Cholesterol
Cholesterol is a type of lipid involved in normal body functions. Blood lipid results are commonly considered together with other health information and individual risk factors.

What is cholesterol?
Cholesterol is a waxy substance that the body needs for important functions, including making certain hormones and helping build cells. The body produces cholesterol naturally, and it is also present in some foods. Blood tests can measure different types of cholesterol and related fats, which together provide information about cardiovascular health.
A cholesterol result should be considered as part of a person's wider health picture. Age, family history, blood pressure, smoking, diabetes and other factors can affect cardiovascular risk, so a single laboratory value does not tell the entire story.
Understanding cholesterol results
Common lipid measurements include LDL cholesterol, HDL cholesterol and triglycerides. These measurements describe different aspects of blood lipids and may be reported together as a lipid panel. The meaning of a result depends on the person's circumstances and the reference ranges or targets used by their healthcare professional.
When recording results, keep the date of the test and the laboratory report alongside the numbers. This makes it easier to compare results over time without relying on memory.
Tracking cholesterol over time
Repeated results can provide more useful context than one isolated measurement. Keep a dated record of laboratory results, relevant medicines and major changes in health or lifestyle. A record can also note when a healthcare professional discussed the result and what follow-up was recommended.
Do not change or stop prescribed cholesterol medicines based only on an online explanation or one test result. Medication decisions should be discussed with the prescribing healthcare professional.
When to discuss results with a professional
Discuss cholesterol results with a qualified healthcare professional, particularly when results are unexpectedly high or low, when several cardiovascular risk factors are present, or when you are unsure what a laboratory report means. Professional interpretation can put the numbers into the context of the person's overall health.
