Fss. Alani et al., PSEUDOHYPERKALEMIA ASSOCIATED WITH HEREDITARY SPHEROCYTOSIS IN 4 MEMBERS OF A FAMILY, Postgraduate medical journal, 70(828), 1994, pp. 749-751
Pseudohyperkalaemia was detected in four members of a family all of wh
om have hereditary spherocytosis with normal white blood cells and pla
telets counts. The degree of pseudohyperkalaemia was related to the ti
me between sampling and cell separation, and inversely related to the
temperature in which the sample was left to stand before cell separati
on. A fifth member of this family was free from both conditions. The a
ssociation suggests linkage at a membrane level.
