Abstract To examine the accuracy of five different at-home ovulation predictor kits (OPKs), and to understand patient experience with the use of those kits. Prospective cohort study. Patients with regular menses undergoing monitored natural cycle frozen embryo transfer, timed intercourse, and intrauterine insemination cycles involving daily blood luteinizing hormone (LH) level monitoring between 2022 and 2024. Use of five commercially available OPKs for the first 5 days of blood LH level monitoring with a daily experience survey. The primary outcome was the accuracy of the OPKs defined as concordance between test results (positive or negative) and blood LH level (above or below 25 mIU/mL). Secondary outcomes included positive predictive value, negative predictive value, sensitivity, and specificity of OPK surge detection. We also examined patient reports regarding the clarity of kit instructions, confidence in kit results, and likelihood of future purchase and use. A total of 23 patients completed 97 total days of OPK testing, and 13 patients had a documented blood LH surge during their testing. Ovulation predictor kit surge detection accuracy compared with blood LH surge was similar across the five kits (Easy@Home, 95.88%; Wondfo, 94.85%; Pregmate, 96.90%; Clearblue, 91.75%; and Clinical Guard, 91.75%). Sensitivity was slightly better for Easy@ Home (75.00%), Wondfo (69.23%), and Pregmate (76.92%) than for Clearblue (61.54%) and Clinical Guard (38.46%). There were no clinically significant differences between the five OPKs regarding positive predictive value, negative predictive value, or specificity of surge detection. Participant experience was qualitatively similar across all five OPKs, with exception of slightly fewer patients reporting that they were likely to purchase and use Clinical Guard again in the future. All five tested-at-home one-step OPKs were highly accurate and performed similarly regarding patient experience despite variations in price. Precisión y experiencia de pacientes similar con diferentes kits de predicción de la ovulación. Analizar la precisión de cinco kits de predicción de la ovulación (OPK) de uso doméstico, y conocer la experiencia de los pacientes con su uso. Estudio de cohorte prospectivo. Una única consulta de asesoramiento en fertilidad. Pacientes con menstruaciones regulares sometidas a ciclos naturales monitorizados de transferencia de embriones congelados, coito programado y ciclos de inseminación intrauterina que incluyeron monitorización diaria del nivel sérico de hormona luteinizante (LH) entre 2022 y 2024. Uso de cinco OPK comerciales durante los primeros 5 días de monitorización del nivel de LH en sangre con una encuesta diaria. El principal resultado fue la precisión de las OPK, definida como la concordancia entre los resultados del test (positivo o negativo) y el nivel de LH en sangre (por encima o por debajo de 25 mUI/mL). Los resultados secundarios incluyeron valor predictivo positivo, valor predictivo negativo, sensibilidad y especificidad de la detección de los OPK. También se analizaron las respuestas de pacientes sobre la claridad de las instrucciones, la confianza en los resultados y probabilidad de compra y uso en el futuro de estos kits. Un total de 23 pacientes completaron 97 días totales de pruebas OPK, y 13 pacientes tuvieron un aumento documentado de LH en sangre durante su utilización. La precisión de detección del aumento de LH en el kit en comparación con el aumento de LH sérico fue similar en los cinco kits (Easy@Home 95,88%; Wondfo 94,85%; Pregmate 96,90%; Clearblue 91,75%; y Clinical Guard 91,75%). La sensibilidad fue ligeramente superior para Easy@Home (75,00%), Wondfo (69,23%) y Pregmate (76,92%) que para Clearblue (61,54%) y Clinical Guard (38,46%). No hubo diferencias clínicamente significativas entre las cinco OPK en cuanto al valor predictivo positivo, valor predictivo negativo o especificidad. La experiencia de los participantes fue cualitativamente similar en los cinco OPK, con la excepción de un número ligeramente inferior de pacientes que afirmaron que era probable que compraran y utilizaran nuevamente Clinical Guard en el futuro. Las cinco OPK probadas fueron muy precisas y tuvieron un comportamiento similar en cuanto a la experiencia del paciente a pesar de las variaciones de precio.
