Pregnancy Test Accuracy

Pregnancy tests are meant to detect the presence of hormone HCG (human chronics gonadotropin) that is a glycoprotein hormone. The developing placenta secrets this hormone after fertilization which is the positive indication of pregnancy. There are two types of test namely Home pregnancy test and clinical test. As the name suggest the latter is done under medical supervision and the former can be done at home with the help of test kits which are easily available in the market. The results of pregnancy test are getting more accurate with the passing time. Both urine and blood test results produce 97%to 99% accuracy. The accuracy of the test depends upon how the test is performed. The best-performed test is bound to give accurate result.

Home Pregnancy Tests
Most of the women go for home pregnancy test. To get the maximum accurate results you need to wait for about a week after the due date of your periods. This will have more concentration of HCG in the urine, which allow for more accurate test. The best time to perform the test is in the morning before having anything because this is the time when there will be upsurge of HCG in the urine. If you are aware of the tests that can be performed on the first day the period is due, then it is better to understand that such tests doesn’t guarantee accuracy and hence cannot be relied upon.

Clinic Tests
The clinical test in the form of blood test can be performed a week before your period is due but still have accuracy of 99%. The best part is it can detect pregnancy before most of the urine tests.
