E



  #9

FOR E WON,T U REQUIRE COOMBS TEST OR ONLY BLOOD SMEAR WILL SUFFICE? WHY IS F WRONG?


  #10

E .. but yasmeen is right about Ret Count on F confused


  #11

it says in blood smear!!! you can not see Ig in blood smear.

So I say F



  #12

this is a case of post transfusion hemolysis as evidenced by the bilirubinemia and slightly high LDH. i think it is C cos erythrocyt ghosts are seen after hemolysis.

i dont think it can be F because nucleated erythrocytes are rarely seen ( they are not reticulocytes) they are seen following acute severe anemia eg from severe hemolysis ( bilirubin and LDH will be high), or metastatic cancer to bone???? please correct me.

i got a good site with a nice simple discussion i cannot seem able to post the link.
