Liens transversaux de livre pour 3.3.1 Materials and supplies needed
Skin test material (see above for details for each tuberculin and M. tuberculosis-specific antigen) should not be exposed to heat or light, and it should be refrigerated when not in use, but not frozen. Therefore, a cold chain needs to be maintained from production until the point of administration, and appropriate equipment (e.g. refrigerators, ice packs and coolers) must be provided. Tuberculin material should be drawn up in a syringe just before administration, and not stored over prolonged period after being drawn up in a syringe.
