Test ID: VIRNR    
Viral Culture, Non-Respiratory, Varies

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

All routine viral cultures are inoculated into cell culture tubes for viral detection. The most common specimens received for routine testing include body fluid, rectal, spinal fluid, and feces. A rapid (16-hour incubation) shell vial cell culture assay will be inoculated when specimens are designated for herpes simplex virus (HSV), adenovirus(AD) or cytomegalovirus (CMV) detection, or as appropriate for source indicated, and will be charged separately for each virus tested.

 

Information pertaining to specific sources:

Acceptable sources:

-Dermal specimens for enterovirus only (clearly indicate "Enterovirus" on test request)

-Feces- rectal swab (preferred); random fecal specimen (acceptable)

-Brain tissue

-Liver tissue (for CMV and herpes) refrigerated in saline or phosphate buffered saline

-Esophageal tissue, swabs, or brushings

 

Sources not recommended or not acceptable:

-Blood, lymph node tissue, and bone marrow/bone tissue specimens are frequently toxic to cell culture lines. Most molecular methods are appropriate for these specimen types (exception: bone tissue).

-Ocular fluids (vitreous and aqueous): viral culture is not recommended due to usually inadequate volumes. PCR testing is recommended

-Genital, synovial fluid, wound swab or tissue (includes pus, drainage, or abscess fluid)

See Advisory Information for recommended testing on these specimen types.

Advisory Information

Source-based recommendations for testing:

Dermal specimens: Leg, arm, skin, axilla, etc:

Order HERPV / Herpes Simplex Virus 1 and 2, Qualitative PCR, Varies and/or LVZV / Varicella-Zoster Virus, Molecular Detection, PCR, Varies. If a dermal sample is submitted for viral culture, the laboratory will automatically change the testing to HERPV and LVZV.

 

Genital specimens: Cervical, endocervical, genital, labia, penis, perianal, scrotum, vaginal

Order HERPV / Herpes Simplex Virus 1 and 2, Qualitative PCR, Varies. If a genital sample is submitted for viral culture, the laboratory will automatically change the testing to HERPV.

 

Oral specimens: Gum, mouth, palate, tongue, tonsil, parotid, buccal

Order VRESP / Viral Culture, Respiratory

 

Respiratory specimens: Bronchoalveolar lavage, bronchial wash, lung, lung tissue, nasal swab, nasal wash, sputum, throat swab, tracheal aspirate

Order VRESP / Viral Culture, Respiratory

 

Infectious agent-based recommendations for testing:

If cytomegalovirus (CMV) is suspected in bone marrow or urine specimens, order LCMV / Cytomegalovirus (CMV), Molecular Detection, PCR, Varies

 

If herpes simplex virus (HSV) is suspected in a neonatal patient (<1 month), order VHSV / Herpes Simplex Virus (HSV), Culture From Neonates, Varies

 

State Health Department testing only: specimens will not be accepted at Mayo Clinic Laboratories for the following diseases (submit directly to your state health department).

-Measles

-Mumps

-High-risk infectious agents (examples of high-risk infections agents include: Ebola and other causative agents of viral hemorrhagic fever, avian influenza, severe acute respiratory syndrome [SARS], and Middle Eastern respiratory syndrome coronavirus [MERS-CoV])

Shipping Instructions
