Special Quality Controls
BIOMED’s special quality controls include accuracy control sera for quality control in the analysis of blood concentrations of alcohol, ammonia, cystatin C, bilirubin and various heart markers.
Alcohol-Ammonia Controls
The stable, human serum matrix based liquid control Duotrol®Alcohol/Ammonia Combi is designed to monitor quantitative analytical conditions for the determination of alcohol and ammonia in human serum and plasma samples in clinical laboratories.
Bilirubin Controls
Duotrol®Bilirubin Paediatric is a stable bovine serum-based liquid control for the quantitative determination of bilirubin in the high, abnormal range and is used to monitor assay conditions in clinical laboratory testing of serum and plasma samples. The analyte concentrations are achieved with bilirubin extracts and synthetic derivatives.
Bilirubin in serum is composed of unconjugated, conjugated and δ bilirubin. Endogenously, 80 – 85 % bilirubin is produced daily. Elevated bilirubin levels are associated with Meulengracht’s disease, hepatitis, fatty liver or liver cirrhosis, bile congestion and hemolysis.
Cystatin C-controls
Duotrol® Cystatin C is a liquid correctness control serum of human origin with target values in the normal and pathological range.
Cystatin-C is produced endogenously at a constant rate by almost all nuclear cells in the human body. The serum concentration depends on the glomerular filtration capacity of the kidney. With a reduced GFR the concentration of cystatin C increases. Cystatin C concentration is not influenced by age, sex, muscle mass, nutrition and inflammatory processes (except immune diseases). Cystatin C is elevated in renal insufficiency and autoimmune diseases.
