A 46-year-old Hispanic man presented to the clinic for a routine physical and a review of his recent laboratory studies. His medical history was significant for high cholesterol.

Complete blood count, renal function and liver function tests were all normal. Additional studies included an oral glucose tolerance test (OGTT) of 157 mg/dL and hemoglobin A1c (HbA1c) of 5.9%. The patient’s physical exam was unremarkable with no abnormalities noted.

This patient has been seen every 6 months for a focused physical examination with a total cholesterol, liver function panel and a FPG to evaluate his diabetes status and cholesterol management program.
