Which statement best describes the role of following QA processes in the NHCO order of draw?

• A. To increase test turnaround time
• B. To comply with billing codes
• C. To reduce pre-analytical errors and ensure specimen integrity
• D. To confuse the laboratory staff

Answer: (C)

Preventing pre-analytical errors and preserving specimen integrity is what QA in the NHCO order of draw is all about. Following the prescribed draw order and QA checks ensures that additives from one tube don’t contaminate the next, which could skew test results. Standard QA steps—accurate patient identification, selecting the correct tube type and fill volume, proper mixing, prompt and accurate labeling, and proper handling and transport—work together to minimize issues like contamination, improper labeling, clotting, or hemolysis. By reducing these errors, test results become more reliable and the need for repeat draws decreases. The other options miss the core purpose: QA isn’t about speeding up turnaround as the primary goal, nor is it about billing codes, and it certainly isn’t about confusing staff.
