We have tested an easy and rapid "matrix cushion test" for qualitative determination of U-pregnandiol-3 alpha-glucuronide (U-PGD). The specificity of the test is high, the sensitivity is 4.0 microM, the inter-analysis variation is low as in 96% of the double determinations, agreement was present between the first and second analyses. A positive result on the 21st of the menstrual cycle indicates that ovulation has occurred while this cannot be exluded by a negative or doubtful result. If demonstration of a functioning corpus luteum is also required, the urine should be diluted 1:2 with tap water.
