Positive Multi-Test reactions do not cause false positive reactions at adjacent sites.
To answer the question of whether proximity of Multi-Test skin test sites causes false positive reactions, 50 subjects with prior 4+ skin test responses were retested with antigens and ten additional subjects were tested with histamine (1.8 mg/mL). No positive readings occurred at any of the replicate saline control sites adjacent to 3+ or 4+ allergen sites or to 3+ histamine reactions.
