Aiding in the diagnosis of adenovirus infections

Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

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 over 50 adenovirus serotypes that have been grouped into 6 separate subgenera.


Although adenovirus can be recovered in cell culture, it can take up to 3 weeks for the virus to be identified by culture methods (Mayo Clinic's shell vial culture provides more rapid results, reported at 2 and 5 days). Serological tests have faster turnaround times but can be less sensitive compared to culture. Polymerase chain reaction assays offer a rapid, specific, and sensitive means of diagnosis by detecting adenovirus DNA.

Reference Values
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.


Provides information to assist in interpretation of the test results

A positive result indicates the presence of adenovirus DNA in the clinical specimen.


A negative result does not rule out the presence of adenovirus because viral DNA may be present at levels below the detection limits of this assay.

Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

Test results should be used as an aid in diagnosis and should not be considered diagnostic in themselves.


Although the reference range is generally considered to be "Negative" for this assay, adenovirus DNA may be detected from asymptomatic individuals in certain settings. This assay should only be used to test patients with clinical history and symptoms consistent with adenovirus disease, and is not used to screen healthy patients.   

Supportive Data

The following support the use of this assay for clinical testing.


Accuracy/Diagnostic Sensitivity and Specificity:

A study of 715 clinical specimens compared shell vial culture and this polymerase chain reaction (PCR) assay. Included in the study were 288 swab specimens (nasal, throat, rectal, skin), 125 eye specimens, 221 respiratory specimens (bronchial washings, sputa, bronchioalveolar lavage, tracheal secretions), 56 fresh tissue specimens, 72 stools, 5 urines, and 27 body fluids/other specimens. Specimens were inoculated into culture tubes and examined for cytopathic effects over a period of 14 days, and subsequently assayed with this LightCycler (LC) assay. Comparison of cell culture with LC PCR yielded the following: total specimens positive by LC PCR was 83 (stool=7; respiratory=8; tissue=3; swabs=29; eye specimens=30; miscellaneous= 1 and urine=4) and total specimens positive  by culture were 76 (stool=6; respiratory=7; tissue=3; respiratory swabs=28; eye specimens=29; and urine=2, miscellaneous = 1). Of the 83 total positive specimens, PCR detected ~10% more adenovirus infections compared with culture. This assay detected all 57 serotypes of adenovirus tested.


Supplemental Data (Spiking Studies):

To supplement the above data, 30 negative specimens of various types (spinal fluid, ocular, respiratory, stool, urine, and plasma) were spiked with adenovirus positive control plasmid at the limit of detection (approximately 10 targets/microliter). The 30 spiked specimens were run in a blinded manner with 30 negative (non-spiked) specimens. One hundred percent of the spiked specimens were positive, and 100% of the non-spiked specimens were negative.


Analytical Sensitivity/Limit of Detection:

The limit of detection for this assay is 10 targets per microliter in specimen matrix.


Analytical Specificity:

No PCR signal was obtained from extracts of 150 bacterial, viral, parasitic, and fungal isolates that could cause similar disease or could be found as normal flora in sites normally tested for this organism.



Interassay precision was 100% and intra-assay precision was 100%.


Reportable Range:

This is a qualitative assay and results are reported as negative or positive for targeted adenovirus DNA.

Method Description
Describes how the test is performed and provides a method-specific reference

Respiratory, swabs, stools, tissues, plasma, and urine samples are processed according to specimen source. Viral nucleic acid is extracted by the MagNA Pure automated instrument (Roche Applied Science). Primers and fluorescence resonance energy transfer (FRET) probes target a relatively conserved 185 base-pair region of the adenovirus penton gene. The LightCycler instrument (Roche Applied Science) amplifies and monitors the development of target nucleic acid sequences after the annealing step during polymerase chain reaction (PCR) cycling. This automated PCR system rapidly detects amplicon development through stringent air-controlled temperature cycling in capillary cuvettes. The detection of amplified products is based on the FRET principle. For FRET product detection, a hybridization probe with a donor fluorophore, fluorescein, on the 3'-end is excited by an external light source and emits light that is absorbed by a second hybridization probe with an acceptor fluorophore, LC-Red 640, at the 5'-end. The acceptor fluorophore then emits a light of a different wavelength that can be measured with a signal that is proportional to the amount of specific PCR product.(Unpublished Mayo method)
