Abstract

Group A streptococcus can cause several diseases that range from mild pharyngitis and impetigo to severe post-streptococcal sequelae. Group A streptococcus produces super-antigens such as streptolysin O (SLO). Group A streptococcus can activate the immune system to produce antibodies specific to SLO. Therefore, clinical laboratories confirm previous and existing group A streptococcus infections by detecting SLO-specific antibodies in patient’s serum. Here, the principle, applications, reagents, steps, and results interpretation process of the most commonly used test in clinical laboratories to detect SLO antibodies are explored.
