Immunoglobulins Concentrations (IgG, IgA, IgM)

The quantitative determination of serum immunoglobulins is a useful tool in many clinical specialties. The uses of this investigation range from seeking immunoglobulin deficiency to monitoring inflammatory disease. Immunoglobulin profiles can also be a diagnostic tool in conjunction with other investigations. In such cases we are able to suggest appropriate investigations if required by the user.
