Summary
Erythema is an essential part of the contact reaction and can be quantified by laser Doppler flowmetry, which records skin blood flow. Healthy subjects were exposed to solvents and nicotinates for different periods of time and the skin test sites were then assessed by laser Doppler flowmetry as well as by the naked eye. It is concluded that the naked eye cannot detect erythema until the skin blood flow has increased three to four times.
