Laboratory Studies
- Measure plasma lipid and lipoprotein levels while the patient is on a regular diet after an overnight fast of 12-16 hours. Abnormal lipoprotein patterns can often be identified after determining serum cholesterol and triglyceride levels and visual inspection of the plasma sample (stored at 4°C).
- In some cases, performing electrophoresis and ultracentrifugation of whole plasma specimens may be necessary to help establish a diagnosis.
Imaging Studies
- Ophthalmologists generally do not order imaging studies.
