Method for measuring tear constituents in a tear sample

Abstract

The present invention provides a method, wherein the method classifies a subject as suffering from dry eye, the method consisting of: a. obtaining demographic data, consisting of the age and gender of the subject; b. obtaining a tear sample from the patient, and determining the level of human serum albumin; c. from the determined level of human serum albumin, assigning a score for the determined amount of human serum albumin; and d. from the assigned score, calculating a cutoff probability score, according to the following equation: exp ⁡ ( - 0.6491 - 1.1142 * Albumin ) 1 + exp ⁡ ( - 0.6491 - 1.1142 * Albumin ) wherein the subject has dry eye, if the calculated cutoff probability score is from 50% to 60%.
