Commercially available diagnostic test kits for detection of dengue virus (DENV) non-structural protein 1 (NS1) and anti-DENV IgM were evaluated for their sensitivity and specificity and other performance characteristics by a diagnostic laboratory network developed by World Health Organization (WHO), the UNICEF/UNDP/World Bank/WHO Special Programme for Research and Training in Tropical Diseases...
The current COVID-19 pandemic is caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). A better understanding of its immunogenicity can be important for development improved diagnostics, therapeutics, and vaccines. Here, we report longitudinal analysis three patients with moderate (#1) mild disease (#2 #3). Antibody serum responses were analyzed using spike glycoprotein en...
The performance of a commercial rapid immunochromatographic dengue IgG/IgM assay device was evaluated against an in-place dengue IgM-capture ELISA in the National Public Health laboratory. Of the 239 serum samples from patients with clinical diagnosis of acute dengue illness, 140 and 99 samples were tested positive and negative respectively for anti-dengue IgM by the in-placed ELISA. Comparativ...
BACKGROUND Laboratory diagnosis of syphilis is usually accomplished by serology. There are currently a large number of different commercial treponemal tests available that vary in format, sensitivity and specificity. AIM To evaluate the ID-PaGIA Syphilis Antibody Test as an alternative to other specific treponemal tests for primary screening or confirmation of diagnosis. METHODS Serum sampl...
background and objectives: brucellosis is one of the most common zoonotic diseases in iran and human brucellosis is endemic in all parts of the country. because of the difficulty in the diagnosis of brucellosis, particularly in endemic areas, the use of new and feasible diagnostic tests seem to be of great importance for resolving the diagnostic obstacles. we evaluated the usefulness of a new s...
We determined the presence of IgG and IgM antibody to viral capsid antigen (VCA-IgG, VCA-IgM) and IgG antibody to the Epstein-Barr virus nuclear antigen (EBNA) by indirect immunofluorescence assay (IFA) and enzyme-linked immunosorbent assay (ELISA) during the acute illness and at 1, 2, 6, and 48 months in a prospective population-based case series of 95 persons with an acute illness serological...
Hand, foot and mouth disease (HFMD) is a common childhood infection caused by many enteroviruses, including enterovirus A71 (EV-A71). As EV-A71 is associated with severe neurological disease, early diagnosis is critical for clinical and public health management. In developing countries such as Malaysia, laboratory capacity to carry out EV-A71 IgM detection is greater than that of the gold stand...
BACKGROUND Acute toxoplasmosis in pregnant women presents a high risk of Toxoplasma transmission to the fetus. Early diagnosis is difficult, especially when serological testing for IgG/IgM antibodies fail to differentiate between a recent and a past infection. In this case, we rely on IgG avidity or PCR assays. OBJECTIVES The aim of this study was to compare conventional ELISA and IgG avidity...
For the evaluation of autoantibodies in Pemphigus vulgaris (PV), an indirect ELISA assay was developed by using a semi-purified human epidermal skin extracted with approximately a molecular weight (M.W.) of 130-160 kDa. The evaluation of Pemphigus IgG, IgM and IgA autoantibodies in 75 patients and 50 control sera indicated that this indirect ELISA assay was a useful method for the detection of ...
Blood specimens from 133 patients clinically diagnosed as dengue virus infection by physicians in Nakhon Phanom Hospital, Thailand, were examined to detect anti-dengue IgM and IgG antibodies by antibody capture ELISA. The blood specimens were divided into 3 types of storage; (1) frozen serum aliquots, (2) whole blood dried on filter paper strips, and (3) sera dried on filter paper strips. These...
