About Paul Charest Expertise Any questions that have to do with hematology. Explaining laboratory tests including :coagulation (PT/aPTT), CBC, differential, ESR, and flow cytometry (leukemia/lymphoma)also including the theory behind them. Hemoglobinopathies, leukemia, lymphoma, hemostasis, hematopoiesis, and cellular morphology are a few of the topics that I teach and practice.
I also have experience with immunohematology, otherwise known as blood banking. Feel free to ask about blood types, blood groups, the type and crossmatch, transfusions, antibody identification, DAT, elutions as well as absorptions
I have also worked in a parasitology lab, as well as taught the subject as well. So feel free to ask about helminths (cestodes, trematodes, and nematodes), protozoan parasites, sporozoan etc.
Lastly, I teach a course in clinical mycology where we grow and identify yeasts and moulds.
Experience I have worked in a hematology lab, flow-cytometry lab, blood bank, and microbiology lab. I am also an instructor at Northeastern University part-time

Question I was wondering if there are any visible differences between blood types besides the Rh factor?
Answer Hello Adam,
There are many different proteins that may or may not be expressed on the surface of red cells. Aside from ABO blood types and "Rh factor" there are many others as well. The "Rh factor" that you are talking about is referred to as the D antigen. There is a Rh family of antigens in addition to the D antigen. To name a few from the Rh family: C,c,E,e,f,cW. There are also other families as well including :
Kell group---K, k
Duffy group----FyA, FyB
M, N
S, s
Lewis---LeA, LeB
JkA, JkB
