Semiquantitative analysis of CSF-VDRL and CSF-TRUST. Shadowed boxes indicate samples with identical titres of CSF-VDRL and CSF-TRUST. Open boxes indicate samples having two-fold dilution difference between CSF-VDRL and CSF-TRUST. Upward diagonals indicate CSF-VDRL-reactive, but CSF-TRUST non-reactive (n=22). Horizontal strike boxes indicate that CSF-VDRL titres are significantly higher than CSF-TRUST titres (n=5). −, Negative; CSF-TRUST, toluidine red unheated serum test on cerebrospinal fluids; CSF-VDRL, venereal disease research laboratory test on cerebrospinal fluids.
