Urinary-Based Ovulation and Pregnancy: Point-of-Care Testing
by Samantha F. Eichner and Erin M. Timpe
Our AssessmentThis review article compiles data from articles, textbooks and studies from the past 40 years to provide a comprehensive look at home ovulation prediction and pregnancy tests. Urine luteinizing hormone (LH) tests are found to be more accurate in detecting ovulation when compared to other fertility methods.
