** Using the Mnemonic selection automatically applies the following comment to the patient’s record: “Testing performed on hemolyzed specimen. Moderate hemolysis (as low as 0.9%) can influence the reliability of coagulation testing, causing falsely elevated PT and D-Dimer results and falsely low PTT and Fibrinogen results. Sample recollection is recommended.” / NOTE: Hemolyzed TT samples are unacceptable and must be redrawn.
