Varicella-zoster antibodies in adult patient with haemoblastoses.

Indirect haemagglutination (IH) antibodies to varicella-zoster (VZ) virus were investigated, under the identical conditions of a single experiment, in a group of patients with haemoblastoses and 80 normal adults of equal age groups. Statistical significance of the differences in VZ antibody geometric mean titres between the individual haemoblastoses and normal controls was examined by means of variance analysis. A significantly raised mean titre was still found in the Hodgkin's disease group.
