Generally, many women use pregnancy testing sticks and other methods to check if they are pregnant in the early stages, usually for at least 10 days after sexual intercourse. When using pregnancy testing sticks, attention should be paid to the method and approach, otherwise errors may occur, leading to inaccuracy. In principle, it is accurate. Below, we will explain the health knowledge about pregnancy testing sticks.
1、 Will the pregnancy test stick be inaccurate
The pregnancy test stick is accurate. First, ask yourself if you have had sexual activity before, then check if the pregnancy test stick has expired and if it has been used correctly. Then, test again every few days and finally go to the hospital for examination. Generally speaking, the accuracy rate of a legitimate brand pregnancy test stick purchased from a regular pharmacy is about 85% to 95%. Before conducting a pregnancy test, it is important to clarify some issues. Ovulation occurs around the 14th day of the menstrual cycle, and if fertilization is successful, it takes at least 6-7 days for the fertilized egg to produce HCG. The pregnancy test stick is determined by measuring urine HCG, and implantation of the fertilized egg takes at least 11 days.
2、 How to use a pregnancy test stick
1. Firstly, when using, tear open the packaging along the gap and remove the pregnancy test rod. Wear the disposable plastic film gloves included in the box, hold one end of the pregnancy test rod handle tightly with your thumb, tilt the urine suction hole downwards, and make sure that the observation side of the pregnancy test rod is facing downwards, with the direction of the plum blossom pattern facing upwards. Then align the suction hole on the side of the pregnancy test rod to urinate, allowing the urine to pass through the suction hole and maintain a urine collection time of 1 to 2 seconds. Finally, flip the pregnancy test stick with the observation window facing upwards, continue to hold the pregnancy test stick diagonally, and wait for the results.
2. The fertilized egg only secretes HCG after 7 days of development, so it should not be tested on the second day of sexual intercourse. Due to the fact that women usually ovulate between two menstrual periods, such as on the 28th day of the menstrual cycle, ovulation may occur around the 14th day. In addition, implantation takes about 7 days, and an increase in HCG secretion takes some time. Therefore, it is generally recommended to have a pregnancy test after the next menstrual period, as the accuracy will be higher.
3. It is best to use morning urine for pregnancy testing. The morning urine usually has the highest HCG value, and the results are more accurate. If self testing is done at night, the accuracy will also be affected to some extent. Moreover, the HCG content in the early stages of pregnancy is not high, which may lead to undetectable or "one deep and one shallow" conditions.
The above are some questions about pregnancy test strips. In fact, there are many methods to detect pregnancy, the most accurate of which is to go to the hospital to draw blood and HCG, and some are to test morning urine, usually after 10 days. The later, the more accurate. Early pregnancy test strips are also possible, but the method must be correct. Sometimes, incorrect methods may lead to incorrect results.
