Which laboratory report finding would the nurse expect for a child with acute glomerulonephritis?

In the case of a child with acute glomerulonephritis, an increased antistreptolysin O (ASO) titer is expected because this condition is often post-infectious, particularly following a streptococcal infection. The ASO titer is a measure of antibodies produced against streptolysin O, a toxin produced by certain strains of Streptococcus bacteria. An elevated level indicates that the body is responding to a recent infection, which can trigger the glomerulonephritis process. This autoimmune response results in inflammation and damage to the glomeruli in the kidneys, leading to the symptoms characteristic of the disease.

Other laboratory findings that may accompany acute glomerulonephritis include hematuria and proteinuria, along with signs of immune activity, which further implicate the need to assess ASO titers in conjunction with ongoing evaluation and management of the condition.
