Abstract
Diagnostic/prognostic methods are provided for screening for pathologies wherein an alteration in estrogen metabolism is indicative of a pathology or a susceptibility thereto which comprise detecting and/or quantifying directly in tissues and body fluids of mammals abnormal levels of estrone metabolites and their glucuronide conjugates. Particularly preferred methods involve the use of the 16OHE1-, 2OHE1- or 2MeoE1-glucuronide fraction, i.e., the fraction which contains the metabolite and its 3-glucuronide conjugate. Methods of preparing reagents to detect said 16OHE1-, 2OHE1-, and 2MeoE1-glucuronide fraction in tissues and body fluids are disclosed as well as test kits for performing the disclosed assays.
Claims56
A method of screening for a pathology affecting estrogen-sensitive tissues of a human wherein an altered level of a metabolite of estrone and its respective 3-glucuronide is indicative of the pathology, or a susceptibility thereto, in said human which comprises:
- A. obtaining a urine, serum or tissue sample from said human in which said pathology is suspected;
- B. detecting the level of a particular metabolite of estrone and its respective 3-glucuronide from said sample;
- C. comparing this said level with the level derived from the testing of healthy humans to detect differences therefrom of said particular metabolite of estrone and its respective 3-glucuronide.
A test kit for the screening of a pathology wherein an altered level of a metabolite of estrone and its respective 3-glucuronide is indicative of the pathology or a susceptibility thereto, using the serum, tissue or body fluid medium of a human under test, comprising:
- (a) a predetermined amount of at least one detectably labeled immunochemically reactive estrone metabolite and its 3-glucoronide, or an antibody binding epitope thereof and;
- (b) directions for use of said kit.
