Product introduction: A combined detection system for bod diarrhea virus (rotavirus, enteric adenovirus, irus, stellate virus) The system consists of BH400fx fluorescence immunoenterovirus four combination detectors and rotavirus, intestinal adenovirus, norovirus and stellate virus combination detection kit (immunofluorescence method) for the detection of diarrhoeal virus. 1. Integrated development of instruments and reagents 2. Combined multi-virus detection Product features: Combined testing of four viruses Machine detection to avoid manual reading error Detection peak height to value ratio, effectively avoid false positive, effective detection time window significantly long, within 60 minutes of reading Easy to implement full automation operation, simplify customer operation, improve work efficiency It is easy to realize informatization and can be connected with LIS and HIS Information is automatically stored for data retrieval and analysis The technical platform can be extended to more testing items Detection principle: The antigens of rotavirus, intestinal adenovirus, norovirus and stellate virus were detected by double antibody sandwich technique.When the sample under test to join hole after test card and samples, sample under test contains rotavirus and (or) the intestinal glands and/or stellate viruses and (or), such as virus antigen with fluorescently labeled antibodies to form complex reaction, in the role of chromatography, reaction compounds move forward along the nitrocellulose membrane, respectively by nitrocellulose membrane on test area package in advance by monoclonal antibody and (or) of rotavirus intestinal adenovirus monoclonal antibody and (or) star shaped virus monoclonal antibody and (or), such as virus monoclonal antibody capture, forming reaction zone in the testing area, using fluorescence immunoassay analyzer to detect the reaction with fluorescence value, When the fluorescence value is equal to or higher than the detection limit, it is positive. When the fluorescence value is lower than the detection limit, it is negative, thus realizing the purpose of detecting rotavirus, intestinal adenovirus, stellate virus and norovirus. Technical parameters: Analysis method: immunofluorescence Measurement range: fluorescein solution with a concentration range of 0-500ng/ml can be detected, within which the linear correlation coefficient r should be greater than or equal to 0.990. Signal-noise background: the instrument was used to detect the blank reagent card for 10 consecutive times. The mean value was calculated. The background fluorescence intensity of the noise was less than 50. Accuracy: the fluorescein calibration product is determined by the instrument and the determination value should be within 5% or 5% of the indicated value. Precision: fluorescein solution with a concentration of 100ng/ml was taken as a sample for testing, and the variation coefficient was less than 10% Accuracy: within 20 minutes of the instrument, the fluorescence intensity indicator changes less than 5% Test time: a full measurement time less than 30 seconds Power supply: voltage 220V; Frequency 50 hz Working conditions: A) indoor use B) the altitude is below 2000m C) environmental temperature: 10 ℃ ~ 30 ℃; Relative humidity: less than or equal to 70%. D) the instrument shall not be disturbed by vibration, corrosive gases and electromagnetic fields that affect its use. Dimensions: 400 * 436 * 200 (mm)
