Triglyceride senken: can a DNA test help?

A DNA test can theoretically identify genetic variants associated with elevated triglyceride levels (e.g., in APOA5, LPL, or APOE). However, the evidence is primarily from GWAS studies showing small effect sizes. Currently, no robust RCTs demonstrate that genotype-based dietary advice lowers triglycerides better than standard lifestyle recommendations (e.g., Mediterranean diet, omega-3s, exercise, weight loss). Clinical practice remains the gold standard. A DNA test may serve as a motivational tool but should not replace medical evaluation. Caveat: many direct-to-consumer tests overstate clinical relevance. Evidence is GWAS-based, not clinically validated.
