* These haemoglobin variants are sometimes labelled HbA2 and sometimes unknown depending on the instrument and slight variations in retention times. Even when the variant does not precisely co-elute with HbA2, it may still interfere with the HbA2 measurement and so a different method of measuring the HbA2 should be used in this situation.
