Laboratory Lab results are too important to go anywhere else.

ICU Panel

ICU Panel (Inpatients Only)

Test Codes

EPIC: LAB5073, ICU

Department

Chemistry

Instructions

• This test is only available for order on inpatients.
• Blood should be obtained with as little venous stasis (i.e., tourniquet time) as possible. Fist clenching may result in false elevation of potassium and calcium.
• Specimen should be kept tightly closed since CO₂ will diffuse out if the tube is uncapped. This will cause an erroneously decreased value.

Specimen Collection Criteria

FOR EC AND INPATIENT SAMPLE COLLECTION ONLY:

Preferred Sample:  One Light Green Top Plasma Separator Tube (PST)(Minimum Whole Blood: 4.0 mL)

Acceptable Sample:  One Gold Top SST (Minimum Whole Blood:  4.0 mL)

FOR PHYSICIAN OFFICE/OUTREACH SAMPLE COLLECTION:

COLLECT:  One Gold Top SST (Minimum Whole Blood:  4.0 mL) 

Contact Laboratory for acceptability of other tube types.
See Minimum Pediatric Specimen Requirements for Microtainer^® collection.
Caution: Never refrigerate collection tube prior to centrifugation. This may cause a falsely elevated potassium.

Rejection Criteria

• Moderate to grossly hemolyzed specimens.
• Red-top tubes with serum not separated from cells within two hours of collection.

In-Lab Processing

Let SST specimens clot 30-60 minutes. Centrifuge SST tubes or Microtainers^® to separate serum from cells. Deliver immediately to the appropriate testing station.

Storage

Specimen Stability for Testing:

*Carbon Dioxide (CO₂) has a stability of 3 days refrigerated. Phosphorus has a stability of 4 days refrigerated at Grosse Pointe, and Total Bilirubin has a stability of 5 days refrigerated at Grosse Pointe. CO₂ will not be reported for ICU Panel add-on requests on specimens greater than 72 hours past the time of collection.
