Reference ranges for adults; interpretation and treatment decisions belong with your clinician.
Why the ratio
Total cholesterol alone hides the split between LDL (delivers cholesterol to artery walls) and HDL (hauls it back). The total-to-HDL ratio captures the balance: under 3.5 is ideal, over 5 signals elevated cardiac risk — sometimes despite a 'normal' total.
Moving the numbers
LDL responds most to saturated-fat reduction and statins; HDL rises with exercise and falls with smoking; triglycerides track sugar, alcohol, and weight. Modern guidelines increasingly emphasize ApoB and LDL directly, but the ratio remains a solid first-pass screen.
