These processes are designed to maintain the fecal specimen’s integrity, allowing for accurate microbiome profiling, parasitic identification, and the assessment of digestive health. Tailored collection kits enhance the efficacy of sample handling, crucial for uncovering gastrointestinal conditions and informing patient-specific treatment strategies.
