Antistreptolysin O (ASO)
Antistreptolysin O (ASO) is a clinical biomarker on the Infection panel, reported in IU/mL. Standard reference range: 0–200 IU/mL. Functional (optimal) range used by integrative practitioners: 0–200 IU/mL.
What is Antistreptolysin O (ASO)?
ASO antibodies indicate prior or recent Group A Streptococcal infection; elevated titers support post-streptococcal sequelae such as rheumatic fever or PANDAS.
Reference ranges
| Range type | Value (IU/mL) | Source |
|---|---|---|
| Standard (lab) | 0–200 | Typical Quest / LabCorp adult reference |
| Functional (optimal) | 0–200 | Integrative / functional medicine consensus |
How SomaVue interprets Antistreptolysin O (ASO)
SomaVue maps every result for Antistreptolysin O (ASO) against four clinical lenses — nutrient cofactors, toxin exposure, infection drivers, and circadian/hormonal context — and connects each interpretation to specific peer-reviewed citations. Pre-mapped clinical reasoning and cross-marker pattern detection are available inside the practitioner workspace.
