What Do I Do When Samples Are Sent to the Lab Within Minutes on the Same Patient and the Results Do Not Match?

A 74-year-old patient who was in the critical care unit was having daily hematology blood work performed. The first sample was sent to the laboratory at 2:23 p.m. Hemoglobin and hematocrit were the only analyses requested. The results were verified without delta flags. The second sample was sent 20 minutes later with a request for hemoglobin and hematocrit. Both samples were cycled through the automated instrument and a full CBC was obtained. Only the hemoglobin and hematocrit were reported. The results:

First Sample at 2:23 p.m.

Second Sample at 2:43 p.m.
