quiz 2
what is considered the gold standard of diagnosis in infectious diseases?
a. white blood cell count
b. gram stain
c. temperature measurement
d. culture and antibiotic susceptibility testing
clear my choice

Explanation:

Culture and antibiotic susceptibility testing (option d) is considered the gold standard for diagnosing infectious diseases. It directly identifies the causative organism and determines which antibiotics are effective against it. A white blood cell count (option a) is a general indicator of infection but not specific. A gram stain (option b) can give a quick indication of bacteria type but not the specific organism or antibiotic sensitivity. Temperature measurement (option c) is a sign of infection but not a diagnostic test.

Answer:

d. culture and antibiotic susceptibility testing
