Every young and healthy woman will have an ovulation period once a month, during which her body will undergo certain changes, such as lower back pain, chest pain, increased libido, etc. Everyone's situation is different. However, during the preparation for pregnancy, calculating the ovulation period is a necessary task. If you don't want to calculate it yourself, you can also choose ovulation test strips. What does the chromaticity value of ovulation test paper 3 represent?
What does the color value of ovulation test paper 3 indicate
The color value of the ovulation test strip is 3, weakly positive, indicating that the ovulation period has not yet entered. It is recommended to rest and further test to clarify. Ovulation test strips can generally accurately predict ovulation as long as they are used correctly. Generally, one week after the end of menstruation, ovulation test strips are used to test once a day. If a strong positive is gradually increasing on the ovulation test strips, the frequency of testing should be increased, preferably every 4 hours. If the ovulation test strips begin to weaken and rapidly weaken compared to the test strips, it indicates that ovulation is about to occur and sexual intercourse can be arranged. The time range for ovulation is usually within 24-48 hours after the ovulation test strip weakens
The principle of ovulation test strip detection is
1. Ovulation test strips are used for qualitative detection of luteinizing hormone (LH) in human urine, in order to determine ovulation time, and are an in vitro detection and auxiliary diagnosis of female ovulation period. LH is secreted by pituitary cells and its main function is to induce ovulation and corpus luteum formation, maintaining the menstrual cycle in women. The production of LH is controlled by hypothalamic gonadotropin-releasing hormone and also regulated by positive and negative feedback from the ovaries.
2. The peak release of LH is closely related to ovarian ovulation. Healthy women of childbearing age always have small amounts of luteinizing hormone in their blood and urine, but before ovulation, the amount of luteinizing hormone increases by about 2-5 times. Once the LH peak appears, it indicates ovarian ovulation within 24-36 hours. Normal women ovulate every month. After an egg matures in the ovaries, it is released and transported to the fallopian tubes for fertilization.
3. Sperm can survive in the female reproductive tract for 24-72 hours, while the suitable time for fertilization of an egg is only about 24-36 hours after ovulation. Therefore, the fertile period is 2-3 days before ovulation and 1-2 days after ovulation. Ovulation test strips can detect the peak of LH, allowing women to predict the optimal time for conception.
The color value of the ovulation test strip is 3, indicating that the woman has not yet entered the ovulation period. However, if it is preparing for pregnancy, medication should also be taken with caution before entering the ovulation period. If women do not want to have children, they should also prepare for contraception in advance, because not only can they become pregnant by having sex during ovulation, but even if they have sex during the safe period, there is a chance of pregnancy.
