How does the pregnancy test work, and how many days after pregnancy can be understood?

Cirinary Test

It's the most used. It can be purchased at a pharmacy and allows the presence of HCG hormone to be discovered in urine. In fact, antibodies act positively or negatively on its appearance, creating a particular sign. The urinary test is considered reliable, and only in rare cases is positive if there is no pregnancy. It happens that the test turns out negative, but that you're pregnant and it's time because you've removed it very quickly or it's been expired.

The urine test would be done simply by taking a urine sample. In this way almost all domestic tests operate. They're able to appreciate the presence of your pregnancy hormone. It's a hormone produced by embryo implantation in the womb, which happens after about 6-7 days of fertilization.
The function of the test is very simple. It would be sufficient to place a test for a few seconds under the urinary flow or to pour some urine into the special location. The test can be done at any moment of the day, but the ideal would be in the morning, since the hormone is more focused right now.

When can this be a pregnancy test?

You can take a pregnancy test that in the first moment you have a period of delay and suspect that you are pregnant, or even about two weeks (14 days) after having an unprotected sex relationship. However, the test is able to highlight the presence of the pregnancy hormone even if it is in low concentration, so you can do it two or four days before the day of menstruation, but to get a reliable result of a pregnancy test should take place after three or four days from the date on which the period cycle was due. If the answer is negative, it should be repeated again a week later.

Classic and Digital Test

Once you've put urine on the test, you have to wait for a few minutes and then read the result. The classic test will show a red line to show negative results and two red lines to show positive results. The digital test will confirm or deny your pregnancy in written words or face with a meaning, for example, if you are pregnant, a smiling face will appear and otherwise a sad face will appear.

Can we always believe the result of the test under house conditions?

There's a 98-99% maternity test, so you can most often believe it. But for that to happen, you must follow all the guidelines for proper use. In some cases it may be that the test will show a positive false result, so the woman is not pregnant, which can happen as a result of “reference”) that some tests on the hormone beta hCG.

Always in rare cases, but the test may also indicate a false negative result, so the woman is pregnant and the test may show a negative result. This may be because of early testing - when the hormone level has been very low, or if it has been performed with very thin urine - so they have not spent many hours on previous urination.
If you suspect that you're pregnant, the menstruation doesn't come and the test turns negative again, repeat again in a few days or take a urine test.

Blood Test

To understand if you're pregnant you can run two types of blood tests done in the lab.

The quality test is simpler. The quantitative test is much more accurate, and it also reports the exact amount of hCG in the blood, pointing to the date of conception. The credibility of a blood pregnancy test is 100%.

Spitting Test

It's a little popular in Italy, but it's very practical. Calculates the amount of HCG in saliva and is 98% reliable.

When should you take the test?

To obtain a reliable result of a pregnancy test, it must take 10 days after conception or after three or four days from the date on which the period cycle was to come. If the answer is negative, it should be repeated again a week later.
