What it generally measures

After meals and from other sources, triglycerides circulate in the bloodstream. Labs quantify the concentration present in your sample at collection time.

Common units on reports: mg/dL

People often compare triglycerides across fasting panels to see what changed. Single values and short-term swings can reflect recent meals or other factors — your clinician interprets the full picture.
