Important Note

Hemolysis will cause elevated potassium values and minimal volumes will concentrate.

Specimen must be centrifuged within 2 hours of collection or will be rejected.

Additional Codes

N.CMP

Methodology

Automated Chemistry Analyzer (Alinity)

Specimen Requirements

Specimen Type: Serum or Plasma
Container/Tube: SST or Lithium Heparin

Acceptable: Red top
Specimen Volume: 1 mL (minimum 0.5)
Collection Instructions: 

  1. Allow specimen to clot completely if a serum tube (SST) was used.
  2. Separate serum (SST) or plasma (Lithium Heparin) from cells within 24 hours and transport refrigerated. If red top tube is collected, separate serum from cells within 2 hours and place in separate plastic tube.
  3. Properly label tube with patient's name, DOB, requisition number and type of tube, i.e. LiHep or NaHep etc.

Specimen Transport/Stability

Specimen Rejection

  1. Under-filled Tube
  2. Specimen not centrifuged within 2 hours of collection
  3. Unlabeled Specimen
  4. Clotted or Hemolyzed Specimen
  5. Specimen exceeds stability requirements
