• Hematocrit (Hct): How much of your blood is red blood cells.
• Mean Corpuscular Volume (MCV): The size of your red blood cells.

Bad CBC results can mean things like anemia or an infection. It's good to understand blood test results for the CBC. It is key!

The BMP tells you about your kidneys, electrolytes, blood sugar, and calcium. Bad results can mean dehydration or diabetes. Learning to understand blood test results from the BMP can point to problems.
