Final Answer :
A
Explanation :
Clinical evidence of a positive TST in children receiving immunosuppressive therapy, including immunosuppressive doses of steroids or who have immunosuppressive conditions, including HIV infection is an induration of ?5 mm. Children younger than 4 years of age: (a) with other medical risk conditions, including Hodgkin disease, lymphoma, diabetes mellitus, chronic renal failure, or malnutrition; (b) born or whose parents were born in high-prevalence (TB) regions of the world; (c) frequently exposed to adults who are HIV infected, homeless, users of illicit drugs, residents of nursing homes, incarcerated or institutionalized, or migrant farm workers; and (d) who travel to high-prevalence (TB) regions of the world are positive when the induration is ?10 mm. Children 4 years of age or older without any risk factors are positive when the induration is ?20 mm.
