What LDL Cholesterol tells you
Lipid and inflammation markers that clinicians may consider as part of a long-term heart-health picture, alongside other factors and clinical judgement.
Which Honed panels include LDL Cholesterol
LDL Cholesterol is measured in the Essential Panel and Performance Panel. Every sample is collected at a pathology collection centre and processed at a NATA-accredited laboratory against NHFA reference ranges, with personalised plain-English commentary in your secure online report.
Why LDL Cholesterol matters
Low-density lipoprotein (LDL) cholesterol is the primary form of cholesterol transport in the blood, often called "bad cholesterol" because elevated LDL is associated with plaque deposition in arteries. LDL is synthesized by the liver and also obtained from dietary sources. In the context of overall cardiovascular health, LDL is interpreted alongside HDL, triglycerides, and inflammatory markers by a clinician. The size and density of LDL particles also matter (small, dense LDL particles are more atherogenic than large, buoyant particles).
The range explained
Low levels
Low LDL cholesterol (below 1.8 mmol/L) is generally considered desirable and associated with lower cardiovascular risk.
Normal range
Reference range: 1.8–3.4 mmol/L is often considered optimal to desirable depending on individual risk factors. Clinicians may recommend lower targets for those with cardiovascular disease or risk factors.
High levels
Elevated LDL cholesterol (above 3.4 mmol/L) may increase cardiovascular risk, particularly when accompanied by low HDL or elevated triglycerides.
What affects LDL Cholesterol
- Training: Regular exercise, particularly aerobic training, can lower LDL and improve the lipid profile.
- Nutrition: Saturated fat and dietary cholesterol elevate LDL; fibre (especially soluble fibre from oats and legumes), plant sterols, and polyunsaturated fats lower LDL. Body weight management also supports lower LDL.
- Sleep: Sleep deprivation can elevate LDL cholesterol.
- Stress: Chronic stress can elevate LDL through multiple pathways.
When to retest
Every 12 months for general health; more frequently if elevated or if lifestyle changes are made.
Why athletes care
While LDL is not directly performance-limiting, maintaining healthy LDL supports cardiovascular health and longevity for athletes.
