Diabetes Test May Fail Children
(BlackDoctor.org) – According to the American Diabetes Association, almost 24 million people, or about 8% of the population of the United States, have diabetes, including about one in every 400-600 children and adolescents.
A new study has important implications for clinical practice in the testing of African American children for diabetes. HbA1c is the main test used to monitor diabetes and guide treatment decisions and it has been found that results can be deceptive in African American children — misleading their doctors into believing that glucose levels are higher than they really are. Test scores were higher than those for white children, even when average blood glucose levels were similar, and this suggests that results might need interpreting differently for African-Americans.
While ordinary blood glucose tests would give the correct results for black children, the new research suggests that an HbA1c test would be misleadingly high, perhaps leading doctors to think that treatment isn’t working as well as it should. This could lead to more aggressive treatment that reduces someone’s blood sugar too much, and leads to episodes of hypoglycaemia.
According to Dr Stuart Chalew, a pediatrician at the New Orleans School of Medicine, “If doctors don’t take both HbA1c and self-monitored blood sugar levels into account, they are likely to unintentionally provoke increased episodes of life-threatening episodes in African-American patients”.
Black people tend to have a higher risk of getting complications from diabetes, which could partly be explained by their HbA1c levels responding differently to their blood sugar. In the long term, this finding may lead to new treatments to prevent diabetes complications.
