Test ID: SALMC
Salmonella Culture, Feces
Testing Algorithm 
Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
When this test is ordered, the reflex tests may be performed and charged separately.
See Laboratory Testing for Infectious Causes of Diarrhea in Special Instructions.
Specimen Type Describes the specimen type validated for testing
Advisory Information
The recommended test for diagnosis of typhoid or paratyphoid fever is blood culture.
Additional Testing Requirements
If susceptibility testing is needed, also order ZMMLS / Antimicrobial Susceptibility, Aerobic Bacteria, MIC, Varies. If susceptibility testing is not needed (eg, due to lack of recovery of Salmonella species from feces), it will not be performed and the ZMMLS order will be canceled at time of report.
In some cases, local public health requirements may impact Mayo Clinic Laboratories clients, requiring, for example, submission of isolates to public health laboratories. Clients should familiarize themselves with local requirements and are responsible for submitting isolates to appropriate public health laboratories. Clients can obtain isolates of Salmonella species recovered from specimens submitted to Mayo Clinic Laboratories by calling 800-533-1710 as soon as possible after reporting (to ensure viability of the bacterium).
