Hi gang!

Why in folate deficiency (megaloblastic anemia) do you have HIGH MCH, but LOW MCHC? I guess the low MCHC is the one I'd like an explanation for the most.

Thank you smiling face

MCH= Hb/RBC count
MCHC=Hb/Hct (Hct= RBC count*MCV)=MCH/MCV

in megaloblastic anemia MCV is high so, MCHC is low

Isn't MCHC normal in folate deficiency (Harmening: Hematology)?

Thanks Mash! Hi Sakaki--this q was straight from Qbank..which means it could be wrong of coure!

Anyone know?
Thanks again Mash-ster!

  #5

as mash put it correctly : MCHC=MCH/MCV.
both MCH and MCV inc.(leading to HyperChromic+Macrocytic cells respectively) but MCHC doesnt change much (both denominator and numerator inc.!! smiling face )
mash i think it is the Fe-def in which MCHC also dec. am i wrong ?

I'm positive that MCHC is used to assess whether cells are hypochromic, normochromic (or hyperchromic - though this term really isn't proper, from what I remember).
