Laboratory Guide 2021

Lab guide 2021 cover

At the end of every normal year we review requesting patterns, frequency of use, new best practice, new methods, and include new and relevant assays into the test menu. We also try to incorporate the changes that have originated from feedback received over the past year. This helps us to keep profiles and test menus as up to date and relevant as possible. The Laboratory Guide 2021 has been updated; there are about 1500 test listed through the departments, by speciality, and through the A – Z test index in the last section of the guide. For advice or information about any of the tests that are listed – and particularly if you cannot find the test you are looking for – please contact the laboratory on 020 7307 7373. If you need information and advice about Genetic Tests please call 020 7307 7409.

The symbol NEW shows new entries with reference to new tests,
changes and updates effective from 1st January 2021.

The Tabs will help you navigate to the various disciplines, and for sample takers, the inside back cover of the laboratory guide gives details of sample requirements, with coloured dots to match the number of tubes, and colour of the BD vacutainer top  (A B C F G H K).
