👉 The ONS Fluid, also known as Ons Fluid, is a synthetic, non-ionic, water-soluble, and non-toxic solution used as a reference standard for measuring the concentration of various substances in biological fluids. It's composed of a mixture of sodium chloride, magnesium sulfate, and potassium chloride, which mimic the ionic environment of blood plasma. This standardization is crucial for accurate biochemical and clinical diagnostics, enabling precise quantification of analytes like glucose, electrolytes, and drugs in patient samples. Its stability, purity, and consistent composition make it an invaluable tool for laboratories worldwide.
