Q

What are two common causes of platelet abnormalities?

A
  • Bleeding disorders

- Hypercoagulable states

17
Q

What two lab values typically “follow” MCV?

A
  • MCH

- MCHC

18
Q

What will be seen in leukocytosis with a “left shift”?

A

BAND neutrophils (often due to bacterial infection)

19
Q

What lab value is often correlates with neutrophil abnormalities?

A

WBC (leukocytosis or leukopenia - so if one is low, the other is likely low too)

20
Q

Are the “-phils” or “-cytes” granulocytes?

A

“-phils” = granulocytes

“-cytes” = nongranulocytes

21
Q
