Reliability of home urinary LH tests for timing of insemination: a consumer's study.
In this study, intrauterine insemination (IUI) was timed either after the detection of a urinary luteinizing hormone (LH) surge at home by the patient (group A), or following a positive LH test as interpreted by the gynaecologist (group B). Afterwards, samples tested by the patient were retested by the gynaecologist and vice versa. The gynaecologist also rechecked his own findings and the results were correlated with ultrasound data and charts of basal body temperature. Forty-seven cycles were evaluated. The patient's and the gynaecologist's readings agreed (+/- 12 h) in 42 of the cases (89%), and in five cycles (11%) a difference greater than 24 h was found. The intra-observer variation in the gynaecologist's results was +/- 12 h in four cycles (8.5%). These findings suggest that the LH test can be used as a reliable home device for the prediction of pending ovulation and timing of IUI.
