detectable amounts of hormone in their urine on the first day of the missed period or may have miscalculated the first day of their period. In a recent study of urine samples of both pregnant and non-pregnant subjects, laboratory technicians obtained the correct expected results in more than 99% of the samples who have done the first response pregnancy test.
If only you follow the instructions enclosed in the pack before carrying out, the first response pregnancy test is really simple to conduct. However, if used incorrectly, the tests will not be accurate as expected, so it is essential to read the entire set of instructions before beginning to test. If you have read the entire instructions, you can do the test step by step. The first response pregnancy test can be conducted at home by using your urine. You should urinate a little first and then either hold the test stick directly in your urine stream or collect some with a collection cup.
