Question 8

Purpose of MCV

Answer 8

Indicates the size of RBC’s therefore determines the volume of RBC’s

Question 9

Purpose of MCH

Answer 9

Shows the average hemoglobin concentration of RBC’s. Is always interpreted with MCV (smaller RBC’s have less Hgb)

Question 10

What is MCHC

Answer 10

The average Hgb in a deciliter of RBC’s

Question 11

Purpose of MCHC

Answer 11

To determine if the cell is Normochromic, Hyperchromic or Hypochromic

Question 12

Purpose of the RDW

Answer 12

Determine variations in RBC size (anisocytosis) determines age of RBC’s. is a SD of the MCV (young are larger than older)
