• In Spectrum Health Epic, labels for Blue Citrate tubes for coagulation testing will now state “2.7mL BLUE” instead of just “BLUE”. This will help clarify proper collection volume. The number of labels that print, should be the number of 2.7mL tubes (calculated in Epic) that need to be drawn based on the number of tests ordered. It is important to note – if a 1.8mL sodium citrate tube is used instead of a 2.7 mL sodium citrate tube, a potential QNS (Quantity Not Sufficient) may result, depending on the tests ordered and results obtained.
