Question 1

What is the Lean methodology's primary goal when applied to clinical laboratories?

Accepted Answer

Eliminating waste and inefficiency to improve workflow and reduce errors

Answer

Lean methodology in laboratories focuses on identifying and eliminating wasteful steps in workflows to improve efficiency, reduce errors, and enhance quality.

Question 2

Laboratory information systems (LIS) contribute to patient safety by:

Accepted Answer

Managing test orders, results, and specimen tracking to reduce manual errors

Answer

LIS platforms automate test ordering, specimen tracking, and result reporting, reducing transcription errors and ensuring results reach the right provider quickly.

Question 3

What does 'analytical sensitivity' mean in the context of a laboratory test?

Accepted Answer

The lowest concentration of an analyte the test can reliably detect

Answer

Analytical sensitivity defines the lowest detectable concentration of a substance, determining whether the test can find low levels of an analyte reliably.

Question 4

Diagnostic specificity in laboratory testing refers to:

Accepted Answer

The test's ability to correctly identify individuals who do NOT have the disease (true negative rate)

Answer

Diagnostic specificity measures how reliably a test produces negative results in people who truly don't have the condition, reducing false positives.

Question 5

Why do clinical laboratories participate in external quality assessment (EQA) programs?

Accepted Answer

To benchmark their performance against peer laboratories and identify systematic errors

Answer

EQA programs allow laboratories to compare their performance to peers, identify systematic biases or errors, and demonstrate competence to accreditors.
