LP14907-7   Beta-2-Microglobulin
β2-Microglobulin (β2-M) is a low-molecular weight protein that is the light chain of the class I MHC (major histocompatibility complex) antigens. Present in all nucleated cells and almost totally reabsorbed and catabolized by the proximal tubules, it is a marker of immune activation and proximal tubular function and found in nearly all body fluids. Because it accumulates with renal dysfunction and deposits in tissues, β2-M is a cause of dialysis related amyloidosis. Levels are also elevated in conditions such as chronic inflammation, liver disease, renal dysfunction, and some acute viral infections. It is found in many hematological malignancies and thus a valuable treatment monitor and prognostic marker, particularly for multiple myeloma. [Tietz] Source: Regenstrief LOINC

LP32035-5   Creatinine
Creatinine or creatine anhydride, is a breakdown product of creatine phosphate in muscle. The loss of water molecule from creatine results in the formation of creatinine. It is transferred to the kidneys by blood plasma, whereupon it is eliminated by glomular filtration and partial tubular excretion. Creatinine is usually produced at a fairly constant rate and measuring its serum level is a simple test. A rise in blood creatinine levels is observed only with marked damage to functioning nephrons; therefore this test is not suitable for detecting early kidney disease. Creatine and creatinine are metabolized in the kidneys, muscle, liver and pancreas.
