A Diluent for Stabilizing Tuberculin “O.T.” Diluted for the Mantoux Test

[摘要] A diluent buffered to pH 7.2 with borax and boric acid, containing 0.04 per cent gum arabic and 0.5 per cent phenol was found to stabilize tuberculins tested when diluted 1:10,000 and dispensed in rubber stoppered hard glass vials of 1 or 10 ml. capacity. This stability was proof against destruction by shaking for seven days, exposure to indirect sunlight at room temperature for four months, or prolonged transportation to warm climates and return.
