Please forward all requests to Microbiology.


This test is helpful in diagnosis of culture negative infections. Tissue collected by surgical excision, normally sterile fluid, BAL, or abscess drainage material (when collected under sterile conditions) can be submitted for detection of bacteria by molecular methods. For in-house patients, a bacterial culture of the same sample must be submitted and confirmed as No Growth before the PCR testing will proceed. If a particular pathogen is suspected this information should be included in the Ordering comments. With bacterial growth, PCR testing will be cancelled. Consult with the Microbiology Director if PCR testing is still necessary.


For Cerebrospinal Fluids (CSF) PCR, see CSF Bacterial PCR.


External/Non-Children's ordering physicians must consult the Microbiology Director prior to sending any sample to Children's Microbiology Laboratory for PCR testing. 

Sample Requirements

Specimen: Tissue, Normally Sterile Fluid, BAL, or Abscess material

Container: Sterile Container

Preferred Vol: 1.0mL or grams

Minimum Vol: 0.5mL or grams


Swabs are not accetable and will be rejected. 


Processing Instructions

CPA: Send all samples to Microbiology for processing. If sample is shared and only one tube, syringe or other container is received, affix shared sample label and send entire sample plus requisition to Microbiology.


Off-site collection:  Off-site Children's Lab locations should send to SCH Main Campus for testing. If the sample has additional testing ordered, see the respective procedure for the appropriate storage and transport conditions.


For other off-site locations, sample should be stored frozen at -20C prior to and during transport to the SCH Microbiology Laboratory.
