A 67-year-old woman is referred for treatment of hyperlipidemia. Her cholesterol and triglycerides are high, despite treatment with lipid-lowering medication. She is noted to have hair loss and hoarseness to her voice. She also complains of cold intolerance and fatigue. The physician orders a BMP, lipid panel, and thyroid testing cascade. Results are as follows:

Analyte 2/19/2018 09:50 . Reference Range

Na 141 . 135-145 mEq/L

K 4.1 . 3.5-5.0 mEq/L

Cl 101 . 95-105 mEq/L

CO2 25 . 22-28 mEq/L

Glucose 103 . 70-100 mg/dL

BUN 8 . 7-20 mg/dL

Creat 0.4 . 0.5-1.1 mg/dL

BUN/Creat Ratio 20 . 10-20

Total Cholesterol 250 . 150-200 mg/dL

LDL 147 . <100 mg/dL

HDL 41 . 40-80 mg/dL

Triglycerides 310 . <150 mg/dL

TSH 43 . 0.4-4.5 mIU/L

fT4 0.4 . 0.8-2.4 ng/dL

tT3 Not Indicated . 80-180 ng/dL
