[Immunobiological means of identifying hypersensitivity to anesthetics and adjuvants]

The diagnosis of hypersensitivity to anesthetics and adjuvants is based chiefly on immunobiological tests which involve:-sensitized lymphocytes; -IgE or IgG antibodies; -sensitized target cells; -determination of chemical mediators. Comparison between these different methods is only possible for techniques involving the sensitized lymphocyte, such as the LTT and EA rosettes for examples, or T.D.B.H. and liberation of histamine. Comparison between the LTT and RAST is difficult, since the first technique investigates the sensitized lymphocyte while the second involves radio-immune antibody assay. An attempt to establish a correlation between these two types of methods is difficult but they can, however, complement each other.
