Diagnosing LADA in Adults with "Brittle Diabetes"

A 52-year-old male presents with “brittle diabetes.” He was diagnosed three years ago with type 2 diabetes (T2DM). His A1C was 10.6% at that time. He was started on metformin and titrated up to 500 mg at breakfast and lunch and 1,000 mg at dinner. The patient is 6’0” and 161 lbs. with a BMI 21.8; BP of 128/82, and pulse of 69. Blood tests show his current A1C as 8.7%, triglycerides as 131 mg/dl, HDL as 53 mg/dl, and LDL as 97 mg/dl. Is T2DM the correct diagnosis for this patient?
