Pathology is the branch of medicine covering laboratory testing of blood, urine, swabs and tissue samples. It underpins most diagnoses, from routine cholesterol and iron checks to hormone panels, infection testing and cancer screening.
In Australia, a doctor issues a pathology request form and the patient attends any collection centre of that provider network. Many common tests attract Medicare rebates when clinically indicated. Telehealth fits neatly: requests are emailed, collection happens locally, and results are reviewed in a follow up consultation.
