BLOOD TEST · SMART CARE POLYCLINIC, DEIRA
Lipid Profile explained
The fats in your blood — total cholesterol, LDL, HDL and triglycerides — used to estimate cardiovascular risk.
What the Lipid Profile measures
Cholesterol travels in particles. LDL deposits it into artery walls; HDL carries it away. Triglycerides are a separate fat that rises sharply with sugar, alcohol and weight. What a given set of numbers means for your cardiovascular risk — and whether it warrants treatment — follows the joint ACC/AHA dyslipidaemia guideline rather than a single cut-off.1
What the result tells you
LDL is the treatment target
It narrows arteries silently over decades and causes no symptoms until a heart attack or stroke. That is the entire reason it is screened rather than waited for.
No number decides anything alone
Risk is judged from LDL alongside blood pressure, blood sugar, smoking, weight, age and family history. Identical cholesterol can warrant opposite advice.
Triglycerides move fastest
They fall within weeks of cutting sugar and alcohol, which makes them a useful marker of whether a change is actually being made.
Read as a set
A high total driven by high HDL is a different situation from the same total driven by high LDL. The breakdown is the point.
What is measured
The overall figure. Too crude to act on alone, since it includes both LDL and HDL.
The fraction that deposits into artery walls. The main treatment target.
Carries cholesterol away from arteries. Here, higher is generally better.
A separate fat that rises with sugar, alcohol and weight, and falls quickly when those change.
How to prepare
- Fasting
- 9–12 hours
- Best time
- Morning, so the fast falls overnight
- Avoid before
- Alcohol for 24 hours
- Worth knowing
- Water is fine and you should take your usual medicines. Fasting matters mainly for triglycerides; cholesterol itself changes little.
What can move the result
A result outside the usual range does not on its own mean something is wrong. These are the everyday explanations a doctor considers first.

Frequently asked questions
Cholesterol travels in particles. LDL deposits it into artery walls; HDL carries it away. Triglycerides are a separate fat that rises sharply with sugar, alcohol and weight. What a given set of numbers means for your cardiovascular risk — and whether it warrants treatment — follows the joint ACC/AHA dyslipidaemia guideline rather than a single cut-off. LDL is the treatment target: It narrows arteries silently over decades and causes no symptoms until a heart attack or stroke. That is the entire reason it is screened rather than waited for.
Fasting: 9–12 hours. Best time: Morning, so the fast falls overnight. Avoid beforehand: Alcohol for 24 hours. Water is fine and you should take your usual medicines. Fasting matters mainly for triglycerides; cholesterol itself changes little.
Commonly: diet, particularly sugar and refined carbohydrate; weight and how much you move; alcohol in the day or two before; familial high cholesterol, which is inherited rather than dietary; an underactive thyroid, which raises cholesterol until treated. A single result is not a diagnosis. Values are read against the laboratory's own reference range and alongside your history, your symptoms and the rest of the panel — which is why every package includes a doctor to go through them with you.
