Interpretation and Management of Non-HDL Cholesterol of 122 mg/dL
A non-fasting non-HDL cholesterol of 122 mg/dL is excellent and requires no lipid-lowering therapy in most patients, as it falls well below the treatment threshold of 130 mg/dL for moderate-risk individuals and even below the 100 mg/dL goal for very high-risk patients. 1
Risk-Based Interpretation Framework
Your non-HDL cholesterol level should be interpreted according to your absolute cardiovascular risk category, which determines whether this value represents adequate control or requires intervention 2:
Very High-Risk Patients (Established ASCVD, diabetes with ASCVD)
- Target non-HDL-C: <100 mg/dL 2
- Your level of 122 mg/dL exceeds this goal by 22 mg/dL
- If you fall into this category, intensification of lipid-lowering therapy is warranted 2
High-Risk Patients (10-year ASCVD risk ≥20%)
- Target non-HDL-C: <130 mg/dL 1, 2
- Your level of 122 mg/dL is 8 mg/dL below this goal
- No additional therapy needed if you are in this risk category 2
Moderate-Risk Patients (10-year ASCVD risk 7.5-20%)
Lower-Risk Patients (10-year ASCVD risk <7.5%)
- Target non-HDL-C: <160 mg/dL (LDL-C goal +30 mg/dL) 1
- Your level of 122 mg/dL is well below this threshold
- No intervention required 2
Clinical Context and Advantages of Non-HDL Cholesterol
Non-HDL cholesterol captures all atherogenic lipoproteins including VLDL, IDL, LDL, and lipoprotein(a), making it a comprehensive measure of cardiovascular risk 1:
- Non-fasting measurement is valid: Unlike LDL-C, non-HDL-C does not require fasting and maintains accuracy regardless of triglyceride levels 1
- Superior predictive value: Non-HDL-C predicts cardiovascular events as well as or better than LDL-C across multiple populations 1, 3, 4
- Particularly valuable when triglycerides are elevated: Non-HDL-C accounts for triglyceride-rich remnant particles that LDL-C misses 1, 5
Management Algorithm Based on Your Result
Step 1: Determine your 10-year ASCVD risk using the Pooled Cohort Equations (age, sex, race, total cholesterol, HDL-C, systolic blood pressure, diabetes, smoking) 2, 6
Step 2: Compare your non-HDL-C of 122 mg/dL to risk-based targets:
- If very high-risk (established ASCVD): Your 122 mg/dL exceeds the <100 mg/dL goal → initiate or intensify statin therapy 2
- If high or moderate-risk: Your 122 mg/dL meets the <130 mg/dL goal → continue current therapy, no escalation needed 1, 2
- If lower-risk: Your 122 mg/dL is well below threshold → no pharmacologic intervention required 2
Step 3: If you are already on statin therapy and have achieved non-HDL-C <130 mg/dL, verify that your LDL-C is also at goal (typically <100 mg/dL for high-risk, <70 mg/dL for very high-risk) 2
Step 4: Maintain therapeutic lifestyle changes regardless of medication status 2:
- Saturated fat <7% of total calories 2
- Dietary cholesterol <200 mg/day 2
- Trans fat <1% of total energy 2
- Soluble fiber >10 g/day 2
- ≥150 min/week moderate-intensity aerobic activity 2
Common Pitfalls to Avoid
Do not initiate statin therapy based solely on non-HDL-C of 122 mg/dL without assessing overall cardiovascular risk 2. This value is favorable in most risk categories and does not automatically warrant treatment 1.
Do not assume this single favorable value eliminates cardiovascular risk. You must still assess LDL-C, blood pressure, diabetes status, smoking, and family history to determine overall risk 2, 6.
Do not ignore this result if you have established cardiovascular disease. In very high-risk patients, a non-HDL-C of 122 mg/dL exceeds the <100 mg/dL goal and requires therapy intensification 2.
Follow-Up Recommendations
- If not on lipid-lowering therapy: Recheck fasting lipid panel annually if you have risk factors, or every 4-5 years if low-risk 6
- If on statin therapy: Recheck lipids 4-8 weeks after any dose adjustment to confirm adequate response 2
- If very high-risk with non-HDL-C 122 mg/dL: Consider adding ezetimibe 10 mg daily or intensifying statin dose to achieve non-HDL-C <100 mg/dL 2
