How reports print it
What it shows
High-density lipoprotein cholesterol: the part of cholesterol that HDL particles carry from tissues to the liver.
Units and conversion
Base unit: mmol/L.
- 1 mg/dL = 0.02586 mmol/L · 1 mmol/L = 38.67 mg/dL
Typical ranges
Your laboratory’s range comes first — it is printed on the report next to the result. Below is one laboratory’s adult range with its method: a reference, not a rule.
| Who | Range, mmol/L |
|---|---|
| Men | > 1 |
| Women | > 1.2 |
Range source: Лаборатория Хеликс — Холестерол – липопротеины высокой плотности (ЛПВП)
Good to know
