ELECTROLYTES PANEL (LYTES)

Focused panel that measures the body's core electrolytes, used to screen for and monitor fluid balance, acid-base status, and conditions like dehydration or kidney and adrenal disorders.

LIS PANEL CODE: (MID) Electrolytes Panel (LYTES)

INDIVIDUAL LIS TEST CODES INCLUDED WITHIN PANEL: CO2, K, NA, CL, AGP

CPT CODE: 80051

ALIASES: LYTES, Lytes Panel, Electrolytes

METHODOLOGIES: Spectrophotometry, Ion-Selective Electrode (ISE)

SPECIMEN:

- Type: Serum

- Container: Gold Top (SST) Vacutainer

- Minimum Volume Required: 1 mL

- Storage/Handling: Allow 30 minutes for blood to clot, then centrifuge specimen at 3500 RPM for 10 minutes. Maintain specimen at room temperature or in the refrigerator until testing can be performed.

- Stability:

Room Temperature (20-25 °C): 2 hours

Refrigerated (2-8 °C): 3 days

Frozen (-20 °C or colder): Not Accepted

- Turnaround Time: 24 hours from receipt.

Special Instructions: Avoid prolonged tourniquet time and fist-clenching, which can falsely elevate potassium.
