Salmonella: Diagnosis and Tests
How is salmonella diagnosed?
Salmonella symptoms are vague and can be caused by many illnesses. The only way to know for sure that diarrhea, cramps, and fever are caused by Salmonella infection is by a lab test on the sick person’s stool.
There are more than 2,000 different types of salmonella bacteria that cause people to get sick. Certain antibiotics do not work against some of these types. If the sick person goes to the doctor, the doctor may order additional lab tests on the bacteria in the stool sample to identify the type of salmonella. This information will help the doctor decide what antibiotic to use if that person needs treatment.
