New Correction Factor for AST Coming in Core Labs

The Core laboratories in the Department of Pathology and Laboratory Medicine will be implementing a new correction factor for aspartate aminotransferase (AST) run on Ortho Vitros analyzers in April.

The move, which impacts medical staff in the Emergency Department and the Samuel Oschin Comprehensive Cancer Institute, is designed to produce results that better match the primary method used in the main laboratory that are run on Roche P modules.

AST on Ortho Vitros runs about 15 percent higher than AST on Roche Modular. While the difference may often not be clinically significant, especially for more elevated values, the goal is to provide results that are as consistent as possible across all three labs.

As such, a correction factor to better match Vitros to Roche values will begin Monday, April 10. The graph below shows that the correlation between both AST methods is strong despite this small, but persistent bias.
