Use of Quantiferon Gama in the diagnosis of meningeal tuberculosis in the child: a case report

There are several forms of infection by the M. tuberculosis bacillus, the meningeal is the most serious of them. Because it has serious side effects and a long treatment, the precise diagnosis is essential to justify the early treatment of the disease. Traditional diagnostic methods are often insufficient, requiring the use of more modern tests, which, despite higher costs, have lower rates of diagnostic errors. Therefore, it is necessary to use tests with greater sensitivity and specificity, such as the Quantiferon Gamma. We report the case of a male patient, 10 years old, admitted for headache, drowsiness, vomiting and neck stiffness. Traditional exams did not help in the diagnosis, requiring Quantiferon Range (QTF-G) for diagnosis of TB.
