An Easier, more comfortable
way to swab
Rhinoswab is a patented comfortable, self-administered nasal swab that provides high-yield sampling and fits existing pathology workflows.
In response to the COVID-19 pandemic, Rhinomed applied its deep expertise in nasal airway technology to help address the global swab supply shortage.
Through innovative modifications to our existing, proven nasal technology platform, we developed Rhinoswab – a comfortable, easy to use swab that opens up the potential for mass, population-wide sample self-collection.
It was proven to be 100% accurate for the detection of SARS-COV-2 in spiking studies conducted by the Victorian Infectious Diseases Laboratory (VIDRL) when used in rt-PCR testing.
Rhinoswab is approved for sale as a Class 1 device in Europe (CE Mark), in the United States with the US Food and Drug Administration (FDA), and in Australia with the Therapeutic Goods Administration (TGA).
limitations with current swabs
Addressing unmet needs for safe, effective & comfortable sample collection
Small load capacity and limited loading time
May result in low sample yields, which can present an issue in the setting of a low viral load or viral assays with a high limit of detection (LoD).
Pain/discomfort associated with nasopharyngeal (NP) swabs
May contribute to a fear of testing and reluctance to get tested.
Infection risk to healthcare worker (HCW)
Close proximity to patient and risk of sneezing, gagging or coughing during sample collection compromises HCW safety.
Need for skilled healthcare worker to conduct or supervise all sample collections
Increases the burden of testing on the healthcare workforce and personalized protective equipment (PPE) utilization.
THE RHINOSWAB ADVANTAGE
Comfortable & pain free
Rhinoswab is comfortable to use addressing the problems with current nasopharyngeal swabs that are highly invasive and uncomfortable.
Rhinoswab is designed for self-collection in the home, at workplaces, clinical settings and anywhere that we need to test frequently and in large numbers.
Dual nostril application for high yield
The new Rhinoswab, with it’s dual swab heads has been shown to collect a 1.5 times larger sample than the standard of care swab, offering the potential for a more effective diagnostic sample.
Safer for healthcare workers
Easy self-collection with Rhinoswab reduces the risk to healthcare workers and the cost of personal protection equipment (PPE) required to protect them.
Improved standardization of collection
Less variability in collection technique may help reduce sampling & testing errors.
WORKS WITH BOTH LABORATORY AND POC TESTS
Rhinoswab can be used for both rt-PCR and antigen tests, working seamlessly in laboratory and POC environments with standard vials and transport media.
A new era in swab technology
Standard nasal swab
Variable placement within nose including anterior nares, mid-turbinate (deep nasal) and nasopharynx; latter can cause pain, discomfort and sneezing
Non-anatomical shape and small surface area of ‘bud’ tip limits contact area with nasal mucosa and sample yield
Composition varies by manufacturer and specimen site, e.g. full-sized or mini-tip made from flocked nylon, round foam or spun fiber (rayon, polyester)
Two insertions required to sample both nostrils
Long, flexible shaft can lead to ‘overshooting’ and ‘brain stab’ discomfort
Break-point enables tip to break off and fit into standard pathology vial
Pencil grip and head tilt required to handle and position tapered shaft
Sits comfortably within low-mid nasal turbinates for pain-free sampling
Anatomically designed ‘loop’ tip with large surface area mimics shape of nose to maximize contact area with the nasal mucosa, optimizing sample yield
Nylon-flocked loops for reliable sample uptake and release (latter further supported by hydrophobic treatment of loops)
Two-pronged swab means both nostrils can be sampled simultaneously
Short arms ensure swab goes no further than the low-mid turbinates when fully inserted, irrespective of nose size
Break-point enables loops to break off and fit into standard pathology vial
Handle with ‘thumb print’ allows for
easy, error-free positioning within nose
by patient or healthcare worker at any angle, which standardizes the sampling process
LEADING BODIES AGREE ANTERIOR OR MID-TURBINATE (DEEP NASAL) SWAB IN ISOLATION IS AN ACCEPTABLE SPECIMEN COLLECTION METHOD FOR DETECTION OF SARS-CoV-2
According to several recent peer-reviewed studies that have compared nasal swabs to NP or OP swabs, self-collected nasal swabs (supervised or at-home) represent a reliable alternative to NP/OP swabs collected by healthcare workers for the detection of SARS-CoV-2.2–5
Based on this evidence, both the US CDC and the FDA have approved self-collected nasal sampling (supervised or at-home) as an acceptable specimen collection method for SARS-CoV-2 testing.6,7
Usability study results
Self collection with rhinoswab is easy and provides consistently reliable samples for testing
In a study of swab collection for influenza testing, the majority of participants preferred self-collected swabs over those collected by healthcare workers, with no statistical difference in detecting the virus15.
Rhinoswab is suitable for use across a range of clinical and non-clinical settings
Collection by a healthcare worker or supervised self-collection in a clinical setting
- COVID-19 testing clinics
- GP clinics
- Pathology centres
Self collection in a non-clinical setting (where local guidelines permit)
- At work, especially in high risk occupations requiring high frequency testing
- At place of study
- At home
Safety & Tolerability
Superior comfort delivers high patient acceptability
In a usability survey conducted by Rhinomed1:
- 97.9% of participants reported NO discomfort or pain when using Rhinoswab
- 77.1% of participants described Rhinoswab as comfortable or very comfortable to use
Rhinoswab’s comfort factor may help reduce testing fears, overcoming reluctance to get tested
Anecdotal reports indicate that some individuals avoid or delay testing due to the pain/discomfort that may be experienced with traditional swabs.10
The superior comfort of Rhinoswab has the potential to improve patients’ willingness to undergo testing, thereby enhancing viral testing rates.
