When to Seek Prompt Care

Seek urgent medical care if you experience severe dehydration, signs of electrolyte imbalance (like extreme weakness or confusion), bloody diarrhea, high fever, or symptoms that worsen rapidly. These could indicate a serious infection requiring immediate attention.

What It Measures

A stool culture is a lab test. It checks your poop for certain germs. These germs can make your stomach and intestines sick. This test helps tell apart good germs from bad germs. The bad germs can cause an infection.

Why It's Ordered

Your doctor may order this test if they think you have a stomach or intestine infection. This is especially true if you have bad diarrhea, belly pain, or throwing up for several days.

Reference Range

Reference ranges for stool cultures are qualitative (positive/negative) and can vary by lab. Interpretation also depends on your symptoms and clinical history.
