Acute poststreptococcal glomerulonephritis:
Diagnosis
(Professional Guide to Diseases (Eighth Edition))
Diagnosis requires a detailed patient history and assessment of clinical symptoms and laboratory tests.
Urinalysis typically reveals proteinuria and hematuria. RBCs, white blood cells, and mixed cell casts are common in urinary sediment. Elevated serum creatinine levels and low creatinine clearance accompany impaired glomerular filtration. Elevated antistreptolysin-O titers (in 80% of patients), elevated streptozyme and anti-DNase B titers, and low serum complement levels verify recent streptococcal infection. A throat culture may also show group A beta-hemolytic streptococcus. Renal ultrasound may show a normal or slightly enlarged kidney. A renal biopsy may confirm the diagnosis or assess renal tissue status.

❑ Blood tests show elevated serum creatinine levels, low creatinine clearance, and impaired glomerular filtration.
❑ Elevated antistreptolysin-O titers (in 80% of patients), elevated streptozyme and anti-DNase B titers, and low serum complement levels verify recent streptococcal infection.
