Question 1

Which turnaround time (TAT) metric measures the time from when a specimen is received in the laboratory to when the result is reported?

Accepted Answer

Laboratory TAT

Answer

Laboratory TAT measures the internal processing time from specimen receipt to result reporting, which is directly controllable by laboratory operations.

Question 2

A laboratory implements a new test for a rare analyte and receives no proficiency testing samples from an approved PT program. What should the laboratory do?

Accepted Answer

Perform alternative assessment such as split-sample comparison with another lab

Answer

When approved PT is unavailable, CLIA requires laboratories to verify test accuracy using alternative methods such as split-sample testing with reference laboratories.

Question 3

What does 'lean laboratory' methodology primarily aim to eliminate?

Accepted Answer

Waste and non-value-added steps in laboratory processes

Answer

Lean methodology focuses on identifying and eliminating waste (unnecessary steps, waiting time, motion) to improve efficiency and reduce TAT.

Question 4

Which document must a laboratory maintain that describes the range and type of tests offered, specimen requirements, and reference intervals?

Accepted Answer

Laboratory test catalog (or test menu)

Answer

A laboratory test catalog provides clinicians with essential information about available tests, specimen requirements, reference intervals, and turnaround times.

Question 5

Under CLIA, which personnel category is authorized to perform high-complexity testing?

Accepted Answer

Qualified laboratory scientists meeting education, training, and experience requirements for high-complexity testing

Answer

High-complexity testing requires personnel who meet specific education and training standards defined in CLIA regulations, typically including laboratory scientists with relevant degrees.
