jschlosser Posted July 24, 2011 Share Posted July 24, 2011 Would someone please explain the f antigen and antibody for me. I can't seem to get it straight and if I do I don't retain it! Thanks in advance. Link to comment Share on other sites More sharing options...
jschlosser Posted July 25, 2011 Author Share Posted July 25, 2011 Or where I can find information. I did a search of this site and didn't find all that much, which confuses me because I think it's talked about alot. I also searched the internet and what I found didn't explain it well. Thanks Link to comment Share on other sites More sharing options...
David Saikin Posted July 25, 2011 Share Posted July 25, 2011 You can look at the "antigens" area of this site - under Rh. f ag occurs when ce are together ®. It is a compound ag dervied from the configuration of c and e ags together. Link to comment Share on other sites More sharing options...
jschlosser Posted July 25, 2011 Author Share Posted July 25, 2011 If a DCe/DcE patient receives Rh negative blood (usually dce/dce)then they may develop anti-f ?The Rh genotypes DCe/DCe and DCe/DcE can make anti-f whereas DCe/dce, DcE/dce and dce/dce can cause the anti-f to be made if transfused into the first two genotypes? What about auto anti-f. Is there a tendency of any paticular genotype to make it more often? It occurs often with anti-c? Link to comment Share on other sites More sharing options...
yolis76 Posted September 21, 2011 Share Posted September 21, 2011 If a DCe/DcE patient receives Rh negative blood (usually dce/dce)then they may develop anti-f ? --> I would say yes because the recipient does not have the 'f' antigen (you need to remember that the ce antigens must be inherited from the same haplotype ie the same parent); the donor does express the 'f'antigen, therefore the recipient may form Anti-f.The Rh genotypes DCe/DCe and DCe/DcE can make anti-f whereas DCe/dce, DcE/dce and dce/dce can cause the anti-f to be made if transfused into the first two genotypes? --> yes, see above.What about auto anti-f. Is there a tendency of any paticular genotype to make it more often? It occurs often with anti-c? --> not sure but there's just about auto-anti-anytying... Marion Reed's book might give you a better idea about the frequency of this occurring. Link to comment Share on other sites More sharing options...
Malcolm Needs ☆ Posted September 22, 2011 Share Posted September 22, 2011 Remeber also, that an apparent R1R2 (DCe/Dce) may actually be an Rzr (DCE/dce) or other rare genotypes (such as dCE/Dce or DCE/Dce), all of which can stimulate anti-f (or react with it) and so we always advise givine R1R1 or R2R2 blood, depending upon the recipient's Rh type - just in case!
