The collection of a stool sample for culture involves the following steps: 1. Preparation: Educate the patient on the need for the test and how to collect the sample properly. 2. Collection Kit: Provide the patient with a sterile collection container. 3. Instructions: Inform the patient to avoid contaminating the sample with urine or toilet water. It's often best to use a clean, dry container placed in the toilet bowl to catch the stool. 4. Submission: The collected sample should be delivered to the laboratory as soon as possible, ideally within two hours, to ensure accurate results.
