Description
Os testes para diagnóstico da COVID-19 são uma
das maiores armas que a Humanidade tem de se
apetrechar para conseguir conter a pandemia,
pois estes irão permitir identificar os portadores e
naturalmente isolá-los de contatos com outros Seres
Humanos e assim conter as cadeias de transmissão.
Mas a capacidade destes testes, nomeadamente
no que diz respeito aos seus valores intrínsecos
(sensibilidade e especificidade) e extrínsecos
(valores preditos positivo e negativo), em função
da prevalência da doença, é fundamental, para a
obtenção de uma melhor precisão dos resultados e
definição de um plano estratégico de testagem. A
eventual inexistência de um teste “gold standard”
é uma das maiores limitações para já. Assim, com
este trabalho, pretendemos fazer uma análise
da capacidade de diagnóstico destes testes e da
importância que os mesmos podem ter para o
combate à pandemia causada pelo SARS-CoV-2.
Abstract The diagnostic tests for COVID-19 are one of the greatest weapons that Humanity has to equip itself to be able to contain the pandemic, as these will allow to identify the carriers and naturally isolate them from contacts with other Human Beings and thus contain the chains of streaming. But the capacity of these tests, namely with regard to their intrinsic (sensitivity and specificity) and extrinsic (positive and negative predicted values) values, depending on the prevalence of the disease, is essential, in order to obtain a better precision of the results and definition of a strategic testing plan. The lack of a “gold standard” test is one of the biggest limitations for now. Thus, with this work, we intend to make an analysis of the diagnostic capacity of these tests and the importance that they may have in combating the pandemic caused by SARSCoV- 2.
