LDL to HDL ratio LDL/HDL Ratio
Your LDL divided by your HDL, the bad kind set against the good.
What it measures
The settling cholesterol divided by the clearing cholesterol.
Another view of the same balance; useful mainly for watching a trend across repeat panels.
Why it matters for how long you stay well
It has been overtaken in practice by apoB and non-HDL cholesterol, both of which carry thresholds and a clear course of action, so use those to steer the decades ahead.
How it shows up in daily life
It is arithmetic on two numbers you already have, not another test on your sample.
High and low readings
When it reads high
More settling cholesterol per unit of clearance.
When it reads low
A favourable balance.
What moves it
Daily life
- everything that moves LDL or HDL
Medicines known to shift it
- statins (lower 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.
Read it with
Markers that move this one, or that this one moves. One number read alone can mislead.
- LDL, the carrying cholesterolKnown mechanism
LDL pushes it up
This ratio is your LDL divided by your HDL. The two cholesterol numbers already carry the information, so read them rather than the ratio.
Common questions
What does LDL/HDL Ratio measure?
The settling cholesterol divided by the clearing cholesterol. Another view of the same balance; useful mainly for watching a trend across repeat panels.
What does a high LDL to HDL ratio result usually mean?
More settling cholesterol per unit of clearance.
What does a low LDL to HDL ratio result usually mean?
A favourable balance.
What is the usual reference range for LDL to HDL ratio?
A broad adult reference band is below 3. Labs differ, so read your result against the band printed on your own report.
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
- Adults
- below 3
Labs differ. The band printed on your own report is the one that applies to your result.
