This organization develops standards for specimen handling and processing.

• A. CLSI
• B. CDC
• C. CLIA
• D. FDA

Answer: (A)

The main idea here is recognizing who creates formal guidelines for how specimens should be collected, handled, transported, and processed to maintain their integrity. The organization responsible is CLSI, the Clinical and Laboratory Standards Institute. CLSI develops consensus standards and guidelines used by medical laboratories to standardize preanalytical steps—from proper collection and labeling to transport conditions and processing times—so results are accurate and reliable.

This differs from other organizations: the CDC provides public health guidance and surveillance, CLIA sets regulatory standards for lab operation, and the FDA oversees approval of tests and medical devices. CLSI’s role is specifically to publish practical, evidence-based standards that labs implement to minimize preanalytic errors and ensure consistent quality across settings.
