Plasma concentrations of pregnancy-associated alpha-2-glycoprotein in patients with leukaemia.

Plasma concentrations of pregnancy-associated alpha 2-glycoprotein (alpha 2-PAG) were estimated by electroimmunoassay in 64 patients with various leukaemias. 7% (2/30) of male patients and 28% (9/32) of female patients had alpha 2-PAG levels above the established upper limit for age- and sex-matched controls. There was no indication that these elevated alpha 2-PAG concentrations were related to type of leukaemia ana no correlation between the circulating levels of alpha 2-PAG and the absolute lymphocyte or monocyte counts was found.
