text: how to separate tumour marker monoclonal ig in case of multiple myeloma by page? multiple myeloma a malignancy of plasma cells,leads to abnormal level of immunoglobulins secretion in blood.especially abnormal kappa light chains.is it that the level of igg is more?then by electrophoresis is it possible to separate. light chains are better tested with a freelite test:  a serum-based assay called freelite™, which detects and quantifies free light chains (those not associated with intact immunoglobulin), has recently become available. evidence suggests that this test may help predict the risk of progression from monoclonal gammopathy of undetermined significance (mgus) to multiple myeloma. more information on freelite™ is available at http://www.bindingsite.co.uk/freelite.asp.   igg is better tested with a spep serum protein electrophoresis to get exact levels - more igg, more "active mm is"  not sure of "by page" reference.  jewells 27 months and still here
