Cholesterol testing goes beyond standard assessment and may involve genetic profiling to identify the root cause of high cholesterol levels. A genetic profile can reveal if the issue is with lipid absorption or excretion, aiding in the selection of appropriate medication and treatment. Imaging techniques like a CT scan with dye injection can detect hard and soft plaque in addition to blood tests. A comprehensive approach is essential to address high cholesterol effectively, considering factors like genetic tests, apo B, insulin resistance, and individualized treatment plans.
