Laboratory testing via TDL

Over 1,300 blood tests, one search box.

Tower Bridge Hospital runs its pathology through TDL (The Doctors Laboratory), one of the UK’s largest independent labs. Search any test or profile by name or code — including TDL’s package bloods like DL2 and the Well Person profiles — to see what it includes, the sample needed and the turnaround time.

Browse by department

Every test grouped the way the laboratory groups it. Pick a department to narrow the list.

Sample requirement key

Codes in the sample column follow TDL’s standard tube abbreviations. Your clinician confirms the exact requirement at the time of testing.

This directory lists tests available to order through TDL and is provided for information only. It is not medical advice, and inclusion of a test does not imply it is clinically appropriate for you. Sample requirements and turnaround times are indicative and set by the laboratory; turnaround is counted from the lab receiving the sample. Data compiled from the TDL Laboratory Guide 2025.
