Limitations
Heparinized catheters may contain benzalkonium chloride and should not be used for collection due to interference with testing. Do not use specimens obtained through catheters used to infuse hyperalimentation fluid. Blood from patients receiving Hypaque radiographic contrast agent cannot be used due to interference with calcium testing. Do not use blood on patients receiving EDTA therapy. Suramin, an antiparasitic drug, has been reported to cause a bias of -10% in calcium results at a suramin concentration of 300 μg/mL. Calcium results from recumbent patients may be 3% lower. Ammonium ions may cause an increase in measured BUN/UREA value equivalent to the specimen’s nitrogen content. Albumin concentrations vary with posture. Results from an upright posture may be approximately 0.3 g/dL higher than those from a recumbent posture. A delay in centrifugation of several hours can result in a falsely increased potassium result and a falsely decreased glucose result.
Reference Range
See report or individual tests for reference ranges.
Clinical Significance
The Hyperal Panel is a group of tests that are useful in monitoring patients receiving hyperalimentation treatment.
