Serum immunoglobulin concentrations in preschool children measured by laser nephelometry: reference ranges for IgG, IgA, IgM.
Serum immunoglobulin concentrations were determined on sera from 298 healthy children aged six months to six years using the Hyland laser nephelometer PDQ system. Age-specific 95% reference ranges for serum IgG, IgA and IgM are presented; considerable care has been taken to ensure statistical validity of the reference ranges. The wide range of values in children under two years suggest that mea...
متن کاملNormal value of immunoglobulins IgA, IgG, and IgM in Iranian healthy adults, measured by nephelometry.
Local reference ranges of immunoglobulins are required for studies and clinical interpretation. In this study, serum levels of IgA, IgG, and IgM in 914 Iranian healthy adult blood donor volunteers, aged 18-55 years, were measured by nephelometry. Our data showed that serum reference intervals of IgA, IgG, and IgM in subjects were 72-375, 636-1518, and 39-283 mg/dL, respectively. Data analysis s...
متن کاملSerum immunoglobulin (IgG, IgM, IgA) and IgG subclass concentrations in healthy children: a study using nephelometric technique.
Immunoglobulin (Ig) G, IgM, IgA and IgG subclass (IgG1, IgG2, IgG3, IgG4) concentrations were determined in more than 500 healthy Turkish children using nephelometric technique. These parameters were thought to be highly varied for different ethnic groups because of environmental and genetic factors. Methodology used in previous studies has been reported to affect age-related normal values. Ser...
متن کاملReference ranges for IgG subclasses in preschool children.
A normal range for IgG1, IgG2, and IgG3 subclasses has been established for children aged 6 months to 5 years using commercially available monoclonal antisera. Of particular interest were the very low concentrations of IgG2 in some healthy children, a finding which casts doubt on the importance of IgG2 deficiency reported in some patients with otherwise unexplained infections. It was not possib...
متن کاملImmunoglobulin IgG, IgM, IgA, and IgE Levels in Children with Chronic Sinusitis
Background and purpose: Sinusitis is a common disease in children that can lead to acute and chronic problems and sometimes severe complications. There is lack of evidence on underlying causes of chronic sinusitis in children in Iran, so, this study aimed to investigate the prevalence of humoral immune deficiency in patients with chronic sinusitis. Materials and methods: This cross-sectional s...
