Correct transport ensures the viability of pathogens or biomarkers in the sample, allowing accurate diagnosis of gastrointestinal infections and conditions.
A fresh stool sample should be collected using a clean, dry container. Patients should avoid contamination with urine or water. Detailed collection instructions are typically provided by the healthcare provider or lab.
Common preservatives include formalin, polyvinyl alcohol (PVA), and Cary-Blair medium. Each is selected based on the type of test being performed (e.g., parasitology, bacterial culture, or molecular testing).
Stability depends on the preservative used and storage conditions. Unpreserved samples should be processed within 2 hours, while preserved samples can typically remain stable for several days at room temperature or refrigerated.
Yes, depending on the test. Some samples should be refrigerated immediately, while others, especially for molecular assays, may require freezing. Always follow lab instructions.
Stool samples can help diagnose infections caused by bacteria (like Salmonella), parasites (like Giardia), viruses (like norovirus), and conditions like inflammatory bowel disease or malabsorption.
