Choosing a test
A comprehensive panel measures several related markers, while a single-marker test addresses a more focused question. A larger panel is not automatically the right choice. Discuss your symptoms, previous results and referral with a qualified clinician before selecting tests. Results should not be interpreted in isolation.
Before sample collection
Confirm the required tube, sample volume, any fasting instructions and the collection deadline for your chosen test. Tell the collection team about medication and recent treatment. Do not stop prescribed medication unless your clinician advises it. Home collection depends on the sample’s handling and transport requirements.
