Q

A blood specimen is drawn for lipoprotein phenotyping. The test results obtained are
Triglyceride, 235 mg/dL (reference range, 40-164 mg/dL)
Total cholesterol, 190 mg/dL(reference range, less than 200 mg/dL)
Prebeta lipoprotein fraction increased
Beta lipoprotein fraction normal
Chylomicrons present
Serum appearance milky
The best explanation for these results would be that the individual exhibited characteristics of
• Type 1 hyperlipoproteinemia
• Type 11 hyperlipoproteinemia
• Type 1V hyperlipoproteinemia
• Type 1 hyperlipoproteinemia & Type 11 hyperlipoproteinemia
• A normal individual

A
