CATECHOLAMINES,PL [EP/NOR/DOP]

LAB963

Collect

Green (sodium or lithium heparin). Collect on ice.

Patient Preparation

Patient should be calm and supine for 30 minutes prior to collection.

Specimen Preparation

Specimen should be centrifuged and frozen within one hour (refrigerated centrifuge is preferred but not required). Transfer 4 mL plasma to an ARUP Standard Transport
Tube. (Min: 2.1 mL)

Unacceptable Conditions

EDTA plasma, serum, or urine.

Storage/Transport Temperature

Plain green and PST are both acceptable.

Stability (from collection to initiation)

After separation from cells: Ambient: Unacceptable; Refrigerated: Unacceptable; Frozen at -20°C: 1 month; Frozen at -70°C: 1 year

Notes

Medications that may interfere with catecholamines and metabolites include amphetamines and amphetamine-like compounds, appetite suppressants, bromocriptine, buspirone, caffeine, carbidopa-levodopa (Sinemet), clonidine, dexamethasone, diuretics (in doses sufficient to deplete sodium), ethanol, isoproterenol, labetalol, methyldopa (Aldomet), MAO inhibitors, nicotine, nose drops, propafenone (Rythmol), reserpine, theophylline, tricyclic antidepressants, and vasodilators. The effect of drugs on catecholamine results may not be predictable. 

For optimum results, patient should be supine for 30 minutes prior to collection.

Children, particularly those under 2 years of age, often show an elevated catecholamine response to stress.

Ordering Recommendations

Not recommended for evaluation of pheochromocytoma or paraganglioma. Use to evaluate clinical symptoms of excess catecholamine secretion. For the assessment of pheochromocytoma and paraganglioma, refer to Metanephrines, Plasma (Free) (0050184) or Metanephrines Fractionated by HPLC-MS/MS, Urine (2007996).

Dopamine2 days and older: 0-20 pg/mL

Interpretive Data

Small increases in catecholamines (less than 2 times the upper reference limit) usually are the result of physiological stimuli, drugs, or improper specimen collection.  Significant elevation of one or more catecholamines (2 or more times the upper reference limit) is associated with an increased
probability of a neuroendocrine tumor. Measurement of plasma or urine fractionated metanephrines provides better diagnostic sensitivity than measurement of catecholamines.  

Higher catecholamine concentrations are observed in specimens collected from upright or standing adults.  Epinephrine may be increased by approximately 20 percent; norepinephrine up to 700 pg/mL; dopamine, unchanged.

CDIFFICILE TOXIN PCR

LAB3716
CDIFTOXPCR

Collect

500 uL of unformed or semi-formed stool in a sterile container with no preservatives or additives.

Pediatric Collection

Test is not performed for patients less than 2 years of age. For patients older than 2 years, the minimum testing volume is 100 uL of fresh, unformed stool.

Unacceptable Conditions

Sample not properly identified; incorrect container; insufficient sample volume; samples with preservatives; formed samples; multiple samples received in a 7 day period.

Storage/Transport Temperature

Internal: Deliver to lab immediately at ambient temperature. If delivery is not expected to occur within 2 hours,  refrigerate and deliver on a cold pack.

Offsite: Keep refrigerated and deliver to lab immediately on cold pack. Refrigerated sample must be received within 5 days of collection. Frozen samples are acceptable, but fresh is preferred.

Stability (from collection to initiation)

Ambient: 24 hours; Refrigerated: 5 days.

Remarks

The results of this test should be coupled with clinical indicators for diagnosis, as Toxin B may be detected for an extended period after successful treatment. A negative CDIFTOXPCR result does not excludeC. difficile involvement in a disease process.

Performed by

PCL Clinical Laboratory - Molecular Diagnostics and Virology Departments

Notes

This assay will identify non-027/NAP/BI isolates representing toxinotype XIV and occasionally toxinotypes IV, V and X as presumptive positives for 027/NAP/BI.

Vagisil cream and zinc oxide paste are potential interfering substances.

Performed

Daily, 7:00 AM to 10:00 PM

 

Methodology
