Test Code BMP.1 BASIC METABOLIC PANEL (BMP), TOTAL CA

Important Note

Hemolysis will cause elevated potassium values and minimal volumes will concentrate

Whole blood green top Lithium heparin can be run on alternate Chemistry Analyzer which includes Chem B with Ionized Calcium, this specimen must reach lab within 10 minutes.

Specimen must be centrifuged within 2 hours of collection or will be rejected.
