Deck 24: Immunologic Based Rapid Testing

Question 1

Most rapid tests provide a quantitative measure of the analyte that is being tested.

Answer 1

False
Most rapid test procedures provide a qualitative measure of the analyte being tested; this means that they provide a positive or negative result.

Question 2

Which of these is an example of an immunology specialty area of study?

A)Infectious disease
B)Immunoassay
C)Platelet function studies
D)Hepatic function analysis

Answer 2

A
Immunoassay refers to a testing method rather than a specialty area of study. Platelet function studies are a type of coagulation test, and the analysis of hepatic function would not necessarily have anything to do with immunology.

Question 3

Do all rapid HIV tests offer an opportunity for oral samples to be tested?

Answer 3

No, only one type of test (OraQuick) offers an opportunity for an oral sample to be tested.

Question 4

Confirmatory tests are always necessary for CLIA-waived HIV procedures that yield a positive result.

Question 5

A)Sore throat and swollen tonsils
B)Fatigue and sore throat
C)Gastric upset and acid reflux
D)Lower respiratory tract congestion and rhinorrhea

Question 6

A)Mononucleosis
B)Helicobacter pylori
C)The presence of HCG
D)Group A streptococcus

Question 9

Plasma, serum, urine, or whole blood may be used for CLIA-waived HCG or mononucleosis testing.

Question 10

Urine pregnancy tests may only be performed on first morning void specimens.

Question 11

Provide examples of two situations when QC must be performed for rapid HIV tests.

Question 12

A sales representative comes in to the office to explain a new procedure for HIV testing. She explains that this procedure has greater specificity than the one currently in use by the office. This means:

A)The new HIV test can detect the HIV antibody at a lower level of concentration.
B)The new HIV test provides a quantitative result.
C)The new HIV test is better at detecting only the HIV antibody rather than other similar substances.
D)The new HIV test needs no quality control to verify its performance.

Question 13

Antigen-antibody reactions are visible as clumps in this type of reaction:

A)Lateral-flow immunoassay
B)Colorimetric tests
C)Chromatographic tests
D)Agglutination

Question 14

Rapid tests are performed only in physician office laboratories.Completion
Complete each statement.

Question 15

Question 16

Sam is performing a CLIA-waived test for group A strep. The patient asks whether this is a quantitative test procedure. How should Sam answer the question?

Question 17
