Test Name:

ADENOVIRUS DNA RAPID PCR, FLUID, RESPIRATORY, TISSUE, STOOL

General Information

Lab Order Codes:

ADVP

Synonyms:

ADV PCR

CPT Codes:

87798 – Infectious agent detection by nucleic acid, not otherwise specified; amplified probe technique, each organism

Test Includes:

Adenovirus detection by PCR. This test does not include adenovirus culture. Refer to Viral Culture.

Logistics

Test Indications:

To detect Adenovirus DNA in clinical specimens.

Human adenoviruses cause a variety of diseases including pneumonia, cystitis, conjunctivitis, diarrhea, hepatitis, myocarditis, and encephalitis. In humans, adenoviruses have been recovered from almost every organ system. Infections can occur at any time of the year and in all age groups. Currently, there are 51 adenovirus serotypes that have been grouped into 6 separate subgenera.

Culture is the gold standard for the diagnosis of adenovirus infection; however, it can take up to 3 weeks to achieve culture results. Serological tests have faster turnaround times, but can be less sensitive compared to culture. PCR offers a rapid, specific, and sensitive means of diagnosis by detecting adenovirus DNA.

Specimen

Specimen Type:

Body Fluid, Respiratory Specimens, CSF, Stool, Swab, Tissue, Urine

Container:

Body Fluid, Respiratory Specimen, CSF, Stool, Tissue, Urine: Screw-capped sterile container
Swab: Culture transport swab (Note: Calcium alginate-tipped swab, wood swab, or transport swab containing gel is not acceptable for PCR testing)

Volume:

Fluid : 0.5 mL fluid (non-centrifuged) (Minimum: 0.3 mL)
Respiratory Specimen, Urine: 1 mL specimen (Minimum: 0.3 mL)
Stool: 1 gm fresh stool (Minimum: 0.5 gm)
Tissue: Fresh tissue in 1-2 mL sterile saline or multi-microbe medium (M5) (Mayo Supply T484)

Collection:

Specimen source is required on all submitted specimens.

Fluid: Collection specific to site
Respiratory Specimen: Bronchial washing, bronchoalveolar lavage, nasopharyngeal aspirate or washing, sputum or tracheal aspirate
Stool: Routine collection
Swab: Collection specific to site. Place swab back into swab cylinder. If a culture transport swab in not available, M4 or M5 media is acceptable.
Tissue: Collection specific to site
Urine: Random Urine collection

Special Processing:

Lab staff:

All specimens: Refrigerated temperatures. Absolute minimum on samples: 0.3 mL

Sample Rejection:

Specimen improperly labeled; QNS; gross contamination. No slides or paraffin blocks will be processed.

Interpretive

Reference Range:

None detected

A positive report indicates the presence of adenovirus. A negative report does not rule out the presence of adenoviruses because organisms may be present at levels below the detection limits of this assay.

Limitations:

  • A negative result does not rule out the presence of PCR inhibitors in the patient specimen or adenoviral nucleic acid in concentrations below the level of detection of the assay.
  • Test results should be used as an aid in diagnosis and should not be considered diagnostic in themselves.

Methodology:

Real-Time Polymerase Chain Reaction (PCR)/DNA probe hybridization
