30000:COMPREHENSIVE METABOLIC PANEL (CMP)
Alias Names:	CMP / Chem Screen / Comp metabolic panel
Methodology:	Indirect Potentiometry / Colorimetry / Enzymatic Rate
Edit Date:	7/15/2009
Components:	Alanine Aminotransferase (ALT) / Albumin / Alkaline Phosphatase / Aspartate Aminotransferase (AST) / Bilirubin, Total / Calcium (Ca) / Carbon Dioxide (CO₂) / Chloride (Cl) / Creatinine / Globulin /Glucose / Potassium (K) / Protein, Total / Sodium (Na) / Urea Nitrogen (BUN)
Performed:	Daily
Released:	Same day
CPT Code:	80053
Specimen Collection Details
Collection:	One 7.5 mL serum separator tube (SST). Also acceptable: One 4 mL green top tube (heparin) or one 4.5 mL light green plasma separator tube (PST). Preferred specimen is from patient fasting 8-12 hours; non-fasting specimen is acceptable. Do not draw from a limb receiving an intravenous insfusion. Patient should avoid exercising forearm before collection, which can cause an increase in potassium level.
Handling:	Centrifuge SST or PST within 2 hours of collection and transport in original tube. Centrifuge green top tube within 2 hours of collection and separate plasma into a plastic tube for transport. Refrigerate.
Stability:	6 days refrigerated.
Standard Volume:	2 mL serum or plasma.
Minimum Volume:	1 mL serum or plasma.
Transport:	Refrigerated.
Rejection Criteria:	Gross hemolysis; specimen left in contact with cells for more than 3 hours; tubes other than those specified.
