To evaluate the quality of a diagnostic test, important variables such as sensitivity and specificity are considered to measure and identify the diagnostic accuracy of the method. Regarding the Kato-Katz method, it is safe to say that: Incorrect answer. A. It has high specificity and high sensitivity. It has low sensitivity because egg counting can be inaccurate, as it depends on the technician who will evaluate it. In addition, a low parasite load may not be detected by the technique.
a) It has high specificity and high sensitivity.
b) It has low sensitivity because egg counting can be inaccurate, as it depends on the technician who will evaluate it. In addition, a low parasite load may not be detected by the technique.

A resposta correta é a alternativa b) "It has low sensitivity because egg counting can be inaccurate, as it depends on the technician who will evaluate it. In addition, a low parasite load may not be detected by the technique." A técnica de Kato-Katz tem baixa sensibilidade devido à possibilidade de erro na contagem de ovos, que depende do técnico que irá avaliá-la. Além disso, uma baixa carga parasitária pode não ser detectada pela técnica.
