The present disclosure is directed toward methods for obtaining and processing ocular fluid samples from a subject in preparation for further analysis for diagnostic purposes. Ocular fluid provides a superior sample medium for biomarker analysis as compared to other biological media such as blood, serum, saliva, urine or bodily secretions. Proper sample collection and processing is critical for further use as a diagnostic medium as studies have shown that biomarkers found in ocular fluid can degrade quickly if mishandled.
