ASO Antibody – Anti-streptolysin is an antibody that attacks the antigen known as ‘STREPTOLYSIN-O’ which is produced by Bacteria A Streptococcus but due to similarity of antigenicity the immune response is also triggered against self-antigens such as Myocytes. This test evaluates the ASO antibody in the blood to examine if the patient was previously exposed to Strep Infections, later leading to complications such as Rheumatic Fever or Glomerulonephritis (Kidney Disorder).

Why the Anti-Streptolysin Antibody test?


Anti-Streptolysin Antibody Test is a blood test that checks for toxin known as streptolysin-O during Group-A Streptococcus (GAS) bacterial infection. Symptoms include strep throat, Scarlet fever, chest pain, fatigue, shortness of breath, palpitation, joint pain, small painless nodules under the skin, Sydenham’s chorea (rapid and jerky moments), edema (fluid accumulation) which can lead to hypertension, dark urine, reduced urine output, bloody urine, etc. Complications include post-streptococcal complications such as bacterial endocarditis, kidney disease due to glomerulonephritis, and rheumatic fever that causes damage to the heart valves.  Other confirmatory tests for Streptococcal infection apart from ASO antibody tests include anti-DNase B (confirmatory test).
