This test analyses a blood/urine sample to detect specific markers relevant to your symptoms and health status. Our doctor explains all results in the context of your clinical picture.
Reference ranges are age, sex, and clinical-context dependent. Our doctors interpret every result in context — not just against a printed range.
A result that requires further action triggers a management plan on the same visit — medication, further tests, or referral — so you leave with clarity, not just a piece of paper.
