Comment: 
  • Tricyclic antidepressants, labetalol and sotalol medications may elevate levels of metanephrines producing results which cannot be interpreted.  If clinically feasible, it is optimal to discontinue these medications at least 1 week before collection.  For advice assessing the risk of removing patients from these medications and alternatives, you may consider consultation with a specialist in endocrinology or hypertension.
  • A single 24- hour urine collection may be used for CATECHOLAMINE FRACTIONATION [CTCH], METANEPHRINES and VMA [VVMA].   
  • The specimen must be kept refrigerated during colleciton.

Comments:

This order is to screen for colonization ONLY.

Enter site of collection in specimen source area.  Make sure collection site is indicated on culturette.

If the provider is checking for infection and wants to treat the patient, see Culture wound other (WND/ABS CLT/GS).

Intended Use:

The intended use of this assay is to screen Mercy Hospital patients for MRSA colonization, by screening nasal and non-infectious wounds, as needed.  The rapid turnaround of results will allow for better patient throughput & bed management (the need or no need to move the patient to isolation) by Mercy staff.  This is in line with Mercy's Service and Stewardship pillars.

Clinics: The wound surveillance assay is not intended for clinic use.  Nasal surveillance assay is the only appropriate assay, in this instance.  Wounds should continue to be ordered as a culture, to look for MRSA.

Hospital reference labs: The wound surveillance assay is not intended for hospital reference lab use, unless a wound surveillance protocol has been established by the reference lab's Infection Prevention Dept., for this type of specimen.

Specimen:  5 ml preservative free random urine in10 mL plastic myoglobin transport tube.
Processing:
  1. If sample is ambient, aliquot the urine to a urine myoglobin transport tube within one hour of collection (Supply T691).  Refrigerate specimen.
  2. If sample is refrigerated, aliquot the urine to a urine myoglobin transport tube within two hours of collection.

    NOTE:  Urinary myoglobin is highly unstable unless alkalinized with Na2CO3 preservative.  Even with alkalinization, myoglobin deterioration is variable and sample dependent (approximately averages of 10% at 1 day, 20 % at 3 days, and 30% at 7 days.  MAYO order code  (MYGLU).
  3. Send refrigerated.
Caution: An elevated level of myoglobin in urine does not identify the clinical disorder.  Urine collected with acid as  preservative will NOT be vailid because acid interferes with analyte integrity.
Performed: 1-2 days.  Test set up Monday through Sunday, continuosly.
Reference value: Included with test results
Method:  Latex Particle-Enhanced Immunoturbidimetric Assay.
