Fig. 2From: Circulating granulysin levels in healthcare workers and latent tuberculosis infection estimated using interferon-gamma release assaysSerum GNLY concentrations and interferon-gamma levels after stimulation with the TB antigens in IGRA. GNLY, granulysin; TB-Ag-stimulated interferon-gamma values, tuberculosis antigen values minus negative-control values in the blood. The scales of x- and y- axes are based on the values after logarithmic transformation of the original units; IU/ml for IGRA values and ng/ml for serum GNLY concentrationsBack to article page
