31300:BASIC METABOLIC PANEL
Alias Names: BMP / Basic Eval PNL / Mini Screen
Methodology: Colorimetry / Indirect ISE and Kinetic Rate
Edit Date: 6/3/2009
Components: Calcium (Ca) / Carbon Dioxide (CO2) / Chloride (Cl) / Creatinine / Glucose / Glomerular Filtration Rage (GFR) / Potassium (K) / Sodium (Na) / Urea Nitrogen (BUN)
Performed: Daily
Released: Same day as tested
CPT Code: 80048
Specimen Collection Details
Collection: One 7.5 mL serum separator tube (SST). Also acceptable: One 4 mL green top tube (heparin) or 4.5 light green top 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 infusion. Patient should avoid exercising forearm before collection, which can cause an elevation in the potassium level.
Handling: Allow to clot, centrifuge SST or PST within two 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. Freeze if specimen will not reach lab within 6 days of collection.
Stability: 6 days refrigerated or 1 month frozen..
Standard Volume: 2 mL serum or plasma.
Minimum Volume: 0.5 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.
