Test Code LAB219 Strep Screen (Anti-Streptolycin O)

Additional Codes

CPT Code: 86060

Methodology

Includes qualitative antistreptolysin O (ASO) titer with a semiquantitative ASO titer performed on all sera which are positive with the screening test.

Performing Laboratory

TidalHealth Peninsula Regional - Serology

Specimen Requirements

Draw blood in a gold-top serum gel tube. (Hemolyzed specimen is not acceptable.) Spin down and send 2 mL of serum.

Reference Values

Negative

Note: 200 IU/mL is accepted internationally as upper limit of “normal range” since this value was seldom exceeded in persons without clinical symptoms among whom streptococcal infections were suspected. Normal values in preschool age children lie mostly below 100 IU/mL. ASO titers increase with age in children, reaching a peak among school aged children, then falling thereafter. A 2-fold or greater rise in ASO titer is considered significant in all age groups.
