Laboratory Guide 2022

Lab guide 2021 cover

Every year we review requesting patterns, frequency of use, 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 as relevant as possible. The Laboratory Guide 2022 has been updated; there are about 1500 tests listed in sections, by speciality, and through the A – Z test index in the last section of the guide. For clinical 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 tests.

For those who are taking samples, the inside back cover of the laboratory guide gives details of the sample types, with coloured dots for the identity of the BD vacutainer tubes  (A B C F G H K). Throughout the guide the number of tubes needed is shown by the given number of dots.
