Triglycerides Normal Range — NCEP ATP III Thresholds
New to reading lab reports? Start with our guide to reading a blood test report
Triglycerides are the main type of fat in your blood, used for energy between meals.
Triglycerides show up on nearly every blood fat panel. The reading reflects fuel your body keeps and burns, offering a snapshot of both metabolic and heart wellbeing.
Also known as: TG, Trigs, Serum Triglycerides, TAG, Triacylglycerols
For this blood fat, lower is generally better, because high levels are linked with heart and blood-vessel risk.

What is Triglycerides?
These fat molecules pack surplus calories into a dense, storable form. After a meal your body loads them into fat tissue, then releases and burns them when fuel runs low.
Why is Triglycerides tested?
Your doctor uses them to check your metabolic and heart health. They are read as part of a full lipid (blood fats) check.
What is a normal Triglycerides range?
- India
- No India-specific national reference interval is published for this parameter; your lab's printed range is the most reliable comparison.
- Global
- Normal: <150 mg/dL; Borderline High: 150–199 mg/dL; High: 200–499 mg/dL; Very High: ≥500 mg/dL
Ranges vary by lab, method and equipment — the range printed on your own report is the one that applies to your result.

What does a Triglycerides of 150 mean?
Find your Triglycerides result in the table below, then read the band it falls into. Each band names the guideline body it comes from. Always compare against the range printed on your own report.
| If your result is | Band | Source |
|---|---|---|
| Below 150 mg/dL | Normal | NCEP ATP III (2002) |
| 150–200 mg/dL | Borderline high | NCEP ATP III (2002) |
| 200–500 mg/dL | High | NCEP ATP III (2002) |
| 500 mg/dL and above | Very high | NCEP ATP III (2002) |
Triglycerides Below 150 mg/dL — Normal
If your result is 80, 100, 120, 149 or anywhere in this band: This is the usual range for the main fat measured in blood. It is a reassuring sign when read with your other lipid results.

Worth asking your doctor
- Is this level fine for someone like me?
Triglycerides 150–200 mg/dL — Borderline high
If your result is 150, 160, 180, 199 or anywhere in this band: This is a little above the usual range. Triglycerides move a lot with recent food, alcohol and weight, so timing of the test matters.

Worth asking your doctor
- Did I fast correctly before this test?
- Which changes would bring my triglycerides down?
Triglycerides 200–500 mg/dL — High
If your result is 200, 250, 300, 400 or anywhere in this band: This is clearly above the usual range. It is worth discussing with your doctor, alongside your weight, blood sugar and habits.

Worth asking your doctor
- What is driving my raised triglycerides?
- What plan would you suggest, and when should we recheck?
Triglycerides 500 mg/dL and above — Very high
If your result is 500, 600, 800 or anywhere in this band: This is a markedly raised level. Very high triglycerides are worth discussing with your doctor without long delay.

Worth asking your doctor
- Does a very high level need attention soon?
- What tests or steps come next?

| 100 mg/dL | 1.13 mmol/L |
| 120 mg/dL | 1.35 mmol/L |
| 149 mg/dL | 1.68 mmol/L |
| 150 mg/dL | 1.69 mmol/L |
| 160 mg/dL | 1.81 mmol/L |

What does a high Triglycerides result mean?
A high level can reflect extra calories, insulin resistance, or a mix of metabolic changes. It is linked to heart risk and worth discussing with your doctor.
What does a low Triglycerides result mean?
A low level usually reflects healthy handling of fats. Very low levels are occasionally seen with poor nutrition.
What can affect your Triglycerides result?
- Refined carbs and sugar
- Alcohol intake
- Physical inactivity
- Uncontrolled diabetes
- Family history
In the Indian context
High-carbohydrate meals are common in some Indian diets and can raise triglycerides. High triglycerides often appear together with low HDL in South Asians.
Questions to ask your doctor
About this result
- What does my Triglycerides result mean for me specifically, given my age and health?
- For Triglycerides, lower is generally considered better — is my result where you would want it to be?
What to do next
- Could anything I eat, do, or take have affected my blood fat result?
- Is there anything I should do about my Triglycerides, or is it fine to leave as it is?
About retesting
- Does my Triglycerides need to be repeated, and if so, when?
- The typical range for Triglycerides can vary between labs — should I compare my result against my own lab's printed range?
The bigger picture
- Should my Triglycerides be looked at together with my LDL Cholesterol and HDL Cholesterol result?
- Does my Triglycerides connect to any condition I already have, or to anything I have noticed in how I feel?
