If the cofactor is tested composite by PRP test, the cofactor is certainly composite. If you refer to this page, then yes, it may be kind of confusing to see PRP cofactor written there, but that's really only a title. If it would be PRP, for real, it would have had written "PRP_PRP_PRP_PRP_" in place of residue.
