A stool sample is processed by mixing the specimen well and straining a portion of it. Here's a detailed breakdown:
Stool Sample Processing Steps
The general process for preparing a stool sample involves:
-
Mixing the specimen: This ensures a homogenous distribution of any organisms or substances within the sample.
-
Straining the fecal suspension: Approximately 5 ml of the fecal suspension (the amount may vary based on consistency) is strained through wetted cheesecloth-type gauze. This gauze is typically placed over a disposable paper funnel into a 15 ml conical centrifuge tube. Conical paper cups with the tips cut off can be used as funnels.
This straining process removes larger particles and debris, preparing the sample for further analysis, such as microscopic examination for parasites or culturing for bacteria.
