Test Code KPNL Basic Metabolic Panel, Plasma

Important Note

Note: For chronic lymphocytic leukemia (CLL)  patients with WBC count >100,000, the specimen should be collected in a Gold SST  for the Basic Metabolic Panel. Order code SSTKP in EPIC.

Specimen Type

Preferred: Plasma

Acceptable: Serum


Preferred: Lithium Heparin (Mint Green or Dark Green)

Acceptable: Serum Red Top tube or Gold SST


*Note: If ordering SSTKP collect using Gold Top Tube

Preferred Volume

5 mL

Offsite Collection Instructions

1. Serum and plasma tubes should be centrifuged and aliquoted within 2 hours of collection.

2. Aliquoted samples could either be room temperature at 15-25°C or refrigerated at 2-8°C prior and during transportation.

3. If above criteria are not met, specimen will be rejected.

UCMC Collection Instructions

1. Samples need to be received in the lab within 2 hours of collection at room temperature.

2. Greater than 2 hours must be refrigerated at 2-8°C.

3. If the specimen cannot be sent to the lab within 6 hours of collection, it must be spun, aliquoted and refrigerated at 2-8°C.

4. All unspun specimens greater than 6 hours will be rejected.  

5. If above criteria are not met, specimen will be rejected.



Turnaround Time

Test Methodology

Spectrophotometric and ion-specific electrode

Additional Information

Refer to entries for individual analytes. Refer to creatinine listing for additional information regarding the calculated GFR.

CPT Code


Reference Range

Refer to Individual Analytes.
Refer to creatinine for calculated GFR reference range.
The anion gap will be calculated as [Na] – [Cl + HCO3]. The reference range for this calculated result is 6 – 15 mEq/L.

Coverage Information

Each of these may be ordered individually. A test or panel may be ordered only when all components are medically necessary to diagnose or treat an individual patient. If all components are not medically necessary, a less inclusive panel and/or an individual test as appropriate to treat the individual patient should be ordered.
