Ovulation test paper always shows dark on top and light on bottom

Ovulation test paper, when it comes to this term, literally speaking, it is a pregnancy test paper related to the physiological activities of female friends. Ovulation test strips are common in our daily lives. So, why does the ovulation test paper always show dark at the top and light at the bottom? How to use ovulation test strips? Next, the editor will explain these aspects in detail for everyone.

The ovulation test paper keeps going deep at the top and shallow at the bottom

If the ovulation test paper shows darker colors on the top and lighter colors on the bottom, it means you are not ovulating or the low value has not been reached. Try again the next day. For general ovulation test strips, the upper part is a comparison line. If the lower line is light, it means that LH has not reached its peak value and is still negative. When the lower line is as dark as or darker than the upper line, it indicates that ovulation is approaching. The accuracy of ovulation detection by ovulation test strips is not high, so it is recommended to monitor ovulation by B-ultrasound.

How to use ovulation test strips

1. Generally, the normal physiological cycle is 28 days. The ovulation period is 14 days before the next menarche. Generally, the detection starts on the 11th day of the ovulation period and continues for 6 days. However, not every woman ovulates in the middle or late stages of her menstrual cycle, and a positive result may not appear within the 6-day test period. Some women may ovulate early due to the influence of the natural environment, mood and fatigue.

2. Reduce water intake 2 hours before collecting urine, because diluted urine samples will hinder the detection of LH peak values.

3. The changes in the saturation of the test line during the test period should be observed and recorded. If the test result is negative but the saturation of the test line begins to decrease, it can also be used as the highest LH value.

4. The pregnancy test paper should be observed and reflected within the required time, and it will become invalid after 30 minutes. If there is a negative test result, a faint line may appear at the location of the test line. Check again after a period of time.
