Chronic is often asymptomatic until very severe



What does an MCV value tell you? What is a normal value? What would a low and high value be
called?

Ξ -:- the size of the RBC



normal: 80-100

>100: macrocytic (large RBC)

<80: microcyctic (small RBC)



What does an MCHC value tell you? What is a normal value? What would a low and high value be
called?

Ξ -:- the "color" of the RBC or how saturated it is with HGB

Normal: 32-37

high value not a thing

<32: hypochromic (lacking HGB)



What does an RDW value tell you? What is a normal value? What would a low and high value be
called?

Ξ -:- essentially how far apart the RBCs are from each other - the further apart, the

less RBCs, otherwise they would be closer just based on the sheer volume
