RT Journal Article SR Electronic T1 Raised Coulter mean corpuscular volume in diabetic ketoacidosis, and its underlying association with marked plasma hyperosmolarity JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 334 OP 336 DO 10.1136/jcp.36.3.334 VO 36 IS 3 A1 LA Evan-Wong A1 RJ Davidson YR 1983 UL http://jcp.bmj.com/content/36/3/334.abstract AB An abnormal and transient increase of the Coulter mean red cell volume (MCV) was observed in four of 10 patients with diabetic decompensation. A sequential study of haematological and biochemical measurements in these patients revealed that this phenomenon was associated with the hyperosmolar state. The proposed mechanism and the clinical implications of this change are briefly discussed.
