Test Methodology

Semi-Quant Immunodiffusion.


Patients with skeletal infections may elicit weak, or no antibody response to staphylococcal ribitol teichoic acid.

Occasional weak titers (Undiluted, 1:2) may be expected in uninfected individuals.

A negative teichoic acid antibody test result does not exclude the diagnosis of deep-seated staphylococcal infection.

Clinical Utility

Teichoic acid antibody test is a semi-quantitative screening test used to detect antibodies to staphylococcal ribitol teichoic acid.

High titers (1:4) are frequently observed in patients with endocarditis and other deep-seated infections caused by Staphylococcus aureus.

Negative or low titers (1:2) are suggestive of an absence of underlying staphylococcal disease.
