Buy Duffy Blood Group Tests

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 the basic Duffy Blood Group Test (£44). This will tell you if you are Fya+ or Fya- and Fyb+ or Fyb-.

To add the ABO blood group (with subgroups of A) and Rh (D) blood group test choose the Duffy and ABO Test (£73).

To add the secretor status test, choose the Duffy and Lewis Test (£85.00). This will not test for your ABO blood group.

To find your Duffy and MN subgroup choose the Duffy and MN Subgroups Test (£78.00). This will not test for your ABO blood group.

To add the ABO test and secretor status test (by Lewis group) with MN subgroup, choose the Full Blood Grouping and Subgrouping Test with Duffy Group (£149). This will test for ABO, A1/A2, Rhesus (D), Lewis blood group (for secretor status), MN and Duffy subgroups.

The Lewis test is genetically linked to ABO saliva secretor status, but will not give results in about 5% of people. For results of Lewis Negative you may want to buy a Saliva Secretor Test.
