Question

Immunologic assays are some of the most frequently performed methods for the detection of

viral antigens from clinical material. Direct immunofluorescent (DFA) assays are rapid and
highly specific and are commonly used for detecting, which of the following?
Select one:
a. RSV, HCV and influenza viruses
b. Influenza viruses, adenovirus, and RSV
c. HIV, adenovirus, and HS
d. HCV, HPV, and HSV

Answer 1

Direct immunofluorescent (DFA) assays are commonly used for detecting influenza viruses, adenovirus, and RSV.

Step-by-step explanation:

Direct immunofluorescent (DFA) assays are commonly used for detecting viral antigens from clinical material. These assays are rapid and highly specific. In the given options, DFA assays are used for detecting influenza viruses, adenovirus, and RSV. Therefore, option b, 'Influenza viruses, adenovirus, and RSV' is the correct answer.
