Zusammenfassung
β2-Mikroglobulin ist ein Plasmaprotein niedrigen Molekulargewichts (11800), das in geringen Mengen auch im Harn und Liquor vorkommt. Seine Serumkonzentration liegt bei gesunden Kindern bei 0,12±0,04 mg/100 ml, seine renale Ausscheidung bei 0,07±0,05 mg/24 Std. Bei glomerulärer Nephropathie sind die Serumspiegel bei eingeschränkter GFR erhöht, während bei tubulärer Nephropathie die Ausscheidung im Harn erheblich gesteigert ist. Es besteht eine enge Korrelation zwischen β2-Mikroglobulin und der GFR.
β2-microglobulin in healthy children and in children with renal diseases
Abstract
β2 microglobulin is a plasma protein of low molecular weight (11800), which also appears in urine in small quantities and cerebrospinal fluid. Its serum concentration in healthy children is 0.12±0.04 mg/100 ml, its renal excretion is 0.07±0.05 mg/24 hrs. In glomerular nephropathy serum levels are augmented with diminished GFR, while in tubular nephropathy excretion in the urine is raised considerably. There is a close correlation between serum β2 microglobulin and GFR.
