OBJECTIVE To conduct an external quality assessment (EQA) of dengue and chikungunya diagnostics among national-level public health laboratories in the Asia Pacific region following the first round of EQA for dengue diagnostics in 2013. METHODS Twenty-four national-level public health laboratories performed routine diagnostic assays on a proficiency testing panel consisting of two modules. Mod...

A procedure has been developed in which Salmonella can be detected in dried foods and feeds within 50 hr. This includes preenrichment (18 hr), selective enrichment (24 hr), elective enrichment (6 to 8 hr), and serological testing (2 hr). The procedure is as sensitive as the more time-consuming, traditional (plating, biochemical, and serological) procedure which may require at least 4 to 5 days....

As no published results were available of valid evaluations of common serological reactions found amongst the various racial groups of South Africa, the serological department of the Natal Pathological Service initiated a comprehensive investigation of these reactions in the racial groups of Natal. It is hoped to publish the results in a series of papers. This paper reports the results of testi...

The ABO blood group system was the first to be discovered; still, there is an enigma in subgroups. A1 and A2 phenotypes account for about 99% of all A or AB individuals, rest are weaker They usually suspected cases discrepancies. Meticulous serological testing with technical expertise will help differentiate these We describe a case healthy donor discrepancy due weak subgroup 'A' group.

The serological testing is important for diagnosis of patients and for knowledge the distribution of the parasite in different territories. To assess the level of the infection in the healthy population and to establish prevalence of antiEchinococcus antibodies, we performed a serological screening in 683 people without any symptoms of disease. Six counties from Transylvania were investigated: ...

Four serological tests and three immunofluorescence tests for IgG, IgM, and IgA were compared for value in the investigation of brucellosis in veterinary surgeons. No one serological test stood out over the others, and the immunofluorescence tests did not appear to have advantages over the serological tests. If a laboratory is limited in time and resources then the saline agglutination or the c...

BACKGROUND There has been a growing recognition that coeliac disease is much more common than previously recognised, and this has coincided with the increasingly widespread use of serological testing. AIM To determine whether the age at presentation and the clinical presentation of coeliac disease have changed with the advent of serological testing. METHODS A 21-year review of prospectively...

Zoonotic visceral leishmaniasis is caused by Leishmania infantum (L. infantum),and its major reservoir hosts are domestic dogs, most of which are asymptomatic. This study aimed to detect L. infantum spp. in asymptomatic stray dogs by molecular and serological methods in Mashhad, Iran, during 2011-12. In this study, 94 asymptomatic stray dogs were randomly selected and their blood samples were c...

Development of serological and nucleic acid testing (NAT) has revolutionized hepatitis C virus (HCV) diagnosis. Although third generation anti-HCV enzyme immunoassays (EIAs) are very effective for testing high prevalence populations, confirmatory testing is still necessary when these tests are applied to populations with a low HCV prevalence to exclude false positive results. Limitations of thi...

Serological tests for syphilis (STS), as well as being important aids in the diagnosis of syphilis in man, are important in the study of experimental syphilis in animals. Rabbits not infected with Treponema pallidum sometimes show reactivity in one or another of the several available serological tests for the disease and, with the exception of the enzootic rabbit-spirochaetosis caused by Trepon...
