FIG. 3. — Typical results of ELISPOT assay with PBMCs and CSF MCs from patients with tuberculous meningitis (A and B) and aseptic meningitis (C and D). A response was classified as indeterminate if the number of spots for the positive control well was less than 20 or the number of spots for the negative control well was more than 10. A response was classified as positive if the number of spots for ESAT-6 or CFP-10 was six or more after subtraction of the background spots in the negative control well.
