Common questions

What is a normal Triglycerides level?
Optimal: < 90 mg/dL. Adult reference range.
What does a high Triglycerides mean?
A value above the reference band means Triglycerides is outside the range typical for a healthy adult. A single reading is rarely conclusive on its own — what matters is the trend across draws and the other markers around it, which is why HealthOS reads the whole panel together rather than one number at a time.
How do I improve my Triglycerides?
Cutting sugar and alcohol, exercise, omega-3 fats.
