A doctor personally takes a low dose of Rosuvastatin (5mg) to proactively lower his LDL cholesterol below 60 mg/dL.

The medical literature suggests the optimal LDL cholesterol level is what we have at birth, around 20-40 mg/dL.

Even in people with no other risk factors, blockages still form in blood vessels if LDL cholesterol levels rise above 60 mg/dL.

An APOB test is a more precise measure of heart disease risk than standard LDL cholesterol because it counts the number of harmful lipoprotein particles.

Everyone should get their Lipoprotein(a) level tested at least once in their adult life, as it's a major genetic risk factor for heart disease unaffected by diet or exercise.

For healthy people on a good diet, there is no advantage to routinely testing vitamin D levels as it doesn't change outcomes.

An engineering philosophy, 'the best part is no part,' can be applied to medicine to avoid unnecessary tests that don't improve health outcomes.

For preventative screening in non-diabetics, an HBA1C test is more clinically useful than insulin tests or continuous glucose monitors.
