Definitions
- the present invention relates to a method for detecting or quantifying a hepatitis C virus (HCV) antigen in serum, and a method for detecting and quantifying the same.
- HCV hepatitis C virus
- HCV has not yet produced immune sera using native virus particles or purified viral proteins due to the low viral load in the body and the lack of an in vitro growth system. ,.
- human serum the production of antibodies to antigens varies from individual to individual, and some individuals contain antibodies against antigens in one region but no antibodies against antigens in other regions.
- it since it is a polyclonal antibody, it also contains antibodies against substances other than HCV, and the results of the HCV antibody test must be determined in due consideration of cross-reactivity.
- Methods for detecting the HCV gene include NAT (nucleic acid amplification method) and DNA probe method, which are currently widely used in clinical settings.
- NAT nucleic acid amplification method
- DNA probe method which are currently widely used in clinical settings.
- High NAT test While having sensitivity, there are some difficult problems. For example,
- HCV RNA is easily degraded. For these reasons, careful handling and storage are required for routine use.
- HCV antigen detection method As an HCV antigen detection method, as shown in JP-A-8-29427, a core antigen is detected from serum using a monoclonal antibody having specificity for an epitope on HCV core antigen. Attempts have been made. This measurement method is inexpensive and can produce results in a short time (approximately 3 hours) compared to the PCR method, but has some serious problems in practical use in several respects.
- P0CT Compared to performing tests in a central laboratory, P0CT can reduce the cost of transporting specimens and equipment, and patients can undergo tests and prompt treatment at a single visit, reducing patient burden. It is reduced. In the future, in order to respond to such demands, it will be necessary to shorten the sample processing time as much as possible.
- the amount of HCV particles itself is extremely low, and therefore the amount of HCV antigen is also low, so that a more sensitive detection method is desired.

- HCV has very few virus particles per se in infected patients, and therefore contains few HCV antigens in the patient's blood.
- infected people carriers
- HCV-infected liver cancer in 10 to 30 years. Therefore, early detection and early treatment are important. It is also important to understand the pathology of HCV-infected patients for estimating the prognosis of treatment, and it is strongly desired to measure more significant HCV-related markers (antigens).
- sensitivity, specificity, reproducibility, short time, operability (fully automated), and low cost are issues that are more clinically useful, and all of them are satisfied. Therefore, it is necessary to develop it diligently.
