Familial pseudohyperkalaemia, Cardiff type – http://id.who.int/icd/entity/975216558

This is a dominant red cell trait characterised by increased serum potassium in whole blood stored at or below room temperature, without additional haematological abnormalities. It appears to be due to mutations in Langereis blood group antigen which encodes an erythrocyte membrane porphyrin transporter. This diagnosis is the Cardiff type.
