Used in diagnostic research to detect antibodies or antigens related to the Human Fever with Thrombocytopenia Syndrome Virus (SFTSV) in human serum or plasma samples. The kit enables quantitative or qualitative measurement of immune responses, supporting epidemiological studies, clinical diagnosis investigation, and monitoring of SFTSV infections. It is a critical tool in virology laboratories for early detection, outbreak analysis, and evaluation of potential therapeutics or vaccines. The ELISA format allows high-throughput screening with reliable sensitivity and specificity under controlled research conditions.
