## Overview

[edit | edit source]

Antistreptococcal antibodies are antibodies against a series of streptococcal exoantigens. They play a critical role in acute infections of the body surfaces, and certain organs.

Antistreptolysin O titre (AS(L)O titre or AS(L)OT) - titre of (serum) antistreptolysin O antibodies; a blood test used to assist in the diagnosis of a streptococcal infection or indicate a past exposure to streptococci. The ASOT helps direct the antimicrobial treatment and is used to assist in the diagnosis of scarlet fever, rheumatic fever and post infectious glomerulonephritis. The false negatives rate is 20-30%.[1] If a false negative is suspected then an anti-DNase B titre should be sought. False positives can result from liver disease and tuberculosis.[1]

## Reference Range

[edit | edit source]

ASO/ASL | Up to 200 IU (adults) [1] but normal ranges vary from laboratory to laboratory and by age.[2]

|

| Up to 150 IU (children)
ADNase | Up to 200 IU
