A RAPID LUTEINIZING HORMONE RADIOIMMUNOASSAY FOR THE PREDICTION OF OVULATION

Abstract

Summary A rapid luteinizing hormone (LH) radioimmunoassay (total time 4 h) has been developed and used to measure the preovulatory LH surge in 22 patients. Ovulation, assessed by laparoscopy or mini laparotomy, did not occur until at least 32 h after the start of the LH surge. This rapid LH radioimmunoassay provides a simple method of predicting ovulation for the correct timing of oocyte collection or artificial insemination.
