Actual (reported)BCG Uptake
Change in concentration of interferon (IFN) gamma levels in blood after Bacille Calmette-Guérin (BCG) incubation relative to baseline as measured by SFUs. Spot forming units (SFU) is a measure of immune response of mononuclear cells in response to M. avium lysate. Higher values indicate a stronger immune response.
