From the expiration date to the accuracy of the outcome, these are four things you need to know about the pregnancy test.

All women are given a certain moment of their lives to test a pregnancy test. A seemingly simple instrument that can easily replace the role of a doctor. The pregnancy test is an invention as early as it is too late. It was created for the first time in 1978, a year also known as the period of sexual revolution. But beginnings for his creation date early in time, as early as 1370 before Christ's birth. At the time, females had to urinate for a week over the seeds of barley and wheat. And if there be a new seed born of these seed, then this woman was pregnant.

But what are the things you need to know about pregnancy test?

1. Doctors recommend that the pregnancy test take place early in the morning, more precisely during the first morning urination. As it is known, it measures HCG levels (homan chorionic gonadotrophin), a hormone produced by the female placenta. It is located at higher levels in the first morning urine compared with the next moment of the day, so the test should be done right now.

2. The accuracy of the news does not depend on the price of the test. The only difference is that free tests show the result by means of lines, while the most expensive tests show it by word of mail or denial.

3. The accuracy of the pregnancy test is 97%, leaving a margin of error at 3%. The possibility of error as a result is greater if you are using hormonal or soothing drugs.

4. Like contraceptives, the pregnancy test has an expiration date.Check carefully the date marked in their pre-use amballading. The pregnancy test is recommended to take place a day later after the menstrual cycle is delayed. Women with irregular cycles, on the other hand, must do so 21 days after the last illicit sexual relationship.
