Abstract:
The LH color test was used to monitor 40 cycles of 32 patients. The urine test, which becomes positive at a LH-concentration of at least 50 I. U./ml, indicated the LH-peak in 34 out of 35 cycles with ascertained ovulation. In 24 cycles, the urine LH-peak preceded the serum LH-peak by one day. The urine LH-peak was found on cycle day 13.6 on average. The serum LH-peak on day 14.2 on average. The sensitivity of the LH color test was 97.2%, its specificity 100%.
