You may have read different reports regarding the accuracy of such tests. Most of these tests offer 99% or more accuracy. However, this accuracy may also depend on some factors. For instance, if the home pregnancy test is done on the day on which a woman missed her period then she can expect it to be more accurate. Several reports also suggest that many of the home pregnancy tests make false promises of accuracy to people. Experts have also suggested that a large number of home pregnancy tests are not much sensitive to spot HCG (Human chorionic gonadotropin) in the urine after one or two days of the missed period.
One should also understand that the sensitivity of the home pregnancy test also determines that whether it is accurate or not. Higher the sensitivity of a test, more will be its accuracy. In those cases, where a woman has HCG in her urine due to giving birth to a baby recently, fertility drugs, miscarriage etc. then tests which are not very sensitive are recommended. People should also understand that the accuracy claims which are made by a large number of home pregnancy tests are also meant for promoting the sales. Almost every such test claims that it is the most reliable and accurate test. One should buy a home pregnancy test device from an established and trusted brand.
During pregnancy, high levels of a hormone called human chorionic gonadotropin, or hCG are produced, the presence of which can be detected by home pregnancy tests.
There are three types of home pregnancy tests available. The most commonly used is are test strips or a dipstick, to be either dipped in a sample of urine or held in the urine stream. Another type involves a urine collection cup or well, with a testing device. The third type, more uncommon involves the mixture of a sample of urine with a powder or liquid, in several tubes or cups to produce a chemical reaction. A first morning sample is essential for accurate results. Home pregnancy tests may vary in accuracy because the days of a woman’s menstrual cycle and ovulation can vary from month to month, the exact day of the implantation of the egg may vaary, different home pregnancy test kits have varying sensitivity to hCG.
You can look for home pregnancy kits on the Internet.The best time to use a home pregnancy kit is a few days after you have missed the first menstrual period, although you can use a home pregnancy kit on the first day itself. There are certain guidelines you must follow for any home pregnancy test. Storethe test kits according to the directions. Read the instructions, and understand them thoroughly. Check the date of expiry on the package. Follow the directions exactly. Make sure you are able to observe the color change on the test strip. In case of a timed test, do not try to guess, but use a clock. Keep a record of the result for a later consultation with the health professional.
If you have a kit that requires a first morning sample, you must test the sample within 15 minutes of collection. If a midstream is asked for, urinate a little first, and then hold the dipstick in the stream as you finish urinating. There is no pain or risk associated with these tests, other than the misinterpretation of the results.
Many factors affect the results of a home pregnancy test. The kit may not detect the presence of hCG at a very early stage of pregnancy. Not assessing the result at the proper time as indicated in the instructions. Any residual soap or detergent in the collecting cup may yield a false possible result. Taking of certain medicines or drinking a lot of water before collection of urine may affect the test results too. A false positive may be returned if fertility medicine containing hCG is being taken.
Some Home pregnancy kits are easier to use than others. A blood test can confirm a pregnancy before a blood test can. You may be able to detect the signs of pregnancy by observing your body’s changes. You should consider changes in your nutrition if you are thinking of getting pregnant. You should also find out the time of ovulation as closely as possible.
Pregnancy tests are done by women for knowing whether they are pregnant or not. Human chorionic gonadotropin hormone is detected in the urine by all the home pregnancy test devices.
