Question 1

Which regulatory body establishes the standards for laboratory quality systems under the Clinical Laboratory Improvement Amendments (CLIA)?

Accepted Answer

Centers for Medicare & Medicaid Services (CMS)

CMS is the federal agency responsible for administering CLIA regulations that establish quality standards for all laboratory testing performed on humans in the US.

Question 2

A histology lab is implementing a new tissue processor. Which document must be completed FIRST before the instrument goes into routine service?

Accepted Answer

Validation protocol demonstrating acceptable performance

Answer

Validation must be performed and documented before a new instrument enters routine use to confirm it produces acceptable results for patient testing.

Question 3

Under OSHA's Bloodborne Pathogen Standard, which engineering control BEST reduces needlestick injuries in a histopathology laboratory?

Accepted Answer

Self-sheathing needles or sharps with injury protection

Answer

Self-sheathing or safety-engineered sharps devices are the preferred engineering control under the Bloodborne Pathogens Standard to eliminate or minimize exposure risk.

Question 4

A laboratory receives a proficiency testing (PT) failure for H&E staining. What is the REQUIRED first step?

Accepted Answer

Perform root cause analysis and document corrective actions

Answer

CLIA requires that laboratories investigate PT failures through root cause analysis and implement documented corrective actions within a specified timeframe.

Question 5

Which temperature range is required for long-term paraffin block storage to preserve antigenicity for future immunohistochemistry?

Accepted Answer

Room temperature (20–25°C) in a cool, dark area

Answer

Paraffin blocks are best stored at room temperature in a cool, dark environment; refrigeration can cause moisture condensation that degrades block quality.
