A Two Arm, Multi-Centre Clinical Evaluation of the NxTAG Respiratory Pathogen Panel

This study has been completed.
Information provided by (Responsible Party):
Luminex Molecular Diagnostics Identifier:
First received: February 1, 2013
Last updated: March 1, 2016
Last verified: March 2016

xTAG RPP assay is a PCR-based assay to detect the presence or absence of viral and bacterial DNA / RNA in clinical specimens (nasopharyngeal swabs).

The objective of this study is to establish diagnostic accuracy of the xTAG RPP.

Condition Intervention
Respiratory Tract Infection Bronchitis Bronchiolitis Pneumonia Device: xTAG RPP

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Official Title: A Two Arm, Multi-Centre Clinical Evaluation of the NxTAG Respiratory Pathogen Panel (NxTAG RPP) in Patients With Clinical Signs and Symptoms of Respiratory Tract Infection

Further study details as provided by Luminex Molecular Diagnostics:

Primary Outcome Measures:
  • Diagnostic accuracy will be expressed in terms of clinical sensitivity and specificity for each claimed target. [ Time Frame: Within the first year after sample extraction ]
    Accuracy determinations (diagnostic sensitivity and specificity, positive and negative agreement) were based on the fraction of comparator positive (or negative) results which were also positive (or negative) by xTAG RPP.

Biospecimen Retention:   Samples With DNA
Nasopharyngeal swab

Enrollment: 1500
Study Start Date: January 2015
Primary Completion Date: September 2015 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Blinded, Pre-selected Arm
For targets that exhibit lower prevalence rates in the intended use population, banked, pre-selected, positive clinical specimens will be tested.
Device: xTAG RPP
Blinded, Prospective Arm
Diagnostic accuracy for the more prevalent targets will be evaluated in prospectively collected, de-identified, left-over, clinical specimens accrued during the 2012/2013 flu season.
Device: xTAG RPP


Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
Clinical specimens collected from patients with clinical signs and symptoms of respiratory tract infection who are either hospitalized, admitted to emergency departments or visiting outpatient clinics.

Inclusion Criteria:

  • The specimen is a nasopharyngeal swab.
  • The specimen is from a pediatric or adult, male or female subject who is either hospitalized, admitted to a hospital emergency department, visiting an outpatient clinic or resident of a long-term care facility.
  • The specimen is from a patient exhibiting clinical signs and symptoms of respiratory tract infection such as fever, sore throat, shortness of breath, bronchitis, bronchiolitis and pneumonia.

Exclusion Criteria:

  • The specimen is not a nasopharyngeal swab.
  • The specimen is from an individual who does not exhibit clinical signs and symptoms of respiratory tract infection.
