A. Patient's house

B. Clinic

C. Hospital

Answer:

Stool samples are typically collected at the patient's house or at a clinic.

Stool samples are generally collected at the patient's home or at the hospital/lab clinic. The samples are collected in clean, dry, leak-proof containers and should ideally be examined within two hours of collection. If it's not possible to examine the sample within this time, it must be preserved at the correct temperature depending on the preservative used.

The sample is then subjected to various tests such as microscopic examination sometimes over several days, and serologic testing. These methods help identify the cause of any intestinal disorders that the patient might be suffering from, by identifying the presence of harmful bacteria, blood, or certain parasites.

Some of these tests involve the use of immunoassays, enzyme immunoassays, and nucleic acid amplification tests like PCR (polymerase chain reaction). These tests help detect the presence of infectious agents like bacteria and parasites, and also help identify the presence of blood in the stool, which could be indicative of certain health conditions.
