Blood Sodium Content Assay kit

Serum sodium plays an important role in maintaining normal extracellular fluid volume and osmotic pressure, as well as the acid-base balance of body fluids. The sodium and potassium pyroantimonate reagent in the serum form a precipitate in the weakly alkaline solution. The amount of the precipitate is proportional to the sodium concentration. The turbidity can be used to determine the serum sodium content.
