Cholesterol blood test

In most cases, yes. Doctors typically recommend fasting for 10 to 12 hours before your blood draw to get the most accurate reading of your triglyceride and LDL cholesterol levels. This means no food or drinks other than water. Your doctor will confirm the fasting requirements during your consultation.

For most Australian adults, a cholesterol test is recommended every five years from the age of 45. If you have a family history of high cholesterol or heart disease, or if you have other risk factors such as diabetes or high blood pressure, your doctor may recommend more frequent testing. Aboriginal and Torres Strait Islander peoples should start screening from age 35.

Once your doctor issues a pathology request through InstantScripts, you can visit any pathology collection centre in Australia. Major providers like Laverty, QML, and Australian Clinical Labs have centres in most suburbs and regional towns. No separate appointment is usually needed for a walk-in blood draw.

Your results will show levels for total cholesterol, LDL, HDL, and triglycerides. Generally, higher LDL and triglyceride levels increase cardiovascular risk, while higher HDL levels are considered protective. Your doctor can explain your specific results and whether any changes to diet, exercise, or medication may help.

Cholesterol testing is recommended for all adults from age 45 as part of a routine cardiovascular risk assessment. You may need earlier or more frequent cholesterol blood tests if you smoke, have a family history of heart disease, are overweight, or have diabetes or kidney disease. Your doctor can advise on the right screening schedule for your situation.
