Question 1

When using a point-of-care urine immunoassay cup, a temperature strip reading of 90–100°F indicates which of the following?

Accepted Answer

The specimen temperature is within acceptable range for a fresh void

Answer

A temperature between 90–100°F confirms the urine was freshly voided from the body, meeting validity requirements.

Question 2

What is the primary purpose of performing quality control (QC) runs on an onsite immunoassay drug testing analyzer?

Accepted Answer

To ensure the instrument is performing within acceptable accuracy parameters

Answer

QC runs with known-positive and known-negative controls verify that the analyzer's results are accurate and reliable before testing patient specimens.

Question 3

A clinic's breathalyzer displays an 'Err 4' fault code during a patient test. What is the most appropriate next step?

Accepted Answer

Refer to the manufacturer's troubleshooting guide and do not use the device until the error is resolved

Answer

Error codes indicate a device malfunction; the manufacturer's guide must be consulted and the device must be taken out of service until the issue is corrected.

Question 4

Gas chromatography-mass spectrometry (GC-MS) is used as a confirmatory test for drug screening primarily because it:

Accepted Answer

Provides high specificity by identifying the exact molecular structure of a compound

Answer

GC-MS identifies compounds by their unique molecular fragmentation pattern, making it highly specific and resistant to cross-reactivity false positives.

Question 5

Which of the following best describes the correct procedure for reading a urine drug test strip after the manufacturer's specified reaction time has elapsed?

Accepted Answer

Any line present, regardless of intensity, in the test region indicates a negative result

Answer

On a competitive immunoassay strip, any visible line in the test region—regardless of intensity—indicates a drug concentration below the cutoff and is read as negative.
