Haemoglobin K‐Woolwich as Cause of Falsely Elevated HbA<sub>1</sub>

Glycated haemoglobin (HbA1c) is routinely used to assess the degree of glycaemic control in diabetic patients. We report a case of a 73 year old diabetic woman who had an elevated HbA1c of 13.4%. She was on maximum oral hypoglycaemic agents and was commenced on insulin. However, her HbA1c continued to remain high at 20.4%. Subsequent tests revealed that she had a haemoglobin variant, Haemoglobin Osu-Christiansborg, causing the falsely high glycated haemoglobin.

Haemoglobin K‐Woolwich as Cause of Falsely Elevated HbA₁

Abstract: Falsely elevated levels for haemoglobin A1 can be found with the haemoglobinopathies. A case is reported where falsely high levels for haemoglobin A1 were caused by the asymptomatic presence of haemoglobin K-Woolwich.
