Diagnostic tests for active tuberculosis (TB) based on the detection of antibodies (serological tests) have been commercially available for decades, although no international guidelines have recommended their use. An estimated 1.5 million serological TB tests, mainly enzyme-linked immunosorbent assays, are performed in India alone every year, mostly in the private sector. The cost of serologica...
OBJECTIVE The aims of this study were to describe the clinical presentation of primary SS (pSS) in a large cohort of patients by assessing the prevalence of the patient subgroups at high risk for severe extraglandular manifestations and to explore the influence of the patients' serological profile on disease severity and on immunosuppressive drug utilization. METHODS Cumulative demographic, c...
Visceral leishmaniasis (VL) is a zoonotic disease caused by leishmania species. Dogs are considered to be the main reservoir of VL. A number of methods and antigen-based assays are used for the diagnosis of leishmaniasis. However, currently available methods are mainly based on direct examination of tissues for the presence of parasites, which is highly invasive. A variety of serological tests ...
BACKGROUND Serological studies can detect infection with a novel influenza virus in the absence of symptoms or positive virology, providing useful information on infection that goes beyond the estimates from epidemiological, clinical and virological data. During the 2009 A(H1N1) pandemic, an impressive number of detailed serological studies were performed, yet the majority of serological data w...
Strategies for the prevention of cancer include those aimed at reducing the incidence of cancer (primary prevention) and cancer mortality through early detection of tumors (secondary prevention). The efficacy of prevention interventions is evaluated by clinical trials. The conduct of clinical trials is aided by the use of serological indicators of the carcinogenic process measured using plasma ...
a living body produces in the body antisubstances which react with the substance is an antigen. The anti-substance is an antibody which is found in the blood, plasma or serum and is contained in the serum globulin. Serological reactions are antigen-antibody reactions. They are also called immunological reactions or biological reactions. The serological technique sets up these reactions. It is a...
The aim of the present was to evaluate the prevalence of H9N2-specific antibodies among water buffaloes (Bubalus bubalis). To this end, blood samples were obtained from 80 randomly selected water buffaloes, 40 cases of which were obtained in the winter months, and 40 cases were sampled in the spring months. The presence of H9N2-specific antibody was determined by hemaggl...
