When we are trying to have a baby, we can often be in a hurry or impatience to know if we are pregnant and we tend to take the pregnancy test in advance, so the test can lead to false negatives.

But, When is it advisable to do the pregnancy test?From what date can you give a reliable result? On our site we get rid of any doubts so that you can know if you are pregnant or not.

There are two types of pregnancy test: blood and urine and both measure the level of the hormone hCG which confirms the state of good hope. This hormone is released by the embryo from the moment it implants in the wall of the uterus and increases in level until the end of the first trimester.

The urine test is capable of detecting concentrations of the hormone hCG above 25-50 mUl / ml of hormone, while in the case of the blood test it is capable of detecting concentrations of the pregnancy hormone from 10 mIU / ml. This is why it is easier to detect the hCG hormone in a blood test.

The urine tests are 95-97 percent reliable, and it is advisable to carry out the blood pregnancy test in a medical center to confirm the result.

According to experts, confirmation of pregnancy is offered by the fetal ultrasound performed around the sixth or seventh week of pregnancy, in which it is assessed whether there is embryonic development and a gestational sac.

Through the urine test, the best time to confirm if a woman is pregnant is approximately a few two weeks after ovulation occurs, or about seven days after the first day of delay in menstruation.

If you take a home pregnancy test, which you can buy at any pharmacy, it is best to wait at least one day after the absence, in case you have regular rules. If this is not the case, it is preferable to wait at least a week after the absence.

False negatives in the pregnancy test:

There are some pregnancy tests that claim that they are capable of detecting the presence of the hCG hormone up to 5 days before having to lower menstruation, although experts maintain that if the test is performed in advance it can lead to a negative result despite If you are pregnant, because the hCG levels at the time of the test are still too low to be detected correctly.

False positives in the pregnancy test:

Just as false negative results can occur in pregnancy tests, what are called false positives can also occur, that is, the test confirms a pregnancy that is not actually taking place. This can happen in the following circumstances:

1- If an ectopic pregnancy occurs, that is, the embryo is implanted outside the uterus.

2- Early abortion: the embryo implants in the uterus but its development stops after a few days.

3- Ovarian tumor: the increase in the level of the hormone hCG is one of the markers of this type of tumor.

4- A positive result can be detected due to remains of the medication indicated for fertility treatments.
