Elispot Igra With Purified Protein Derivative Stimulation For Diagnosing Nontuberculous Mycobacterial Cervical Lympadenitis.

Childhood cervical lymphadenitis caused by nontuberculous mycobacteria is a diagnostic challenge for the clinician. We present a new promising diagnostic method for childhood nontuberculous mycobacterial lymphadenitis. The modified T-SPOT.TB test with purified protein derivative as an additional antigen is noninvasive with estimated sensitivity and specificity of 1.00 and 0.81, respectively.
