Triglycerides
Triglycerides are the main form of fat in the blood. They depend strongly on the last meal, so the test is taken fasting.
At a glance
- Sample
- Blood
- Units
- mg/dL (US), mmol/L (Europe)
- Often looked at with
- Total cholesterol, LDL cholesterol, HDL cholesterol
- Preparation
- Labs often ask for 8–12 hours without food, so the lipid panel is taken in the morning; water only. Some labs also accept it non-fasting.
Units: mg/dL and mmol/L
US labs usually print triglycerides in mg/dL, most European labs in mmol/L. To convert, divide mg/dL by 88.57.
mmol/L = mg/dL ÷ 88.57 · molar mass 885.7 g/mol
This converter changes units only. It doesn’t tell you whether a number is in or out of any range: that depends on the range printed by your own lab, and on your doctor. Soma does not diagnose and is not medical advice.
Why lab ranges differ
Each lab sets its reference range for its own method and analyser, and many ranges differ by age and sex. Two labs can print different ranges for the same blood, so a result is read against the range on its own report, not against a number from another lab or a website.
Soma charts every triglycerides result against the range printed by the lab that measured it.
What can affect the result
- Food less than 9–12 hours before the test raises them a lot.
- Alcohol the day before.
- A heavy dinner the night before.
If something like this applies, mention it to the doctor who reads your results.
Questions
How do I convert triglycerides from mg/dL to mmol/L?
Divide mg/dL by 88.57. For example, 150 mg/dL is 1.69 mmol/L.
Why does my lab’s triglycerides range differ from another lab’s?
Each lab sets its range for its own method and equipment, and many ranges differ by age and sex. That’s why a result is best read against the range printed on the same report.
How do I prepare for a triglycerides test?
Labs often ask for 8–12 hours without food, so the lipid panel is taken in the morning; water only. Some labs also accept it non-fasting. Follow your lab’s instructions.
