Clinical Chemistry Total Proteins (Serum or Plasma) Direct colorimetric determination of total protein in serum or plasma. Total protein determination has a broad application in diagnostics, indicating general states such as malnutrition and dehydration. n Single liquid-stable reagent n Linearity: up to 10 g/dL n Open-vial stability: 90 days when stored at 2-8C n Includes standard Sodium Pricing and Online Ordering at www.alphalabs.co.uk n freephone order 0800 387732 n buy online at www.alphalabs.co.uk 246 Technical information: In alkaline solution, proteins combine with copper ions to form a coloured complex, the intensity of which is proportional to the amount of total protein in the sample.

Sodium is part of the basic metabolic panel and is used to detect abnormal concentrations; low blood sodium is termed hyponatremia whilst excessive sodium is hypernatremia. Hyponatremia is typically the result of sodium loss which can occur in conditions such as Addison’s disease, diarrhoea, diuretic use or kidney disease. It may also arise due to water retention when too much anti-diuretic hormone is produced or excessive fluid accumulation as can occur in heart failure or cirrhosis patients. Hypernatremia is usually the result of inadequate water intake and dehydration but can also be caused in rare cases by Cushing syndrome or diabetes insipidus. n Enzymatic photometric method n Dual, ready-to-use reagent system n Linearity up to 180.0 mmol/L Technical information: Sodium is determined enzymatically via sodium-dependent β–galactosidase activity using o-Nitrophenyl-β-D-glycodise as substrate. The absorbance at 405nm of the product o-nitrophenyl is proportional to the sodium concentration.

Transferrin is the main protein in the blood that binds and transports iron. Transferrin tests are often requested alongside iron and ferritin to evaluate a patient’s iron status, in cases of iron deficiency the transferrin concentration may rise and conversely a fall may be seen in patients with iron overload. Transferrin is produced in the liver and low levels are also seen in patients with liver disease. n Ready to use reagents n Range 0-500 mg/dL Technical information: This turbidimetric method is based on the formation of insoluble antigen-antibody complexes between transferrin in the patient sample and the goat anti-transferrin antibody in the reagent. Inclusion of polyethylene glycol in the reagent accelerates and enhances the complex formation which leads to the increase in turbidity of the test solution.
