A Multi-Site Clinical Evaluation of the LIAISON NES FLU A/B, RSV & COVID-19 Assay in Symptomatic Patients
(NES ABCR)
What this study is about
The DiaSorin Molecular LIAISON® NES FLU A/B, RSV \& COVID-19 real-time polymerase chain reaction (RT-PCR) assay is intended for use on the DiaSorin LIAISON® NES instrument for the in-vitro qualitative detection and differentiation of nucleic acid from influenza A, influenza B, RSV and SARS-CoV-2 virus from dry nasal swabs (NS) from human patients with signs and symptoms during the acute phase of respiratory tract infection in conjunction with clinical and epidemiological risk factors. The LIAISON® NES FLU A/B, RSV \& COVID-19 assay is intended for use as an aid in the differential diagnosis of influenza A, influenza B, RSV and SARS-CoV-2 infection in a professional laboratory setting. Negative results do not preclude influenza A, influenza B, RSV or SARS-CoV-2, infection and should not be used as the sole basis for patient management decisions. The assay is not intended to detect the presence of the influenza C virus.

DIAGNOSTIC_TEST
LIAISON NES FLU A/B, RSV & COVID-19
The LIAISON® NES FLU A/B, RSV \& COVID-19 assay used on the LIAISON® NES instrument is a real-time PCR system that enables the direct amplification, detection and differentiation of Flu A viral RNA, Flu B viral RNA RSV viral RNA, and SARS-CoV-2 RNA from dry nasal swabs. Nasal Swabs can be professionally collected by a Healthcare Provider or self-collected by the patient under the supervision of the healthcare provider. The collected nasal swab can then be directly loaded into the cartridge without nucleic acid extraction.
Primary outcome measures
Diagnostic Accuracy
Time frame: Samples will be tested on LIAISON NES within two hours of collection.
Estimates of Sensitivity/percent positive agreement (PPA) and Specificity/percent negative agreement (NPA) will be calculated based on a two-by-two table (comparator method result vs. result from LIAISON® NES FLU A/B, RSV \& COVID-19 assay or LIAISON PLEX® RSP Flex assay) for each target. In addition, 95% two-sided confidence intervals will be provided. A separate Sensitivity/PPA and Specificity/NPA for each target, to include those specimens excluded due to a discrepancy between the standard-of-care and molecular comparator result, will be presented in a separate 2 x 2 table.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- The specimen is a NPS or NS from a patient collected and preserved in 3 mL Universal Transport Media (UTM), BD Universal Viral Transport (UVT), or MicroTest M4RT transport media, or 1 mL Copan Eswab (Liquid Amies).
- The specimen is from a patient 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 human patient with active signs and symptoms of respiratory tract infection at time of collection
- Specimen stored at 2-8°C for up to 72 hours from collection. If there is a delay in testing, store specimen at ≤-70 °C.
- The total volume of the leftover specimen received is ≥1.5 mL, except for specimens collected in Liquid Amies which requires a total leftover volume of ≥0.5 mL
- The specimen was received in good condition (no leakage or drying of the specimen).
Exclusion criteria
- Incorrect swab type
- Incorrect transport media
- Incorrect specimen handling (e.g. specimens not stored at recommended temperature)
- The specimen has undergone more than two freeze/thaw cycles
- Specimens collected with calcium alginate or organic swabs
Where
- Henderson, Nevada
- Pittsburgh, Pennsylvania
- McAllen, Texas

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
