title: A new alpha chain variant, Hb Turriff [alpha 99(G6)Lys----Glu]: the interference of abnormal hemoglobins in Hb A1c determination.
abstract: Hb Turriff is a new hemoglobin variant which we have identified in a diabetic individual. During the determination of Hb A1c by high performance liquid chromatography, an inappropriately elevated result was found to be due to the abnormal hemoglobin chromatographing with the Hb A1c fraction. This new hemoglobin variant, Hb Turriff [alpha 99(G6)Lys----Glu], is not associated with any hematological disturbance, and family investigations indicate that it has arisen as a de novo mutation.
