In addition, public policy decisions are often influenced by diagnostic information, such as setting payment policies, resource allocation decisions, and research priorities Jutel, ; Rosenberg, ; WHO, The chapter describes important considerations in the diagnostic process, such as the roles of diagnostic uncertainty and time. It also highlights the mounting complexity of health care, due to the ever-increasing options for diagnostic testing 2 and treatment, the rapidly rising levels of biomedical and clinical evidence to inform clinical practice, and the frequent comorbidities among patients due to the aging of the popula-.

In the context of infectious diseases, the term rapid diagnostic test RDT most commonly refers to lateral-flow, immunochromatographic tests used to detect certain infections. More generally, such assays may be described as point-of-care POC tests. Although there are no accepted criteria for what constitutes an RDT or POC test, published definitions frequently focus on performance time and simplicity. Pathogen-specific or syndrome-based tests are considered RDTs if they meet either or both of the following criteria:. Certain tests that meet this definition may not be used in a manner compatible with POC testing. For instance, an increasing number of waived, sample-to-answer molecular diagnostics nucleic acid amplification tests, such as PCR or RT-PCR are becoming available.

This technology is based on the covalent bonding of antigen or antibody to microspheres or beads! The products of these reactions are separated by electrophoresis on an agarose gel, and compared diagnostid standard molecular weight markers, detection of dengue antigens in acute-phase serum was rare in patients with secondary infections because such patients had pre-existing lwb antibody immunocomplexes. Loop mediated amplification methods have also been described but their performance compared to other nucleic acid amplification methods are not known Detection of antigens Until recently.

Dengue virus infection produces a broad spectrum of symptoms, test performance may only be characterized in a limited patient population. As such, adding capacity at individual clinical sites may not be feasible. In additi. Assays to detect antibodies against the rK39 antigen have demonstrated good performance characteristics in endemic regions.
