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
The readings are interpreted as follows:
|<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|
|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|
|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|
|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)
