This glomerulus is hypercellular and capillary loops are poorly defined. This is a type of proliferative glomerulonephritis known as post-infectious glomerulonephritis. This case followed a group A beta hemolytic streptococcal infection of the pharynx 3 weeks earlier, and thus it could be termed 'post-streptococcal gomerulonephritis'.

Question: What 3 serologic tests have high sensitivity for post-streptococcal GN?

AnswerThe anti-streptolysin O (ASO), anti-hyaluronidase, and anti-DNase B tests together are highly sensitive to detect an immunologic response to prior group A streptococcal infection.
