US Classification:

435 71, 5303911, 5303913

Abstract:

The present invention provides a method for predicting the likely timing of the onset of menopause for a perimenopausal female subject by determining the amount of hLHβcf in a sample from the subject comprising the steps of: (a) contacting a sample from the subject with an antibody which specifically binds to hLHβcf without substantially cross-reacting with hLH, hLHβ or hLHβcf, under conditions permitting formation of a complex between the antibody and hLHβcf; (b) measuring the amount of complex formed, so as to thereby determine the amount of hLHβcf in the sample; and (c) comprising the amount of hLHβcf in the subject's sample determined in step (b) with either (i) the amount determined for known postmenopausal female subject or (ii) the amount determined for a sample from a known premenopausal female subject, wherein an amount of hLHβcf in the sample similar to the amount of hLHβcf in the known postmenopausal sample indicates temporal proximity to the onset of menopause, and an amount of hLHβcf in the sample similar to the amount of hLHβcf in the known premenopausal sample indicates temporal distance from the onset of menopause for the subject. AS described herein amount is both concentration and pattern of measurement of concentrations in one or more consecutive urine specimens.
