Ovulation test paper principle

Ovulation test is designed to detect levels of luteinizing hormone (LH) in urine to predict ovulation.

During a woman's menstrual cycle, LH peaks before ovulation. When this peak occurs, ovulation is imminent. Ovulation test contains antibodies that specifically bind to LH. Luteinizing hormone binds to antibodies on the test strip when urine contains sufficient concentrations to produce a specific reaction.

The result is judged by observing the color development on the test strip. If two distinct lines appear, ovulation is usually expected within 2448 hours; If there is only one control line, it means that luteinizing hormone has not peaked or ovulation has occurred.

Whether the method is correct or the test time is appropriate can affect the accuracy of ovulation test results. For example, if the instructions are not followed correctly or the test time is irregular, the results may be inaccurate.

Ovulation test paper can help women understand their ovulation situation, so that the rational planning of sexual life, improve the chances of conception, or for contraception. For women who are difficult to prepare for pregnancy, ovulation test paper monitoring combined with other tests can better guide treatment.
