Summary of "The establishment and clinical evaluation of a novel, rapid, no-wash one-step immunoassay for the detection of dengue virus non-structural protein 1."

Dengue fever is a highly endemic arthropod-borne viral disease in the tropical and sub-tropical countries and is rapidly becoming a global threaten. Diagnosis has been conducted by either traditional serological methods or molecular biological techniques. However, these methods are either labor-intensive, time-consuming or with multiple steps, which are not suitable for high throughput detection of large quantity of samples. In the current study, a novel, rapid, no-wash one-step amplified luminescent proximity homogenous assay-linked immunosorbent assay (AlphaLISA) was developed and optimized for the diagnosis of dengue fever through the detection of dengue virus non-structural protein 1 (NS1). The linear range of the assay was determined to be 60,000 pg/mL to 200 pg/mL, with a lower detection limit of 127.45 pg/mL for NS1 protein. The precision of the assay was 8.24% and 4.93% for the high and low concentration. Clinical evaluation indicated that the sensitivity and specificity of the assay was 91.49% and 81.54%, respectively. This novel, rapid, no-wash one-step AlphaLISA assay is convenient and sensitive, which could be a good alternative for the screening of dengue fever in a high throughput format.
