Question 2

When performing a fingerstick blood glucose test, which finger is most commonly recommended?

Accepted Answer

Ring finger (lateral aspect)

Answer

The lateral (side) aspect of the ring finger is preferred for fingerstick blood glucose testing because it has a good blood supply and is less sensitive than the fingertip, minimizing patient discomfort.

Question 3

A rapid strep test result shows a single control line with no test line. How should the medical assistant interpret this result?

The rapid influenza diagnostic test (RIDT) is a CLIA-waived immunoassay that detects influenza A and B viral antigens from nasopharyngeal swab specimens within 15 minutes.

Question 5

Why is quality control (QC) testing performed before running patient samples in the laboratory?

Accepted Answer

To ensure the reagents, equipment, and technique are producing accurate and reliable results
