✍️ Sample CLT Questions & Answers
1. Which element is NOT typically required on a laboratory specimen label?
A technologist's home address is never required; labels must include patient identifiers, collection date/time, and specimen ID.
2. What should a clinical laboratory technologist do in case of a spill or contamination?
In the event of a spill or contamination, a clinical laboratory technologist must immediately follow established safety protocols. This includes containing and cleaning the spill using appropriate materials and techniques to prevent further spread of hazardous substances or infectious agents. Promptly notifying a supervisor is also critical for ensuring proper documentation, assessing potential risks, and implementing any necessary corrective actions to maintain a safe working environment.
3. What documentation is required when equipment is replaced or upgraded?
Proper documentation of replacements includes asset tracking, disposal records, and updated procedures to maintain compliance and ensure staff are trained on new equipment.

Delta checks compare a patient's current result to a previous result and flag unexpected changes that may indicate specimen mix-up or analytic error.
5. A co-oximeter in the blood gas laboratory requires a reference solution check. The purpose of this check is to:
Co-oximeters use multiple wavelengths to distinguish oxyhemoglobin, deoxyhemoglobin, carboxyhemoglobin, and methemoglobin; reference solution checks verify wavelength calibration.
6. A laboratory's Levey-Jennings chart shows 6 consecutive QC values all falling on the same side of the mean. Which Westgard rule is violated?
The 10x rule is triggered when 10 consecutive QC values fall on the same side of the mean, indicating a systematic shift; 6 consecutive points triggers the 6x warning rule.
