In hypersmolar hyperglycemic non ketotic coma the blood glucose level is around -: (A) 55mmol\/l, (B) 20mmol\/l, (C) 80mmol\/l, (D) 5mmol\/l
Answer is A. The laboratory features in HHS are marked hyperglycemia (plasma glucose may be >55.5 mmol/L ), hyperosmolality (>350 mosmol/L), and prerenal azotemia. In contrast to DKA, acidosis and ketonemia are absent or mild. Reference : page 2420 Harrison's Principles of Internal Medicine 19th edition
