Indicators for Testing
Stool testing is generally reserved for severe cases of diarrhea. Indicators include high fever, dehydration, or persistent symptoms lasting more than a week. Those with bloody stools or at high risk, like healthcare workers and the elderly, should also consider testing.
Types of Tests Available
Stool cultures are the most common diagnostic tests to identify bacterial causes. Multiplex molecular panels are also available, which can detect a wider range of pathogens, including viruses and parasites. Your healthcare provider will choose the appropriate test based on symptoms and risk factors.
The Testing Process
A sample is collected when symptoms peak, ensuring the highest chance of detecting the pathogen. The sample is then analyzed in a lab, and results guide the treatment plan. Testing is crucial for public health concerns and preventing outbreaks.
