Question 1

What is the chain of custody in forensic and clinical laboratory specimens?

Accepted Answer

A documented record tracking who handled a specimen from collection to final disposition

Answer

Chain of custody documentation ensures that every person who handled a specimen is recorded, preserving the specimen's legal and scientific integrity.

Question 2

Why is proper specimen labeling critical in clinical laboratory medicine?

Accepted Answer

Mislabeled specimens can result in a wrong patient receiving incorrect test results or treatment

Answer

Mislabeling a specimen can cause results to be attributed to the wrong patient, leading to incorrect diagnoses and potentially harmful treatment decisions.

Question 3

The clinical significance of a reference range in laboratory testing is that it:

Accepted Answer

Defines the range of values observed in a healthy reference population, helping interpret patient results

Answer

Reference ranges represent the central 95% of values in a healthy population and provide context for interpreting whether a patient's result is unusual.

Question 4

Critical values in clinical laboratory reporting require:

Accepted Answer

Immediate notification to the responsible clinician due to the life-threatening nature of the result

Answer

Critical values represent results at life-threatening extremes that require immediate clinician notification so urgent intervention can be initiated.

Question 5

Point-of-care testing (POCT) differs from central laboratory testing in that it:

Accepted Answer

Is performed near the patient using portable devices, enabling faster clinical decisions

Answer

POCT is performed at or near the patient using portable analyzers, reducing turnaround time and enabling rapid clinical decisions in urgent situations.
