Overview
The primary purpose of DNA extraction from stool is to obtain pure DNA for molecular analysis. This can help in: 1) Detecting genetic mutations linked to colorectal cancer. 2) Identifying pathogens or parasites in the gut. 3) Analyzing the gut microbiome composition. 4) Diagnosing inflammatory bowel disease. 5) Monitoring treatment response in gastrointestinal conditions.
