Ovulation test strips are a little helper for couples preparing for pregnancy, which can effectively detect the ovulation period. But many female friends encounter problems when using ovulation test strips, which affects everyone's normal judgment. It is very common for ovulation test papers to be one deep and one shallow. So what is going on? Let's take a look together.
The principle of ovulation test paper
Due to the peak secretion of luteinizing hormone (LH) in the body during ovulation, ovulation test strips are used to detect women's ovulation period based on this principle. Generally speaking, 1 to 2 days before the upcoming ovulation period, the secretion of LH luteinizing hormone changes from weak to strong, and the ovulation test paper shows a weak positive gradually becoming a strong positive. When the ovulation period truly arrives, the luteinizing hormone in the body will decrease, and the ovulation test strip will change from strong positive to weak positive. Therefore, the principle of ovulation test strips lies in this.
What is the reason for the depth and shallowness of ovulation test paper
One is the appearance of two red bands, with the detection line being noticeably lighter than the control line, indicating that LH in urine has not yet reached its peak and must be tested daily. This result is negative. Another type is the appearance of two colored bands with the detection line darker than the control line. Indicates the presence of LH peak, indicating ovulation will occur within 24-48 hours. This result is a positive result. Therefore, if the ovulation test paper appears to be either deep or shallow, it depends on which day is the detection line and which is the control line, in order to determine the result.
The above is the relevant content about the depth and shallowness of ovulation test paper introduced in the encyclopedia. I would like to remind everyone to carefully read the instructions and follow each step accurately before starting the testing; Do not take medications such as hormones that may affect the test results. When you avoid these situations, the pregnancy test will be accurate.
