Calculation steps

  1. 1Friedewald: LDL = TC − HDL − TG/2.2 = 5 − 1.3 − 1.5/2.2 = 3.02 mmol/L
  2. 2Non-HDL = TC − HDL = 3.70 mmol/L (target < 3.4)
  3. 3TC/HDL ratio = 3.85 (< 4 ideal, > 5 high risk)

Reference standards (mmol/L)

Total cholesterol TC< 5.2 desirable5.2–6.19 borderline≥ 6.2 high
LDL-C< 3.4 desirable3.4–4.09 borderline≥ 4.1 high (<1.8 for very-high-risk)
HDL-C≥ 1.0 normal—< 1.0 low
Triglycerides TG< 1.7 desirable1.7–2.29 borderline≥ 2.3 high
Lipid tests require a 12-hour fast; a single abnormal result should be re-checked in 1-2 weeks before any conclusion. LDL targets depend on your risk profile: <3.4 for general population, <2.6 with diabetes/hypertension, <1.8 after cardiovascular events. Statins and other medications must follow medical advice — this tool is for reference only.
