Testing significance: Different susceptible respiratory viruses vary in the infection latency, acute phase and course of disease, so that the identification of infected pathogen is conductive to the pre-judgment of therapeutic medication and disease course, and prevention against any complication. 

Pathogen antigen testing occurs earlier, while IgM antibody occurs slightly later, of which their windows generally overlap for 3-5 days. Although the pathogen antigen testing plays a favorable role in the early diagnosis, it has a very short window, facing the fact that, immediately after their appearance, the specific antibody will form an immune complex with the pathogen. At this time, the antibody labeled by the testing reagent has been blocked at the antigen epitope of pathogen, resulting in the false negative results and finally leading to the invalid testing. 

Moreover, the convenient and rapid testing and the reduction of hospital resource cost are also advantages of our gold standard products. Specific advantages are introduced in the following table. 

Explain the clinical situation of mumps testing. As reported by the 2011 Analysis on Serum IgM Antibody Level of Mumps Patients in Jinan and Its Influence Factors, among 780 mumps patients, ELISA method is of an IgM detectable rate of 23%, and accompanied by 30% covert infection. Moreover, it is unnecessary to identify again after there is a symptom. Furthermore, it is of greater significance that the clinical testing of silent infection or early infection of the respiratory tract is tested out clinically than direct testing of the symptomatic patients.
