Apparent Proteinuria as a Consequence of Sodium Bicarbonate Ingestion
1 Department of Pediatrics, The Johns Hopkins University, School of Medicine, Baltimore, Maryland
An infant who is brought to an emergency department with vague symptoms poses a difficult problem for the pediatrician. The presence of specific findings on laboratory screening tests often helps to narrow the differential diagnosis, enabling appropriate treatment. Unexpected laboratory results, however, may lead the physician astray in making the correct diagnosis. It is important to interpret laboratory results within the context of the entire clinical picture and to keep in mind the limitations of certain of these tests. We report a case of apparent proteinuria in a 7-week-old infant caused by the addition of baking soda to his formula, and point out that careful history-taking may help to avoid an extensive diagnostic workup.
