A new pilot study conducted by the Institute for Natural Family Planning, College of Nursing of Marquette University, evaluates and compares the beginning, peak, and length of the fertile window as determined by a new luteinizing hormone (LH) fertility tracking app with the Clearblue Fertility Monitor (CBFM). A total of 30 participants were randomized into either quantitative Premom or qualitative Easy@Home (EAH) LH testing system. According to the study of 30 women and 84 recorded menstrual cycles, the Premom LH test strips and EAH LH test strips had high correlation rates with the CBFM (r = 0.99, p < 0.0001) and the LH surge detectable rate was 95% of the cycles by EAH LH test strips and 94% by the CBFM.
