Intended Use
Good Biotech Corp. Beta2-microglobulin LIT Assay (REF: KT-0202-A) is intended to be used for the quantitative determination of Beta2-microglobulin in human serum and urine by latex particle enhanced immunoturbidimetry (LIT). The measurement of Beta2-microglobulin aids in the diagnosis of renal function such as glomerular and tubular kidney disease. For In Vitro Diagnostic Use.
Features
The one and only IgY-based Human Beta2-microglobulin immunoassay in the world.
Application for general clinical chemistry analyzers.
Ready-to-use reagent.
No sample dilution in ordinary assay range (Serum: 0.1~20 mg/L, Urine: 0.01~8 mg/L).
No Hook effect up to 150 mg/L.

Detection limit: ~ 0.05 mg/L
The lower detection limit represents the lowest measurable beta2-microglobulin concentration that can be distinguished from zero. It is calculated as the mean plus two standard deviation of 20 replicates of the lowest standard ( 0 mg/L B2M ).
Interference:
Criterion: Recovery within ± 5% of initial value.
No significant interference from bilirubin up to 60 mg/dl; no significant interference from hemoglobin up to 500 mg/dl; no significant interference from lipemia up to 10 g /L of Liposyn, (at which concentration the triglyceride readout is 1376 mg/dl ).
