Breathe Your Way to a Covid Test in Under a Minute
Imagine spotting a new Covid test the size of a portable breathalyser—no lab, no waiting, just a quick inhale and you’re done. That’s the promise behind Breathonix’s prototype, a spin‑off from the National University of Singapore (NUS).
How It Works
The kit captures a patient’s breath into a little tube, then spits out a result in real time. Think of it as a “head‑-up” alert: breath in, test out, and you’re back to doing your thing—whether that’s flying across the globe or studying in a dorm.
Trial Highlights
- Accuracy: A pilot study with 180 patients at the National Centre for Infectious Diseases (NCID) hit over 90 % precision.
- Next Steps: The team plans to enroll another 600 patients in upcoming phases to sharpen the algorithm.
- Speed: Results come in under a minute, no PCR lab needed.
Why It Matters
Dr. Jia Zhunan, chief executive and NUS alum, says this could be a “game‑changer” for Singapore’s Covid response.
“It’s incredibly easy to administer, and you don’t need specialised staff or the lab hustle that comes with PCR,” Dr. Jia explains. “All the data is generated on the spot, which is perfect for high‑traffic places like airports and student dorms.
“Forget waiting for results: you’ll get a verdict right after you exhale that first breath.”
Looking Ahead
With the promise of speed and high accuracy, Breathonix’s breath test might soon become the go‑to way to screen anyone from a busy terminal to a quiet study room. Keep an eye on it—one breath could change the way we keep communities safe.
How the test works
Breathonix – The Breath‑Based Innovator
Most COVID kits are like detectives who chase clues: PCR hunts viral DNA fragments, and rapid antigen tests sniff out viral proteins.
Breathonix does something completely different—it listens to your breath for chemical vibes.
What Makes It Stand Out?
- No swab needed: It’s all about the exhale.
- Detects subtle chemical shifts: Think of it as reading your breath’s gossip.
- Instant insight: Get a quick snapshot of your viral status.
So, if you’re tired of the usual swab drama, try Breathonix – because breathing can be a powerful health detective.

Breath of Life: Your Exhale Might Be the New COVID Detector
What’s in a Breath?
Every sigh, guffaw, or sneezed breath carries microscopic villains—volatile organic compounds (VOCs). These sneaky chemicals are the fingerprints of our cells’ inner workings. They’re the same in everyone, but a healthy mix has a different flavor than the one churned out by someone fighting an illness.
“If you listen closely, the breath of a sick person sings a different tune,” says Dr Jia. “That’s why VOCs can act as a quick tell‑tale for diseases like Covid‑19.”
Already Out There: Breath Tests for Asthma and H. pylori
Breath tests aren’t brand‑new. Doctors already use them to spot asthma attacks and even the stomach‑bug Helicobacter pylori. The next frontier? A rapid, one‑minute test for Covid.
How Breathonix Makes a Breath Test Feel Like a High‑Tech Toy
- Step 1: The patient takes a quick blow into a disposable mouthpiece.
- Step 2: The exhaled air is fed into a super‑precise breath sampler.
- Step 3: The sample lights up in a cutting‑edge mass spectrometer.
- Step 4: On the back end, machine‑learning software crunches the VOC pattern.
- Step 5: The result pops up—ready in under a minute.
“Our mouthpiece has a one‑way valve and a saliva trap to keep the machine clean,” explains Mr Du Fang, Breathonix’s COO. “This tackles cross‑contamination like a champ.”
Expert Take‑away: A Screening Gimmick or Game‑Changer?
Dr Shawn Vasoo of the NCID says the test could serve as a screening tool, not a stand‑alone diagnose. “We’ll still see a good old PCR foam swab for confirmation,” he notes. He adds, “There’s promise, but we’re still in the early‑phase comparison era.”
Key Take‑aways
- VOCs in breath differ between healthy and sick individuals.
- Info on diseases can leak from a single exhale.
- Breathonix’s test delivers results in less than one minute.
- While exciting, it should work in tandem with PCR until we have more data.
Bottom line? Your breath might soon carry the same diagnostic weight as a swab—just with less awkwardness and more science hype. Stay tuned; the next scoop might just come straight from your lungs!
Translating research
Breathonix: From Dog Sniffing to Covid Detection
What’s the Backstory?
Back in 2019, the NUS Graduate Research Innovation Programme gave birth to Breathonix. Its first mission? To sniff out lung cancer before it even sneezes. The team, led by Dr Jia, wanted to turn exhaled breath into a diagnostic crystal ball.
How a 44‑Year‑Old Woman and Her Dog Sparked an Idea
Dr Jia’s inspiration came from a 1989 Lancet article. A 44‑year‑old lady found a weird patch on her thigh – her dog took to sniffing it like a pro. The diagnosis? Melanoma. And it turned out to be treatable.
- Dog’s keen nose flagging a potential cancer.
- Dr Jia thought: “If a dog can catch a dermatological clue, why can’t we detect other killers by breath?”
Fast‑Forward to the Pandemic
COVID‑19 hit exactly when Breathonix was gearing up. Instead of hitting the brakes, the CTO, Du Fang, nudged the algorithm to sniff out the new beast.
- Data set: 180 patients (48 COVID‑positive, 132 negative).
- Results: Sensitivity ~93 %—doctor’s first instinct was right about 9 out of 10 times.
- Specificity ~95 %—the test knows when someone’s breathing is clear as a fresh wind.
High‑Level Praise
Professor Freddy Boey, NUS Deputy President for Innovation, called it a “home‑grown hero” of Singapore’s tech scene. He noted that the breath‑analysis wizardry roots back to Dr Jia’s PhD work, and that now it’s helping Singapore’s fight against COVID‑19.
Looking Ahead
NCID’s Dr Vasoo is excited about rapid, real‑time screening tools. He says:
- Potentially lifesaving in settings where mass checks are needed.
- Validation is still on the road, but the path is promising.
Takeaway
From a dog’s intuition to a whirlwind of science, Breathonix is turning air into answers. The journey continues, and every breath might just hold the secret to catching disease early.
