Childhood Adenotonsillectomy Trial

4.3 Processing

4.3.1 Overview

Processing should be initiated as soon as possible (< 30 minutes) following venipuncture. The red-topped serum tubes must stand at room temperature for 40 minutes before centrifugation. If centrifugation of the other tubes is not immediate, the EDTA tube should remain on ice. Personal protective equipment (non-permeable lab coats, double-gloves with at least one latex pair, splatter shields) is required for processing.
