Salmonella typhi and paratyphi Antibodies
Also known as: STYPHI
Use
This test is used to determine past exposure to Salmonella typhii (infection or vaccination) and Salmonella paratyphi. It cannot confirm acute salmonellosis. For systemic symptoms of acute salmonellosis, alternative tests like Stool Culture, E. coli Shiga-like Toxin by EIA, and Blood Culture are preferred if typhoid fever is suspected.
Special Instructions
This test is New York state approved, ensuring compliance with local regulatory requirements. Specimens contaminated, heat-inactivated, hemolytic, icteric, lipemic, or turbid may be rejected.
Limitations
The test cannot confirm acute salmonellosis and cross-reactivity with other Salmonella species cannot be excluded. Thus, a positive result does not necessarily indicate an active infection and further clinical correlation is required.
