Duffy blood group test.
All Greenfields tests are carried out in our haematology lab and the results are posted to you.
To find your Duffy subgroup only, choose this basic Duffy Blood Group Test. This will tell you if you are Fya+ or Fya- and Fyb+ or Fyb-. It will not tell you your ABO blood group or secretor status.
The kit will provide instructions to collect a few drops of blood from your finger and return it to the laboratory. We will test your Duffy blood group and you can download the results from our online helpdesk.
