Summary of SAGE IVD recommendation

General in vitro diagnostics tests are the general core and routine laboratory tests for clinical chemistry, haematology, blood transfusion, clinical microbiology (virology, bacteriology, parasitology, and mycology) and other tests relevant to clinical pathology and anatomical pathology. These tests were selected based on the scientific validity of an analyte, i.e. the association between an analyte and a clinical condition or physiological state, and clinical utility. Many of these tests are required for effective management of patients and have already been described in WHO publications.
