Investigation Details
For blood specimens, the colour of the text within the 'Container' column indicates the required specimen lid colour.
If unsure, click the text within the column for an image (See 'Sample Containers' section for paediatric versions).
Please note that the volumes quoted relate to individual tests.
If multiple tests are ordered, an appropriate increase in sample volume may be required.
Multiple tests for the same specimen type will normally only require a single specimen.
All requests made electronically via the ICE system will automatically include on the request form the type and number of specimens required.
