How to prepare
No fasting is required. You can eat and drink normally before your blood draw.
This is a standard blood draw test. A small sample of blood is taken from a vein in your arm at the pathology centre.
If you smoke, note this on any forms provided. Smoking status is relevant context for interpreting a cadmium result.
After the test
Share your results with your doctor or a healthcare practitioner. They can assess whether your cadmium level is clinically significant in the context of your smoking history, occupational exposure, and any symptoms.
If your level is elevated, your practitioner may consider the likely source and recommend ways to reduce ongoing exposure. For smokers, reducing or stopping smoking is the most effective way to lower cadmium intake. For occupational exposure, your practitioner may liaise with your workplace health programme.
If your result is within the reference range, it provides a useful baseline for ongoing monitoring, particularly if you are a smoker or work in an at-risk industry.
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
Your result shows your blood cadmium concentration measured against the reference range for the general population.
A result within the reference range is consistent with typical background exposure. Smokers often have cadmium levels several times higher than non-smokers due to the cadmium content of tobacco smoke, so reference ranges are sometimes presented separately for smokers and non-smokers.
Elevated results indicate higher cadmium than expected and may reflect active smoking, occupational exposure, or dietary or environmental intake. Because cadmium accumulates in the kidneys over years, a blood test result showing current exposure levels does not fully reflect total body burden.
Share your results with a qualified healthcare practitioner who can review them alongside your smoking history, occupational history, and any symptoms you are experiencing.
