Important Information About Mobile Collection Services
Our mobile collection service involves a trained collection officer travelling to a location specified by you to perform the required sample collection.

Please note that this is not a mobile unit or vehicle you can visit. Instead, the service is designed to provide on-site convenience, allowing you to arrange testing at your home, workplace, or another designated location.
