Lipid Panel
Use
Evaluate hyperlipidemia as an index to coronary artery disease
Special Instructions
Note that the patient's age and sex should be stated on the request form. Testing is optimal for patients with certain conditions like coronary heart disease, premature arterial disease, or family history of hyperlipidemia. In some individuals, lipid panels are recommended in the context of certain dietary and fasting conditions.
Limitations
The test has limitations in patients with obstructive liver disease as they may develop lipoprotein abnormalities. Serum lipid factors generally do not strongly influence recurrent stenosis following coronary angioplasty. LDL cholesterol cannot be calculated if triglyceride levels exceed 800 mg/dL. Additionally, some conditions may mask or alter expected lipid levels.

Specimen
Serum
Volume
1 mL
Minimum Volume
0.7 mL
Container
Red-top tube, gel-barrier tube, or green-top (lithium heparin) tube.
Collection Instructions
Separate serum or plasma from cells within 45 minutes of collection. Lipid panels are best avoided for three months following an acute myocardial infarction, although cholesterol can be measured in the first 24 hours.
Patient Preparation
Patient should be on a stable diet for ideally two to three weeks prior to collection. Fasting is not necessary but recommended if triglyceride values provide diagnostic information.
Storage Instructions
Maintain specimen at room temperature.
