A. Diagnosis of metabolic syndrome; waist circumference, HDL-C, and fasting blood glucose meet the criteria B. Diagnosis of metabolic syndrome; waist circumferenc In this scenario, waist circumference, triglyceride level, and fasting blood glucose meet the criteria for diagnosis of metabolic syndrome. NCEP: ATP III criteria for diagnosis of metabolic syndrome is the presence of three or more of these components: Abdominal obesity: Increased waist circumference Men: > 40 inches Women: > 35 inches Elevated triglycerides > 150 mg/dL or drug treatment for elevated triglycerides Reduced HDL-Cholesterol (HDL-C) Men: < 40 mg/dL Women: < 50 mg/dL Elevated blood pressure > 130/85 mm Hg or drug treatment for elevated blood pressure Elevated fasting glucose > 100 mg/dL or drug treatment for elevated glucose LDL-C is not used as a determining factor in diagnosis of metabolic syndrome with the NCEP guidelines.

Ringed sideroblast The cell indicated by the arrow is a ringed sideroblast. If siderotic granules form a ring around at least half the periphery of the nucleus of a nucleated red blood cell, the cell is referred to as a ringed sideroblast.
