The pregnancy test is a simple device used by women to determine whether there is pregnancy or not. A pregnancy test works by detecting the human chorionic gonadotropin (HCG) hormone in urine or blood.

This hormone is produced from a woman's placenta when a fertilized egg is implanted in the uterus. HCG levels rise after conception and continue to rise until about 10 weeks in pregnancy.

Women who are trying to get pregnant do not need to rush to the doctor every time they miss a period. Home pregnancy test is very simple and easy to perform. The result can be read within few minutes visually. It enables women to seek antenatal care as soon as possible.

Home pregnancy tests can detect the HCG hormone about a week after a missed period and give a 97-99 percent reliability when done correctly.

The following advices can be followed to increase the accuracy of the results for a urine pregnancy test:

1. Perform the test in the morning on your first urination since HCG hormone is more likely to be detected in this period

2. Place the dipstick in your urine stream for 5 to 10 seconds.

3. If the test is negative, you may want to try again in a few days, as you may have done the test too early. HCG gradually increases during pregnancy.

4. The results will be more accurate if you wait until the first day of a missed period.
