What is potassium oxalate primarily used for?

• A. Enhancing glycolysis
• B. Binding calcium
• C. Inhibiting glucose breakdown
• D. Preventing blood coagulation

Answer: (B)

Potassium oxalate is primarily used for preventing blood coagulation. In the context of blood collection and laboratory testing, potassium oxalate serves as an anticoagulant that binds calcium ions in the blood. The binding of calcium is crucial because calcium plays an essential role in the coagulation cascade, activating various clotting factors that lead to the formation of a clot. By effectively chelating calcium, potassium oxalate helps ensure that the blood remains in a liquid state, which is vital for accurate laboratory analysis and diagnostic testing. The use of potassium oxalate is particularly important in situations where the preservation of blood components is needed for testing, such as in certain biochemical assays. Its role in preventing coagulation is critical for obtaining reliable results from samples that need to be analyzed without the interference of clot formation.
