Triglyceride Levels: Normal, High & Very High
Triglyceride reference ranges come from large population studies (NHANES, WHO). They provide a framework for interpreting your results, but your personal health context matters most. Normal <150 mg/dL. High 200-499. Very high ≥500. These values are current for 2026 and reviewed periodically to keep you informed.

How it works
1 min readTriglyceride reference values come from large population studies (NHANES, WHO, CDC). They vary by age, sex, ethnicity, and region. They're guidelines only — your personal medical history always takes precedence.
How It's Calculated
Normal <150 mg/dL. High 200-499 mg/dL. Very High ≥500 mg/dL.
This calculator applies the standard classification to your values, checking typical ranges and alerting you to any unusual results.
Adult Reference Ranges
| Measurement | Normal Range |
|---|---|
| Blood Pressure | <120/80 mmHg |
| Resting Heart Rate | 60-100 bpm |
| Body Temperature | 36.1-37.2°C |
| Blood Oxygen (SpO2) | 95-100% |
| Fasting Glucose | 70-100 mg/dL |
| HbA1c | <5.7% |
| Total Cholesterol | <200 mg/dL |
| LDL Cholesterol | <100 mg/dL |
| HDL Cholesterol | >40 (M) / >50 (F) |

Frequently asked questions
What are normal triglyceride levels?
Normal is less than 150 mg/dL, borderline high is 150-199, high is 200-499, and very high is 500 mg/dL or above.
How often should I get my triglycerides tested?
The American Heart Association recommends testing at least every 4-6 years for healthy adults. More frequent testing is needed if you have risk factors.
What's the difference between high and very high triglycerides?
High triglycerides (200-499) increase cardiovascular risk, while very high (≥500) significantly increases risk of pancreatitis and heart disease.
Can I have high triglycerides without symptoms?
Yes. High triglycerides are often asymptomatic. Regular blood work is important, especially if you have family history or risk factors.
Do triglyceride levels differ by age?
Yes. Triglyceride levels typically increase with age. Normal ranges vary between children, adults, and older adults.
What medications affect triglyceride levels?
Statins, beta-blockers, diuretics, corticosteroids, and some diabetes medications can affect triglycerides. Always inform your doctor of all medications during testing.
What can lower triglycerides naturally?
Regular exercise, reducing refined carbs and sugar, limiting alcohol, maintaining a healthy weight, and eating omega-3 rich foods help lower triglycerides.
When should I see a doctor about triglyceride results?
See your doctor if results are above 200 mg/dL, if you have symptoms, or if you have family history of heart disease or metabolic disorders.
