The atherogenic index of plasma is the base ten logarithm of triglycerides divided by HDL, a compact marker of the small dense LDL pattern.

What the log ratio captures
High triglycerides with low HDL signal that LDL particles are being remodeled into smaller, denser, more artery invasive forms. The log transform turns that exchange into a single number.
Understanding your result
- Below 0.11 corresponds to the low risk pattern
- 0.11 to 0.21 is intermediate
- Above 0.21 marks the high risk small dense pattern
Why add it to a panel
Standard LDL cholesterol counts cholesterol mass, not particle size. Two people with identical LDL can carry very different particle patterns, and AIP separates them cheaply.
Improving the ratio
The same levers that lower triglycerides and raise HDL apply, namely weight loss, movement after meals, fewer refined carbs and no smoking.
