Abstract

This is an informative article which can help research providers to arrange and conduct studies dedicated to the assessment of metformin serum concentrations. If there is a problem with coordination of sample preparation and it is necessary to measure metformin concentration, two hours gap between blood drain and centrifugation has no impact on the results.

Keywords: Centrifugation; Metformin serum concentration; Sample Handling Time.
