It has been found that a urine test for ovarian reserve can be provided which is equivalent in sensitivity to current laboratory methods which determine ovarian reserve based on FSH levels in serum. A lateral flow device for indicating ovarian reserve is disclosed. The device has an application zone for receiving a urine sample, a labelling zone containing label which binds to FSH in the sample, and a detection zone where FSH-bound label is retained. The detection zone has a threshold value which corresponds to a serum FSH level of between 5-20 mIU/ml (e.g. 10mIU/ml). A test result above the threshold value indicates diminished ovarian reserve.

Il a été établi qu'un test urinaire permettant de déterminer la réserve ovarienne équivaut en sensibilité à des procédés de laboratoire courants qui déterminent la réserve ovarienne en se fondant sur les niveaux de FSH contenus dans le sérum. L'invention concerne également un dispositif à flux latéral destiné à indiquer la réserve ovarienne. Ce dispositif comporte une zone d'application destinée à recevoir un échantillon d'urine, une zone de marquage contenant un marqueur qui se lie à la FSH et une zone de détection au niveau de laquelle le complexe marqueur-FSH est retenu. La zone de détection présente une valeur seuil correspondant au niveau de FSH dans le sérum compris entre 5 et 20 mIU/ml (à savoir 10mIU/ml). Un résultat supérieur à la valeur seuil indique une réserve ovarienne diminuée.
