Specimen Specimen Volume (min) Specimen Type Specimen Container Transport Environment
Preferred 1-3mL (0.8mL) See Instructions See Instructions See Instructions
  1. Specimen sites: Nasopharyngeal (NP), Oropharyngeal (OP), Deep Nasal/Mid-turbinate (MT) or Anterior Nares (AN) swab.
    If collecting MT or AN specimens , both nares should be generously sampled with a single swab and placed in a single tube to maximize virus particle collection.
  2. Any swab of appropriate size and configuration with a synthetic or rayon tip and plastic shaft can be used.
  3. Do NOT submit swabs with calcium alginate tips or swabs with wood shafts. All Other Swab types: Suitable for all specimen sites listed, depending on size of swab
    Refrigerate specimens if they will be received in lab within 72 hours of collection.If there will be delayed transport, freeze specimen at -20'C.
  4. Media types: VTM, UTM, M6, or sterile saline (ESwab collection kits should no longer be used for specimen collection for the SARS COV2 PCR assay. 
    The small volume of this collection device can cause technical issues with PCR and precludes any repeat or additional testing. Contact your RML representative for alternate collection devices.)
  5. Swabs must be placed in 1-3 mL of liquid media, broken or cut at the top of the tube, and tubes tightly capped. Specimen tubes should be labeled with two unique patient identifiers. requisition or place electronic order.  Place the tube containing the swab in a biohazard bag and submit with paper requisition.
  6. Please keep specimen refrigerated until pick-up.
  7. Causes for rejection: Swabs with calcium alginate tips; swabs with wooden shafts; refrigerated samples greater than 72 hours old; room temperature swabs greater than 24 hours old; improperly labeled;  grossly contaminated; broken or leaking tube; collection with substances inhibitory to PCR including heparin, hemoglobin, ethanol, EDTA concentrations >0.01M; unacceptable transport media.
  8. Couriers will transport to Regional Medical Core Laboratory. Call RML at 918-744-2232 to request specimen pickup if not routinely scheduled at your location.
Testing Schedule Daily *(see notes section)  
Expected TAT 48-96 hours from receipt of specimen in lab.   
Notes Regional Medical Laboratory continues to be a valuable leader at the forefront of the Coronavirus pandemic, having conducted more than 131,000 SARS-CoV-2 PCR tests over the last 4 months to meet the COVID-19 testing needs of the communities we serve.
