Test Advice

 

The Test Advice page is designed as an aid to assist test selection and is not intended to override clinical judgment in individual cases.

It is a support document that underpins Sullivan Nicolaides Pathology's eOrdering application which is available in Best Practice and Medical Director. For more information about SNP eOrdering, please contact your Medical Liaison Manager on 1300 SNPATH (1300 767 284).

Every effort has been made to ensure the Test Advice page is free from error or omission.
