How to tell if you are pregnant with a pregnancy test stick

When a woman is pregnant, the hormone HCG in her body will rise. The pregnancy test stick normally uses urine sensitivity to detect whether a woman is pregnant. However, in the early stages of pregnancy, the hormone value in urine is usually relatively low, so the pregnancy test stick sometimes cannot detect it. It is best to detect whether you are pregnant about ten days after having sex. So how can you tell if you are pregnant with a test stick?

How to read the pregnancy test results

1. There are two red lines on the pregnancy test stick: one is located in the test area (T) and the other is in the quality control area (C). It is a positive result, indicating pregnancy.

2. A red line on the pregnancy test stick: Only a purple-red strip appears in the quality control area (C), and no purple-red strip appears in the test area (T). A negative result indicates that you are not pregnant.

3. One line on the pregnancy test stick is dark and the other is light: one line is located in the test area (T) and is relatively light, and the other line is located in the quality control area (C) and is darker. This is a weak positive result, indicating the possibility of pregnancy.

4. There is no red line on the pregnancy test stick: No purple-red strip appears in the quality control area (C), indicating an incorrect operation process or the reagent strip has deteriorated and damaged.

The main principle of the pregnancy test stick is to detect the HCG value, that is, the value of human chorionic gonadotropin. This hormone is produced by the placenta and usually appears in the urine a few days after pregnancy. However, due to the small amount, it is difficult to test it at the beginning and it becomes increasingly obvious after 10 to 14 days. Therefore, it is recommended to test 10-14 days after the menstrual period is delayed. However, even so, the test results of pregnancy test sticks will not be 100% accurate. Therefore, I hope that all women will go to a large hospital for a thorough examination when they feel that they have suspected symptoms of pregnancy, so that they can do a good job of fertility and prepare early.

When to use pregnancy test stick

Using pregnancy test sticks to detect whether they are pregnant is the choice of many women, and the time to use pregnancy test sticks is particular. If the time is not correct, the test results may not be true. So, when should pregnancy test sticks be used?

Pregnancy test sticks are commonly used tools for early detection of pregnancy. The principle is to determine whether pregnancy is achieved by checking the HCG content in urine. HCG is the abbreviation of human chorionic gonadotropin. Five to ten days after successful implantation, the HCG content in human urine will increase. If you use a pregnancy test stick with guaranteed quality and follow the correct method, the accuracy rate of pregnancy testing is over 80%.

1. Because urine begins to produce HCG five to ten days after implantation, and implantation occurs one to two days after female ovulation, it is best to test it one month into pregnancy or 7-10 days after menopause for relative accuracy. Generally, HCG will appear in the urine a few days after the fertilized egg and sperm combine, and it must reach a certain ratio to be detected. It also depends on the method of use. If it is used improperly, there will be errors.

2. Try to use the first urine in the morning for testing, because the hormone level at this time is easiest to detect. If this is not possible, make sure the urine is in the bladder for at least four hours before testing.

3. Do not drink too much water to increase urine, as this will dilute hormone levels.

4. Read the instructions carefully before starting the test and follow each step accurately.

5. Some medications may affect the test results, so be sure to read the label instructions carefully.

6. In addition, if it is an ectopic pregnancy, the HCG level may be very low and therefore cannot be detected by a pregnancy test stick. To confirm the test results, be sure to see a doctor.
