Learn How Accurate Are Home Pregnancy Tests

When thinking about getting pregnant, the majority of the women ask how accurate are home pregnancy tests when they use one. The truth is that taking such a test could turn out to be nerve-racking especially if you aren’t certain of the accuracy of the results.

How Accurate Are Home Pregnancy Tests

When should you take a home pregnancy test?

The majority of the manufacturers claim that the tests offer accurate results starting with the first day of a missed period or even sooner. However the results are even more reliable a week after the first missed period. It is a known fact that after a fertilized egg gets attached to the lining of the uterus, the body starts producing hCG.

The thing to know about home pregnancy kits is that during the early stages of pregnancy the hCG levels of the blood increase very fast, in some cases doubling every other day. HCG levels can be accurately detected in urine a week after the first missed period.

However, before the first missed period the kits for home pregnancy aren’t that accurate. If it is important for you to know whether you are pregnant or not right away, you should have a blood pregnancy test. This is more sensitive than the urine test and it can be done at the office of your doctor.

In other cases the home test for pregnancy will show a color change. Some test will spell out the word ‘pregnant’ or ‘not pregnant’ according to the results. It is important to remember that the instructions vary from one test to the other and this is why you should always read the instructions before use.
