In the present work, proton HR-MAS NMR spectroscopic studies have been performed on human cervical lymph nodes incisional biopsy tissues specimens, obtained from 109 patients, for the identification of metabolic fingerprints in cervical tubercular lymphadenitis. Thirty metabolites were identified. Significant decrease in myo-inositol and increase in amino acids were observed in the spectra of tubercular tissues. The proton NMR spectra were then subjected to PCA and PLS-DA multivariate analysis. The validated model allowed >98% correct classification of tubercular from non-reactive tissues when compared with gold standard histopathological examination
