Cholesterol results, decoded: LDL, HDL and the number nobody mentions
What a lipid panel measures, which number matters most, and when cholesterol needs treating.
By the TarragonHealth editorial team
The four numbers on the report
Total cholesterol is everything added together. LDL is the 'delivery' cholesterol that, in excess, builds up in artery walls — the one treatment usually targets. HDL is the 'cleanup' fraction, where higher is generally better. Triglycerides are circulating fat, sensitive to sugar, alcohol and weight.
The number nobody mentions: non-HDL
Subtract HDL from total cholesterol and you get non-HDL cholesterol — everything capable of clogging arteries in one figure. Many clinicians now consider it a better single measure than LDL alone, and it needs no extra test: it is arithmetic on results you already have.
There is no single 'bad' threshold
Whether a cholesterol level needs treatment depends on your whole cardiovascular risk — age, blood pressure, smoking, diabetes, family history — not the number in isolation. The same LDL can be acceptable in one person and urgent in another who has already had a heart problem.
That is why good care assesses total risk and sets a personal target, rather than reacting to a lab report line by line.
If yours is raised
Diet shifts (less fried and processed food, more fibre), weight loss and movement all help, and for people at meaningful risk, statins are among the best-evidenced, most cost-effective medicines in existence. The right answer is a risk conversation with a doctor — ideally one who will still be watching the trend next year.
