Creating a list of CTC schemes

CT criteria are particular to a CTC scheme and to a clinical test, regardless of the laboratory in which that test is performed. However, as they are usually defined in relation to the normal ranges for that test, they are indirectly linked to a particular laboratory. Only one CTC scheme may be used per study.

To create, edit or delete a CTC scheme, you need the 'Maintain CTC schemes' permission

Select Parameters > Normal Ranges and CTC. The Normal Ranges and CTC window is displayed.
Select the CTC Schemes tab.
Click Create. Fields that are filled with yellow are mandatory and need to have valid data entered before the screen can be saved.
Enter a unique code and a description for the CTC scheme. This must begin with a letter and may have up to 15 alphanumeric characters. Spaces are not allowed but you can use the underscore character instead.
Click Save to save the new scheme, or Cancel to abort the creation.

Select Parameters > Normal Ranges and CTC. The Normal Ranges and CTC window is displayed.
