|Methodology||Enzymatic, Colorimetric (LOX/PAP)|
|Description||Useful for the evaluation of clinical conditions related to tissue hypoxia; diabetes mellitus and metabolic acidosis.
NOTE: Acetaminophen concentrations at toxic levels and high doses of N-Acetylcysteine (NAC) used to treat acetaminophen intoxication can falsely lower the result of this test. N-Acetylcysteine used as mucolytic will not influence the result of this test.
|Specimen||DO NOT USE A TOURNIQUET DURING COLLECTION.
Draw blood in a grey-top (sodium fluoride/potassium oxalate) tube. Place whole blood on ice, spin down and separate plasma from cells within 15 minutes of draw and refrigerate immediately. Send 1.0 mL of sodium fluoride/potassium oxalate plasma refrigerated.
Stability (if separated from cells):
Refrigerated or on ice - 14 days
Room temperature - 8 hours
|Reference Values||0.5 - 2.0 mmol/L
Critical Value: > or = 4.0 mmol/L
