Test Code RENAL.1 RENAL FUNCTION PANEL

Important Note

Avoid hemolysis. Hemolysis will cause elevated potassium and minimal volumes will concentrate.

Automated Chemistry Analyzer

Serum or Plasma

Container: SST tube or Green top Lithium heparin

Specimen Collection: 1 mL (minimum 0.5 mL)

Allow specimen to clot completely if a serum tube (SST) was used.
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.
Properly label tube with patient's name, DOB, requisition number and type of tube, i.e. GREEN.

Refrigerated: 24 hours on gel, 7 days poured off

1. EDTA, sodium citrate or sodium fluoride-oxalate plasma specimen

2. Under-filled Tube
