Container:Green top with gel (PST) (lithium heparin); Red w/gel (tiger top) or Gold SST; Pediatric PST (green top) or SST (gold top); Red top w/out gel
Minimum volume: 0.2 mL plasma/serum
Fill tubes completely. CO2 decreases of up to 3 mmol/L can be observed with partially filled tubes.
Blood collected during prolonged tourniquet use may have calcium concentrations 15% higher.
Specimen Preparation
Centrifuge specimens and remove the serum or plasma from the cellular material within 4 hours of collection.
Pediatric Collection
Container: Pediatric PST (green top) or SST (gold top)
Minimum volume: 0.5 mL whole blood
Unacceptable Conditions
Any hemolysis
Incorrect container
Sample not properly identified
Insufficient sample volume
Storage/Transport Temperature
Internal: Deliver to lab immediately. Offsite: Centrifuge within 30 minutes of collection and transport to lab at 2-8°C.
Stability (from collection to initiation)
Room Temperature: 4 hours Refrigerated: 3 days Frozen: 1 month
Performed
Upon receipt
Remarks
Hemolyzed samples will cause a false elvation in potassium values. Lysis of only 0.5% of the erythrocytes can increase potassium levels by 0.5 mmol/L. In samples with gross hemolysis the potassium results may not be reported.
