Understanding Your Pet’s Bloodwork

 

“CBC, chem seven, stat!”  This may sound familiar If you watch such popular television dramas such as ER, Chicago Hope, and Emergency Vets.  But do you know what the terms mean?  Blood tests help doctors determine causes of Illness accurately, safely, and quickly and let us monitor the progress of medical treatments.  To help you understand your pet’s test results, this guide explains common tests.  A checkmark in any box indicates a significant abnormal finding on your pet’s blood work.  If you have questions, ask any staff member.  We want you to understand our recommendations and be a partner in your pet’s care.

Complete blood count (CBC)

This test is essential for pets with fevers, vomiting, diarrhea, weakness, pale gums, or loss of appetite. If your pet needs surgery, a CBC can detect bleeding disorders or other unseen abnormalities.
