HDL to LDL ratio HDL/LDL Ratio
Your HDL divided by your LDL, the same two numbers the other way round.
What it measures
The clearing cholesterol divided by the settling cholesterol.
Nothing your LDL, HDL and ApoB do not already tell you; higher is better, but no consensus cut-off exists.
Why it matters for how long you stay well
Like the other cholesterol ratios it carries no guideline target, so the long game is played on apoB and non-HDL rather than here.
How it shows up in daily life
It is the same pair of results flipped over, so a higher number here is the favourable direction.
High and low readings
When it reads high
A higher value is the favourable direction.
When it reads low
Less clearing cholesterol per unit of settling cholesterol.
How to read itRead alongside LDL and HDL themselves - it is the LDL/HDL ratio turned upside down and carries no separate target.
What moves it
Daily life
- everything that moves LDL or HDL
Medicines known to shift it
- statins (raise it)
Listed so a result can be read in context. It is not advice to start, stop or change any medicine; that decision belongs with your physician.
Common questions
What does HDL/LDL Ratio measure?
The clearing cholesterol divided by the settling cholesterol. Nothing your LDL, HDL and ApoB do not already tell you; higher is better, but no consensus cut-off exists.
What does a high HDL to LDL ratio result usually mean?
A higher value is the favourable direction.
What does a low HDL to LDL ratio result usually mean?
Less clearing cholesterol per unit of settling cholesterol.
Is there a reference range for HDL to LDL ratio?
There is no standalone band. Read alongside LDL and HDL themselves - it is the LDL/HDL ratio turned upside down and carries no separate target.
Educational only, not a diagnosis. A single number means little without your history and the rest of your panel, so discuss your own results with your physician.
Typical adult reference band
No standalone band; read it with the markers named on this page.
Labs differ. The band printed on your own report is the one that applies to your result.
