• Diagnosis of Lipid Disorders

    Lipid disorders are diagnosed with blood tests that measure the level of cholesterol and triglyceride in the blood.
    Cholesterol levels are checked with a blood test. A small blood sample is taken from a vein in your arm. You may need to fast for several hours, usually overnight, before your blood is taken. The test measures levels of:
    • Total cholesterol
    • LDL (bad) cholesterol
    • HDL (good) cholesterol
    • Triglycerides
    The readings are interpreted as follows:
    Level Interpretation
    <200 mg/dL (5.2 mmol/L) Desirable
    200-239 mg/dL (5.2-6.1 mmol/L) Borderline high
    240 mg/dL (6.2 mmol/L) and above High
    Level Interpretation
    less than 100 mg/dL (2.6 mmol/L) Optimal
    100-129 mg/dL (2.6-3.3 mmol/L) Near optimal/above optimal
    130-159 mg/dL (3.4-4.0 mmol/L) Borderline high
    160-189 mg/dL (4.1-4.8 mmol/L) High
    >190 mg/dL (4.9 mmol/L) and above Very high
    Level Interpretation
    60 mg/dL (1.6 mmol/L) and above Protective against heart disease
    less than 40 mg/dL (1.0 mmol/L) A major heart disease risk factor
    Level Interpretation
    less than 150 mg/dL (1.7 mmol/L) Normal
    150-199 mg/dL (1.7-2.2 mmol/L) Borderline high
    200-499 mg/dL (2.3-5.6 mmol/L) High
    500 mg/dL (5.7 mmol/L) and above Very high
    mg/dL = milligrams per deciliter of blood (mmol/L= millimoles per liter of blood)
