The first response pregnancy test is used to detect the pregnancy hormone as early as 3 days before the pregnant woman expects her menstrual cycle – that is 4 days earlier than other manufacturers producing pregnancy kits. While taking a First Response pregnancy test (or any other), the user should keep in mind that an average woman has enough hCG in her urine on the very 1st day of a missing menstrual period. In some of the pregnancies, the embryo will take a few days longer to get implanted. A pregnancy test performed that 1st day (or earlier) will come up negative as there is no hCG present that can be traced out. If the first test is negative but the menses do not start within a few days, testing again is advisable as the woman may still be pregnant.
In clinical testing, the First Response pregnancy test has traced the hormone levels in 52 percent of women 3 days before the expected period, in 69 percent of women 2 days before their expected menses, and in 86 percent of women a day before their expected menses. Few of the benefits of First Response pregnancy tests include –
• It can be used as early as 3 days before expected menses!
• It can be tested any time of day.
• It is over 99% accurate in laboratory testing.
• It is 98.4% accurate in consumer studies
First Response home pregnancy tests (HPTs) are designed for detecting hCG, a hormone released by the placenta soon after the embryo has begun to implanting into the uterus linings and the hormone is found in a pregnant woman's urine. hCG stands for human chorionic gonadotropin and home pregnancy tests (HPTs) are designed to trace it. Detecting hCG in the blood and/or urine is how home pregnancy test work.
How accurate are First Response home pregnancy tests is a question. The highest possible screening sensitivities for an hCG-based pregnancy tests conducted on the 1st day of a missed menses is 90 per cent, as 10 percent of women might not have implanted yet inside the walls of the uterus. The experts estimate that the highest possible screening sensitivities of a home pregnancy tests by 1st week after the 1st day of the missed period is about 96 per cent, thus such accuracy is generally not doubted so long as the test directions are correctly followed.
First Response pregnancy test is one of the more sensitive methods that allow pregnant woman to test about 3-5 days before the woman expects her menstrual period. Instructions are in both the language; English and Spanish and include photos. One can conduct the test by urinating on the test wand (or, if preferred, collecting the urine into a cup and then immersing the wand into it for about 5 seconds). After the wand has been dealt with urine as instructed, one should then cover the window with a clear protective overcap and place it flat. The results should be displayed within three minutes and the top of the wand will turn pink indicating the test was done correctly. If the test has successfully worked, the result shows as pink lines in the ‘result window’. One pink line is negative and two pink lines show the pregnancy.
While the First Response Pregnancy Test is very accurate, many things can lead to an inaccurate pregnancy test results and some of them are:
- Medications that have hCG
- Miscalculation of the due date
- Failure to sufficiently saturate the test stick tip
- Over saturation of the test stick tip
- Failure to place the test flat during waiting for the test results for processing
If there is a doubt that pregnancy test result is wrong, waiting three days and retaking the test or visiting with your health care provider is better idea. All in all, First response home pregnancy tests (HPTs) are designed detecting hCG, a hormone that is released by the placenta soon after the conception. It is worldwide accepted and the test is very reliable. Early detection of the pregnancy will help taking early care.
