Clinical Biochemistry

Clinical Biochemistry is the division of laboratory medicine that deals with the measurement of chemicals in blood, urine and other body fluids. These test results are useful for detecting health problems, determining prognosis and guiding the therapy of a patient.

Our Clinical Biochemistry Devices and equipment

The cobas c 501 module is a mid volume analyzer comprised of a photometric unit for a broad range of clinical chemistry assays and an ISE unit for ion-selective electrode determinations of sodium, potassium, and chloride in serum, plasma, or urine. 

This module is also capable of measuring HbA1c levels in whole blood, making it a truly flexible and versatile analyzer.

The BN ProSpec® is a dedicated, compact system that offers a consolidated menu of specialty and routine reagents for reliable plasma protein testing including cardiac risk assessment, kidney diseases, nutritional assessment and iron and anemia assessment as well as innovative markers such as monoclonal kappa and lambda free light chains, Cystatin C and Carbohydrate-Deficient Transferrin (CDT).

  • Ideal for low- to mid-volume plasma protein throughput
  • Comprehensive menu from one source: Over 64 assay protocols available for determination of various sample types
  • Optimal alignment of systems and reagents
  • Refrigerated onboard storage of controls and reagents
  • Assistance with clinical interpretation through our innovative range of assessment programs available for Protis® Data Management System.

The 797 VA Computrace is a modern voltammetric measuring stand. The computer software provided controls the measurement, records the measured data and evaluates it. Operation is most straightforward due to the well-laid-out structure of the program. The integrated potentiostat with galvanostat guarantees the highest sensitivity with reduced noise.

Voltammetry system for trace analysis and education. Complete accessories with VA Computrace software and all electrodes for a complete measurement system: Multi-Mode Electrode pro (MME pro), Ag/AgCl reference electrode and Pt auxiliary electrode.

Specimen: Serum, Urine, 24 Hour Urine, Body Fluid, 

Specimen Stability: 7 days at 15‑25 °C
1 month at 2‑8 °C

Special Instructions: Collect urine without additives. α‑Amylase is unstable in acid urine.
Assay promptly or adjust pH to alkaline range (just above pH 7) before storage.

Principle and method: Enzymatic colorimetric assay

Specimen Volume: 1 mL

Device: Roche Cobas C 501

Limitation: Highly turbid and grossly lipemic samples may cause Abs. flags.
Anticoagulants: Interference was found with citrate, fluoride, and EDTA.
Exception: Icodextrin‑based drugs may lead to decreased amylase results.

Turnaround Time (TAT): Daily 

Department: Clinical Biochemistry

The ACCR is calculated from amylase activity and creatinine concentration.
Both the serum and urine samples should be collected at the same time.
