Triglycerides optimal range and reference range
Compiled by Alina Radu, founder of Sera, from the published sources below · Last reviewed November 9, 2026
Sera's bands for Triglycerides:
- Optimal 0 – 100 mg/dL (0 – 1.13 mmol/L); sufficient 100 – 150 mg/dL (1.13 – 1.69 mmol/L); out of range below 0 or above 150 mg/dL.
Evidence grade: Established clinical threshold. A band edge that corresponds to a recognised diagnostic, risk or treatment threshold from a major clinical guideline or public-health body.
All units
| Unit | Optimal | Sufficient | Out of range |
|---|---|---|---|
| mg/dL | 0 – 100 | 100 – 150 | below 0 or above 150 |
| mmol/L | 0 – 1.13 | 1.13 – 1.69 | below 0 or above 1.69 |
What the evidence says
The upper bound is the conventional 150 mg/dL (1.7 mmol/L) threshold for a fasting sample. A non-fasting draw runs higher, and the equivalent threshold there is 175 mg/dL. The optimal band ending at 100 mg/dL is a functional target: cohort data show risk rising below 150, more clearly in men than in women, but no current guideline sets 100 as a goal.

Observational support for an optimal band ending at 100, stronger in men than in women.
What Triglycerides measures
A type of fat in your blood that is tied to your diet and metabolism.
High triglycerides are a sign of insulin resistance and metabolic problems.
