We activated our profile this last May 2009. Within 3 weeks we had a birth mother. During our adoption process with her, we were contacted by 8 more birth mothers! This website is awesome, we can't say it enough. We have our precious son now and we were able to be at the hospital when he was born! Cole Evan born 8/3/2009! more ...
The accuracy of home pregnancy tests is dependant on several things. In most laboratory studies done on them, they are up to 99% accurate in detecting the hormone hCG in women's urine. But, that doesn't mean that the test that you are going to take will have those same results. Because of human error or a number of other complications these tests can be slightly off.
When it comes to choosing a test, you will want to choose the test that has the lowest level of sensitivity. The tests that can detect the smallest amounts of the hormone are the most sought after because they can work for early detection many times. Some tests are as sensitive as 20 mIU/ml while others are 0 to 10 mIU/ml. In the tests that are at the smaller level, you can begin testing much early than the others. For example, tests that are at 20-25 mIU/ml tests can be used as soon as eight days after you conceive! Remember though that conception can happen up to a few days after actual intercourse.
In most cases, mistakes in these testing results of home pregnancy tests are caused by human error. For example, the misuse of the product can cause the wrong accuracy. Or, you may have drunk a lot of water and therefore diluted the urine sample too much making it hard to detect the levels needed although they may be there. The best urine sample to use is that of the first of the morning.
Also, there are some cases in which the body has begun to prepare for the embryo's creation but the fertilized egg did not become an embryo. It is estimated that nearly half of all fertilized eggs do not make it to becoming embryos at all. Others do and then stop developing. This would give you a false positive on a pregnancy test.
