How to make a pregnancy test at home?

Pregnancy test sticks can be used to test whether the body is pregnant. The test is performed through the human chorionic villus system of human urine. Generally, you need to go to a regular large pharmacy to buy pregnancy test sticks. You cannot make your own pregnancy test stick at home. Even if you make it, the accuracy may not be high. It is safer and more convenient to buy a regular pregnancy test stick. Pay more attention to changes in your body. You can use morning urine to test more accurately.

How to make your own pregnancy test at home?

The method of using the pregnancy test paper is: tear open the aluminum film bag from the notch, take out the test pen and open the cover, let the urine pour on the urine suction port of the test paper when urinating, and maintain the urine collection time for 2 to 3 seconds (please note that when collecting urine, do not exceed the arrow to avoid urine wetting the display window), then put on the cover, continue to hold the test pen flat or place the test pen flat. When you see purple-red liquid flowing on the display window, purple-red liquid will appear in the display window within 0 second to 1 minute, and the result will be judged within 5 minutes.

There are three possible test results: Negative: A purple-red line appears in the test area (control line C), indicating no pregnancy. Positive: Two purple-red lines appear in the test area (control line C and test line T), indicating pregnancy. Invalid: No purple-red line appears in the test area or only one purple-red line (test line T line) appears in the test area, indicating that the test has failed or the test paper is invalid and should be retested.

At present, the production of pregnancy test strips generally requires a strict procedure and can also be made in a laboratory. However, it is still difficult to make a pregnancy test paper at home, and there is no method to provide a homemade pregnancy test paper.

How long does it take for a pregnancy test to show up?

1. Try to use the first urine in the morning for testing, as hormone levels are easiest to detect at this time. Do not drink too much water to increase urine production, as this will dilute hormone levels. Some medications may affect the results of the test, so be sure to read the label instructions carefully.

2. How long does it take to detect pregnancy with a pregnancy test stick? Ovulation occurs around the 14th day of the menstrual cycle. Assuming fertilization is successful at this time, it will take at least 6 or 7 days for the fertilized egg to produce HCG. Pregnancy test sticks determine pregnancy by testing urine HCG. HCG actually starts to be secreted in large quantities after the fertilized egg implants, and the syncytial trophoblast begins to secrete large amounts of HCG. It takes at least 11 days for the fertilized egg to implant. So, the earliest is 6 days. If you want more accuracy, wait until 11 days, as it will be more accurate then. You can make your own guess.

How to read pregnancy test stick

After a woman becomes pregnant, a hormone called human chorionic gonadotropin, or HCG, appears in her body to help maintain pregnancy. The pregnancy test stick can test whether the woman's body contains this substance, so how to read the pregnancy test stick?

1. Control line

Usually the red line above is called the control line. After taking urine, if only the control line appears, it means that you are not pregnant.

2. Testing line

If the test results show two red lines at the same time, both the test line and the control line are red, and the test line is clearly visible, then it means that you are pregnant. If the control line and the test line appear to be one darker and one lighter, it means you may be pregnant. You can test again after two days to confirm whether you are pregnant.

Pregnancy test stick accuracy

Generally speaking, the accuracy rate of pregnancy test sticks from regular brands is about 85% to 95%. Therefore, pregnancy test sticks are not 100% accurate. Not to mention that one dark and one light line on the pregnancy test stick does not mean that you are really pregnant. Even if two lines are detected, sometimes it does not necessarily mean that you are really pregnant. If you want to confirm whether you are really pregnant, you still have to go to the hospital for more accurate examination.

The factors that affect the accuracy of pregnancy test sticks mainly include improper operation, too short a pregnancy period, taking medications that affect the results before the test, expired or damp test products, etc. These will cause inaccurate results of pregnancy test sticks.
