Laboratory Management and Administration
Core concepts
This domain tests regulatory, quality, and operational knowledge. Know CLIA complexity categories (waived, moderate, high), personnel requirements, and the role of the laboratory director. Understand quality management: pre-analytic, analytic, and post-analytic phases; quality control (Levey-Jennings charts, Westgard rules), proficiency testing, and corrective action documentation.
Accreditation and safety
Recognize CAP, TJC, and CLIA requirements; biosafety levels (BSL-1 to BSL-4) and appropriate PPE; chemical and fire safety; and the chain of custody for forensic or legal specimens. Understand test utilization, turnaround time, and cost containment without compromising quality.
Traps
- Confusing quality control (internal) with proficiency testing (external).
- Forgetting that the laboratory director is ultimately responsible for quality and personnel.
- Misapplying Westgard rules (e.g., 1-3s is a warning vs. rejection rule depending on context).
- Overlooking documentation requirements for corrective actions.
Worked rule of thumb
When a control falls outside 2 SD but within 3 SD (1-2s), it is a warning; investigate but do not automatically reject. A 1-3s violation indicates random error and requires rejection and troubleshooting before reporting patient results.
