Pulsed-Field Gel Electrophoresis




3-10 days

New York DOH Approval Status
This test is New York DOH approved.
Specimen Required
Patient Preparation

Multiple bacterial isolates that are epidemiologically related or are recurrent isolates from the same patient.

Specimen Preparation

Transport individual isolates on agar slants or on swabs in bacterial transport media. Package isolates together in a sealed container.

Storage/Transport Temperature

Room temperature.

Unacceptable Conditions

Mixed cultures or non-viable organisms.


Contact the Microbiology Laboratory at (800) 242-2787, extension 2576, prior to submission of the isolates. Collect multiple bacterial isolates that are epidemiologically related or are recurrent isolates from the same patient. One report will be generated for each batch tested; billing is per isolate. Order one test, using "Infection control, ####" (your ARUP client number) as the patient name. Include a list of isolate identifiers (do not use patient names) on the requisition or as an order note for electronic orders. Identifiers on the requisition must match identifiers on the isolate samples. 


Isolate: Ambient: 1 week; Refrigerated: Unacceptable; Frozen: Unacceptable.
