Abstract: A method for a pre-symptomatic diagnosis of a viral illness in a subject is provided. The method may include obtaining a biological sample that includes at least one peripheral blood mononuclear cell from a subject prior to the subject experiencing any symptoms associated with the viral illness. The method may further include extracting proteins from the biological sample. The method may also include analyzing the extracted proteins, via mass spectrometry, for the presence of a predefined viral protein biomarker associated with the viral illness. If the predefined viral protein biomarker is present, the subject is diagnosed with the viral illness prior to experiencing the symptoms associated with the viral illness.

Abstract: A method for a pre-symptomatic diagnosis of a viral illness includes obtaining a biological sample with a peripheral blood mononuclear cell from a subject. The method further includes stimulating the biological sample, where the stimulation of the biological sample includes adding to the biological sample a predetermined amount of antigen configured to trigger a T-cell IFN-? response in the biological sample and a predetermined amount of reagent configured to capture the T-cell IFN-? response. The method may even further include comparing the level of the T-cell IFN-? response detected in the biological sample to a control sample level, the control sample level including a control sample T-cell IFN-? response level detected in a control sample of the subject, where if the level of the T-cell IFN-? response in the biological sample is at a predetermined amount greater than the control sample level, the subject is diagnosed with the viral illness.
