Elevated antistreptolysin O (ASO) titers are primarily associated with poststreptococcal glomerulonephritis, which is a condition that can occur following an infection with certain strains of Streptococcus bacteria, particularly Group A streptococcus. After a person recovers from a pharyngeal or skin infection caused by these bacteria, the body produces antibodies to streptolysin O, a hemolysin produced by the organism. These elevated ASO titers serve as an indicator of recent streptococcal infection and are often used in the diagnosis of poststreptococcal glomerulonephritis.

This renal condition typically presents with symptoms of hematuria, proteinuria, edema, and hypertension, often occurring a few weeks after the initial streptococcal infection. The relationship between elevated ASO titers and poststreptococcal glomerulonephritis is well-established and supports a link between the streptococcal infection and the subsequent kidney inflammation.

The other conditions listed do not directly correlate with elevated ASO titers. IgA nephropathy is characterized by the deposition of IgA antibodies in the kidneys and does not involve strept
