Abstract
Estimation of the cholesterol content of blood plasma is now part of the routine management of the diabetic patient in the Montreal General Hospital. Estimations are made at least on the admission of patients to the hospital and on their discharge and thereafter as regularly as possible, on their return to the clinic for the treatment for diabetes. All estimations are made on blood obtained from patients in the fasting state at least fifteen hours after the evening meal. Should patients require insulin, tests are made, as for blood sugar, not only before food is given, but before the administration of this drug. The present report is concerned with the study of 2,000 estimations made in 385 cases. All tests were made, not only under these standard conditions, but by the same technic and by the same laboratory workers. Patients observed for periods of less than six months are excluded
