With the development of technology, medical technology has also made continuous progress. Many families can also afford some common medical tools, such as pregnancy tests, early pregnancy tests, etc. If women want to know if they are pregnant and are currently very busy, they can first go to a pharmacy to buy pregnancy test strips or pregnancy sticks for testing, and then go to a regular hospital for confirmation. So, what does' early pregnancy on the tenth day of sexual intercourse 'mean by' whiteboard '?
Early pregnancy whiteboard on the tenth day of sexual intercourse
In theory, on the 9th day of ovulation, which is the 23rd day of menstruation, pregnancy can be detected using more sensitive methods. When using early pregnancy test strips, if the whiteboard is detected, it means that the patient is not pregnant at this time. Of course, it is also possible that the test was taken too early, so it cannot be detected yet. Generally, eggs can survive in the fallopian tubes for 1-2 days after being released from the ovaries, waiting for fertilization; Male sperm can maintain fertilization ability in the female reproductive tract for 2-3 days, and after the egg and sperm combine, they do not immediately become embryos, but take some time to be detected. Therefore, for safety reasons, it is usually more accurate to use early pregnancy toilets 14 days after sexual intercourse during ovulation.
The correct usage method for early pregnancy
Generally speaking, the most accurate result can be obtained by using the urine excreted for the first time in the morning. Because early morning urine generally has the highest HCG value. If pregnancy self testing is done at night, the accuracy will also be more or less affected.
The correct use of early pregnancy test strips:
1. Before conducting the test, it is necessary to read the user manual completely and restore the reagents and urine samples to room temperature (20 ℃ -30 ℃) before use.
2. Remove the reagent strip from the original aluminum foil bag and use it as soon as possible within 1 hour.
3. Insert the reagent strip into the urine sample in the direction of the arrow Attention: The urine level should not exceed the marking line of the reagent strip.
4. After at least 5 seconds, take it out and place it flat on a clean and flat surface to observe the results.
5. Wait for the appearance of the purple red band. The test results should be read within 3 minutes and judged invalid after 10 minutes.
Although early pregnancy test strips claim to have an accuracy rate of 99%, the actual correct testing rate of early pregnancy test strips varies greatly, ranging from 50% to 75%.
Many women tend to choose methods such as pregnancy tests and early pregnancy tests when determining whether they are pregnant. These methods are convenient, but at the same time, testing tools such as pregnancy tests and early pregnancy tests cannot guarantee 100% accuracy. Therefore, after using pregnancy tests and early pregnancy tests for initial testing, in order to ensure accuracy, it is still necessary to go to the hospital for further confirmation.
