Abstract
Introduction: Pregnanediol-3-glucuronide (PdG), as the main metabolite of progesterone in urine, plays a significant role in the prediction of ovulation, threatened abortion, and menstrual cycle maintenance. Methods: To achieve a rapid and sensitive assay, we have designed a competitive model-based time-resolved fluorescence microsphere-lateral flow immunochromatography (TRFM-LFIA) strip. Results: The optimized TRFM-LFIA strip exhibited a wonderful response to PdG over the range of 30-2,000 ng/mL, the corresponding limit of detection (LOD) was calculated as low as 8.39 ng/mL. More importantly, the TRFM-LFIA strip was innovatively used for the quantitative detection of PdG in urine sample, and excellent recovery results were also obtained, ranging from 97.39% to 112.64%. Discussion: The TRFMLFIA strip possessed robust sensitivity and selectivity in the determination of PdG, indicating the great potential of being powerful tools in the biomedical and diagnosis region.

Abstract
OBJECTIVE The purpose of this study was to evaluate changes in cervicovaginal fluid characteristics to identify ovulation. STUDY DESIGN Several ovulation indicators were studied in a university-based natural family planning center. Fifteen parous women during 29 ovulatory cycles detected cervicovaginal fluid at the vulva. They self-aspirated their upper vaginal fluid, described it, and kept it for later checking. They also took basal body temperature, collected timed first morning urine samples for estrone and pregnanediol glucuronide enzyme immunoassays, and submitted to serial ovarian transvaginal ultrasound scans. RESULTS Considering a +/-1-day period since ultrasound ovulation detection or allowing an extra day (-1 to +2), women perceived ovulation from cervicovaginal fluid at the vulva in 76% or 97% of cycles, on the basis of their visual description of vaginally extracted fluid in 76% or 90%, which rose to 90% or 97% for the instructor's description, and in 76% or 86% with a rapid drop in glucuronide ratio. Basal body temperature was less precise (71% or 79%). CONCLUSION Evaluation of cervicovaginal fluid changes is an accurate ovulation indicator.
