How to prepare
Fasting for 10–12 hours before your blood draw is recommended. Water is fine to drink. Take medications as normal unless your practitioner has advised otherwise. Avoid strenuous exercise the day before.
After the test
Share your results with your GP or cardiologist, particularly if you have a personal or family history of cardiovascular disease. An elevated ApoB or unfavourable ratio often prompts a broader cardiovascular risk assessment — including blood pressure, glucose, and full lipid studies — rather than action on a single number alone.
Your test results will be available in your private dashboard. If there are any urgent issues, we'll let you know so you can follow up with your health professional.
Understanding results
ApoA1 reflects the capacity of your HDL system to remove cholesterol from tissues. Higher is generally better. Low ApoA1 can indicate reduced cardioprotective function.
ApoB reflects the total number of atherogenic lipoprotein particles in circulation. Lower is generally better. Elevated ApoB suggests more particles available to deposit in artery walls, even if LDL-C appears normal.
ApoB:ApoA1 ratio is calculated from both values and is the figure most practitioners focus on. A higher ratio points toward greater cardiovascular risk.
Reference ranges vary slightly between laboratories. Your result will come with the reference range used and should be reviewed in the context of your full cardiovascular history.
