VANCOMYCIN TROUGH

LAB39

VANC T

Collect

One 4.5 mL Green top with gel (PST), plasma (lithium heparin).

 

Pediatric Collection

At least 0.5 mL whole blood collected in a microtainer, green top with gel, lithium heparin plasma.

Unacceptable Conditions

Sample not properly identified; incorrect container; insufficient sample volume.

Storage/Transport Temperature

Internal: Deliver to lab immediately at ambient temperature.
Offsite: Centrifuge within 30 minutes of collection. Transport to laboratory at 2-8 degrees C.

Stability (from collection to initiation)

Before centrifugation: Ambient, 1 hour.

After centrifugation: Ambient, 8 hours; Refrigerated, 48 hours; Frozen, Unacceptable.

Plasma aliquot: Ambient, 8 hours; Refrigeratd, 48 hours; Frozen (-20 degrees C), Greater than 48 hours.

Remarks

Include dosage information. Trough levels should be drawn immediately before next dose. Random levels are not necessary for patients wiith normal renal function and appropriate peak levels.

Interpretive Data

Trough vancomycin serum concentrations of >= 10.0 μg/mL usually ensure that the concentration is above the minimum inhibitory concentrations of most vancomycin-sensitive pathogens. Trough concentrations above 20.0 μg/mL are associated with nephrotoxicity.   For effective treatment, some patients may require serum or plasma levels outside these ranges.  Therefore,  the  expected  ranges  are  provided  only  as  general guidance,  and  individual  patient  results should be interpreted in light of clinical signs and symptoms.
