Meeting the needs for haematologists and clinical chemists for an up to date reference, this atlas provides a visual presentation of lymphoproliferative disorders, leukaemia and plasma cell neoplasms. Blood tests may also be ordered to measure levels of intact immunoglobulins (e.g., IgG, IgM, IgA). Immunoglobulin light chains are usually cleared from blood through the renal glomeruli and reabsorbed in the proximal tubules so that urine light-chain concentrations are very low or undetectable. Serum free light chains can also be increased, usually with a normal kappa/lambda ratio, with some connective tissue disorders, inflammatory conditions, neurological conditions, and some cancers but are not typically monitored in people with these conditions. Some serological tests are not limited to blood serum, but can also be performed on other bodily fluids such as semen and saliva, and Spinal fluid (CSF) which may contain antibodies.This book starts with a small historical introduction to Leukemia. 2016 Aug;17(8):e328-46.

Background: We report a case of immunoglobulin (Ig) D myeloma with hidden lambda light chains in a patient whose immunofixation test was very difficult to interpret: the IgD reacts with the anti- heavy chain antiserum but does not react with anti-lambda antiserum. Plasma cell disorders are routinely diagnosed using serum and urine protein electrophoresis tests (SPEP/UPEP), followed by immunofixation electrophoresis (IFE) tests to determine which immunoglobulin is present in excess. The presence of a monoclonal light chain M-spike of greater than 1 g/24 hours is consistent with a diagnosis of multiple myeloma or macroglobulinemia.

Immunoglobulin light chain (AL) amyloidosis is the most common form of systemic amyloidosis, accounting for approximately 70% of all subjects suffering from these diseases. A minority of people with MGUS will later develop multiple myeloma. - Laboratory Screening Tests for Suspected . HLCr together with SIFE/UIFE identified clonality in 94% patients; the combination with FLCr yielded 100% sensitivity. - Laboratory Screening Tests for Suspected . Serum free light chain analysis accelerates the detection of treatment response because the free light chains have a much shorter half-life (3-5 hours) than intact immunoglobulins (about 21 days). Serum free light chain (SFLC) testing is ordered to help detect, diagnose, and monitor plasma cell disorders (dyscrasias), including multiple myeloma, primary amyloidosis, and related diseases or to monitor the effectiveness of treatment.

Monitoring serum from patients with monoclonal light chain diseases without a M-spike on protein electrophoresis. Also called kappa and lambda light chains, they link together with other proteins (heavy chains) to form immunoglobulins (also known as antibodies) that target and neutralize specific threats to the body such as bacteria and viruses.
