A child with suspected sickle cell disease is scheduled for a hemoglobin electrophoresis. When reviewing the child's history, what would the nurse identify as potentially interfering with the accuracy of the results?
A) Use of iron supplementation
B) Blood transfusion 1 month ago
C) Lack of fasting for 12 hours
D) History of recent infection
Ans: B
Blood transfusion within the previous 12 weeks may alter the results of the hemoglobin electrophoresis. Iron supplements can increase serum ferritin levels. Children should fast for 12 hours before having a specimen obtained for iron levels. A history of infection might interfere with the white blood cell count results, not hemoglobin electrophoresis.
