A comparison of the coefficient of variation (CV% = standard deviation [SD]/mean × 100) for 6 skin test devices is shown for individual subjects [[42]] . The CVs are for the following devices: Morrow-Brown needle (MB; n = 12), bifurcated needle (BN), SN (smallpox needle; n = 12), GP (GREER “pick”; n = 12), lancet (L), and Multi-Test (MT; n = 15). Each dot may indicate >1 individual and the horizontal bars indicate mean ± SD. MT significantly greater than MB, SN and GP; p < 0.05. Adapted from Adinoff, 1989 [42].
