    Abstract:Purpose: To study the influence of the concentration of CaCl2 solution on the determination of heparin sodium potency with sheep blood plasma. Methods: To refer to the method stipulated by USP with 0.50% CaCl2 solution instead of 0.25% CaCl2 solution. Results: The result was consistent with 0.50% CaCl2 solution as well as 0.25% CaCl2 solution. Conclusion: 0.50% CaCl2 solution can substitute for 0.25% CaCl2 solution and has the superiority of reducing the volume of 0.50 clotting.
