ELY
  
Lytes
  
  • Sodium (Na),
  • Potassium (K),
  • Chloride (Cl)
  • Carbon dioxide (CO2)

Specimen

  
Lithium heparin (Li hep) plasma
  
  
1.0 mL
  
0.3 mL
  

If the patient has a white blood cell (WBC) count of >50,000, for chemistry testing that includes potassium, the sample should be collected in a gold serum separator (SST) tube and not a Lt green plasma separator (PST) tube.

Immediately follow collection, mix sample by inverting 8 - 10 times to prevent clotting

  

Spin

  

Plasma separator (Lt green PST)

  
Serum
  

Immediatley following collection, mix sample by inverting 5 times

  

Gold:

  1. Allow sample to clot for a minimum of 30 minutes
  2. Spin within two (2) hours of sample collection

Red:

  1. Allow sample to clot
  2. Spin
  3. Transfer serum to a False bottom plasma/serum transport vial/tube (AHL), labelled as serum, within two (2) hours of sample collection
  
  

Refrigerated (preferred) - 7 days

Ambient - 7 days
