Professional and lay interrater reliability of urinary luteinizing hormone surges measured by OvuQuick test
Objective:
To determine the reliability of women, unmotivated by fertility problems, to accurately assess and record the urinary luteinizing hormone surge indicated by color changes on OvuQuick test pads.
Design:
A descriptive, correlational study testing the reliability and validity of an instrument.
Setting:
The participants' homes.
Participants:
114 college-educated, white women.
Interventions:
An OvuQuick Test Kit and a Menstrual Cycle Diary were mailed to each participant. The monthly diary and test pads of the participants were reassessed by a master's-prepared nurse.
Main Outcome Measures:
Women without medical or health-care training are reliable in judging the color changes on the OvuQuick test pads and recording these results in a menstrual diary.
Results:
Investigator and subject assessment and recording of luteinizing hormone surge results agreed 95% (284 of 300 instances) of the time. In addition, the validity of the luteinizing hormone surge for predicting ovulation was accurate in 93% (26 of 28 instances) of the cases.
Conclusion:
OvuQuick is a reliable and valid test for home evaluation of luteinizing hormone surge and prediction of ovulation.