Rhinoswab is a safe alternative to standard of care swabs1
- There have been no adverse outcomes associated with Rhinoswab to date, other than occasional light nasal spotting when the swab is removed1
- There are no specific contraindications for collecting samples with Rhinoswab. However, similar to all other swabs11, clinicians should be cautious if the patient has had recent nasal trauma or surgery, has a markedly deviated nasal septum, has a history of chronically blocked nasal passages or severe coagulopathy, or is taking anticoagulant therapy
- Rhinoswab’s positioning in the low-mid nasal turbinates reduces the likelihood of sneezing during sample collection and avoids the risk of coughing/gagging that comes with NP/OP swabs. This mitigates the risk of aerosol generation at time of sampling, decreasing the infection risk to any healthcare workers in attendance3,12,13
Rhinoswab’s viral load transfer comparable to standard of care1
An independent laboratory, Gnomix (Adelaide, Australia) was engaged to compare the elution efficiency of the Rhinoswab™ compared to the standard of care nasal swab (Copan ESwab™).
The study found that the CT scores for the two swabs were comparable at 20 μl loading for both high and low virus burdens.
|High Virus Burden 20 μl (1ml Elution) Average Ct||25.45 (± 0.24)||25.75 (± 0.43)|
|Low Virus Burden 20 μl (1ml Elution) Average Ct||29.15 (± 0.24)||30.39 (± 1.03)|
The study also evaluated the sample yield or average sample recovery for the Rhinoswab compared to the standard of care nasal swab (Copan ESwab™).
|High Virus Burden 20 μl (1ml Elution)||16.34 μl (82%)||14.50 μl (73%)|
|Low Virus Burden 20 μl (1ml Elution)||21.80 μl (~100%)||17.33μl (87%)|
These results suggest a superior elution efficiency for the Rhinoswab when comparing identical initial loadings of both the high and low virus burden sample.
SARS-CoV-2 detected with 100% accuracy when rt-PCR test applied to infected Rhinoswab samples1
A SARS-CoV-2 spiked study was conducted at the Victorian Infectious Diseases Reference Laboratory (VIDRL) at the Peter Doherty Institute for Infection and Immunity.
The study evaluated the efficacy of Rhinoswab in transferring a viral load for testing compared to a commercially available standard flocked swab (Copan ESwab™) using reverse transcription-polymerase chain reaction (rt-PCR).
Both Rhinoswab and the Copan ESwab™ reported 100% accurate diagnosis of SARS-CoV-2

No. Rhinoswab is not a test.
There are three stages to conducting a covid test; 1) Collect a sample 2) analyse the sample 3) report the results. Rhinoswab provides a comfortable alternative to standard nasopharyngeal swabs for collecting the sample. Once Rhinoswab collects a sample from the nose, the swab is placed in a standard vial containing saline transport media and sent to a lab for testing. The test is conducted within the pathology laboratory using rt-PCR testing equipment.
Yes. Rhinoswab can be used with rt-PCR testing.
Rhinoswab is designed to be used with standard vials and transport media, fit seamlessly into pathology laboratory workflows and used on existing rt- PCR testing equipment.
Yes, nasal swabbing is a valid sample collection method.
Swabbing only the nose is a valid sample collection approach. Scientific literature and guidance provided by the FDA, CDC (Center for Disease Control) and WHO support the efficacy and reliability of nasal swabs that access just the front of the nose rather than the depth of the nasal cavity.
No Rhinoswab is self administered.
Rhinoswab is designed to be self administered to minimise risk to health care workers. Health care workers may supervise the sample collection process if necessary for those who are under 16 years of age or those who have cognitive or other challenges, but they will not be required to handle the swabs.
The Office of the Assistant Secretary of Health SARS – Co-V2 (COVID-19) Fact Sheet states: “Collection of nasal swab specimens is less technically complex, so can reduce the risk of the spread of infection to healthcare providers, by (1) reducing the duration of the procedure, and (2) allowing the patient to perform self-collection while under supervision.”
Self collection of nasal swab samples are safer for Health Care Workers who can supervise patients performing self collection from a distance rather than the HCW performing the collection.
The Office of the Assistant Secretary of Health SARS – Co-V2 (COVID-19) Fact Sheet recognizes that self collection of nasal samples “… also lessens PPE utilization, given that the patient can perform self-collection under supervision (versus the health care provider performing the collection).”
Yes. Rhinoswab is registered as a 510K exempt medical device in the US and as a Class 1 medical device with the TGA in Australia. We are currently awaiting CE Mark registration for Europe.
Rhinoswab is registered for use by anyone over the age of 16 years.
Yes. A usability study showed that 77.1% of participants found the swab to be very comfortable or comfortable and a further 20.8% found it to be neither comfortable nor uncomfortable.
No. A usability study showed that 97.9% of participants (47 out of 48 participants who took part in the trial) reported that they experienced no pain at all when using the swab.
In a spiking study undertaken by the Victorian Infectious Diseases Reference Laboratory, Rhinoswab was shown to be 100% a for the diagnosis of SARS-CoV-2 and equal to the current standard of care at both low and high viral loads.
Rhinoswab has been tested by the Victorian Infectious Diseases Reference Laboratory, part of the Peter Doherty Institute for Infection and Immunity (the Doherty) one of Australia’s preeminent covid-19 research and testing facilities.
