Calcium CPC - Comprehensive Assessment

OCPC chelate forms purple complex at 575nm quantifying 4.5-13 mg/dL ionized+protein bound calcium across PTH/VitD correlation workflows.

Endocrinology laboratories confirm 8.5-10.5 mg/dL preventing cinacalcet misprescription. Arsenazo alternative eliminates Mg interference.

Quality control verifies chelate specificity, albumin independence, and 24-month stability. Endpoint prevents kinetic artifacts.
