Alias Names: BMP
Methodology: Dry Slide Technology
Edit Date: 6/3/2009
Components: Calcium (Ca) / Carbon Dioxide (CO2) / Chloride (Cl) / Creatinine / Glucose / 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 one 4.5 mL plasma separator tube (PST). If a fasting glucose is needed, patient should fast 8-12 hours, otherwise a 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 and PST within two hours of collection and transport in original tube. Centrifuge green top tube within two hours of collection and separate plasma into a plastic tube for transport. Refrigerate.
Stability: 7 days refrigerated.
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.
