How to take the pharmacy pregnancy test

As mentioned before, to take the pharmacy pregnancy test, just follow the package procedure. However, it is important to know the utensils made available by the brand, in order to ensure greater accuracy, also avoiding contamination.

This is because some brands provide the container to store the urine during the investigation, while others indicate that it should be done directly on the tape. Therefore, it is worth checking how the chosen one works, to follow the step-by-step correctly.

However, in general, pregnancy tests should be done 2-5 after missed period. And preferably with the first urine of the day, which according to specialists, carries a higher concentration of the hormone beta-HCG, related to pregnancy.

How to take the pregnancy test – step by step:

Afterwards, the procedure should be as follows:

  • Wash your hands and keep them sanitized to start with the test;
  • If the test is with a strip, the urine must be done in a small container that comes with the product or a clean, disposable plastic cup. However, there are options to urinate directly on the tape, such as digital tests;
  • In the case of the tape test, after peeing in the pot, it is necessary to place the tape up to where there is an indicative mark, however, if it is with the urine directly on the tape, it is necessary to close it with the lid that comes with the product; and
  • Wait for 5 to 10 minutes;
  • After the stipulated time, in the case of the test with the tapes, the result will come out with red or pink stripes and in the electronic model, it will be informed with “not pregnant” or “pregnant”.

Therefore, the test on the tape models will be presented as follows:

Therefore, when identifying two bands, the result is positive and she is expecting a baby, however if there is only one, the woman is not pregnant.

In addition, there may still be some doubtful situations, where light bands appear when presenting the result. If this happens, it is worth repeating the test or even preferring the blood test, which will reveal more accurately the pregnancy and the period in case of positive.

pregnancy test with blood test

The pregnancy test made from the blood test is the most reliable, as it will measure the level of beta-HCG hormone in the body, resulting in truthful information with high reliability. In addition to informing the average time of pregnancy.

This is because, for more certainty, an ultrasound is needed, which will provide the size of the fetus, where the doctor will be able to certify the period of pregnancy according to this information.

However, the blood test is essential, as it has a 99% success rate . In addition to being extremely necessary for the progress of prenatal care.

To do this exam, a medical request is necessary, which can be obtained both in private hospitals and in the SUS. Normally, the exam is done at any time of the day and the result comes out in an average of 24 hours, providing an accurate picture of the woman’s current condition.

Therefore, even with the pregnancy test, do not waive the blood test and in case of a positive result, immediately start monitoring with the obstetrician, in order to ensure the health and well-being of the mother and baby throughout the pregnancy and until later.

How Pregnancy Test Works: Beta HCG Quantitative

As mentioned before, beta-HCG and or BHGC is a test capable of quantifying the hormone that is usually elevated in cases of pregnancy.

To measure its quantity it is necessary to carry out a blood test, as already informed. And, in addition to pointing out the existence of pregnancy, it will indicate the period of pregnancy. Essential information for correct control and care.

It can be done 10 days after fertilization or after the first day of missed period . And it reports the result with 99% accuracy.

To identify, a quantitative parameter is followed, as follows:

  • BhCG below 5 mIU/ml:  negative result, ie there is no evidence of pregnancy;
  • BhCG between 5 and 25 mIU/ml : undefined result. Therefore, it is recommended to repeat the exam after three days to be sure about the pregnancy; and
  • BhCG above 25 mIU/ml:  positive result, indicating pregnancy.

So, if you took the test, you have the result, you have not had a medical appointment yet and you want to know if you are pregnant, check if the BHDCG is above 25 mIU/ml. If so, congratulations, as there are great chances of being pregnant.

And in addition to this exam, in some situations, obstetricians can also ask for ultrasound or fetal sexing to find out how the fetus is doing. Therefore, do not give up the medical consultation and start prenatal care as soon as possible to ensure balance and health throughout the pregnancy.
