On June 4 morning, a Vingroup representative sent the Ministry of Health 30 Covid breathalyzers and 2 million test samples, worth more than VND 460 billion (US$ 20 million). Those are the first Covid-19 breath test machines in Vietnam. The machine can detect coronavirus through breath in just 60 seconds.

Accepting the gift, Minister of Health Nguyen Thanh Long expected that with the new technology testing equipment, Vietnam's testing capacity would be strengthened, thereby reducing the burden for medical staff, helping to deploy faster testing. He also said that in this recent pandemic outbreak, Vietnam's testing capacity reached more than 2.8 million samples, which was "equal to the total number of samples in the previous three outbreaks combined."

How Covid-19 breath test machine works?

The breathalyzer, produced by Breathonix, comprises a disposable single-use mouthpiece, a breath sampler, and a mass spectrometer. Users exhale into the mouthpiece, with their breath being collected by the sampler. From there, the captured air is fed into the spectrometer and analyzed using Breathonix’s algorithm.

Current polymerase chain reaction (PCR) tests for COVID-19 currently taking an average of 24-48 hours to produce results, while this new technology announces test results in less than one minute.

The system works by analyzing the volatile organic compounds (VOCs) in each exhaled breath to identify those that the algorithm has been trained to recognize as uniquely associated with the coronavirus, according to Business Today.

The machine got approved by the Singapore government in May 2021. The test is said to be the first of its kind to obtain provisional authorization in the country.

Covid-19 breath test - similar technology worldwide

Other countries, including Indonesia, France, and the Netherlands, have rolled out similar breath tests. The Netherlands was the first in the world to have “breathalyzer” testing for Covid-19 that can sniff out the disease based on a mix of chemical components exhaled by the patient, according to Science Mag.

The Dutch breath test machine, called SpiroNose was first introduced to medical facilities in Amsterdam in February 2021. It contains seven metal oxide semiconductor sensors that detect thousands of volatile organic compounds in exhaled air.

Channel News Asia reported that Indonesia in February 2021 also rolled out Covid-19 breath tests by a machine called GeNose, which says it detects the reaction between the coronavirus and body tissue in the respiratory tract with at least 95% accuracy.

Researchers in France have developed a breath test for Covid-19 since August 2020, according to Anadolu Agency. The machines come into use in May 2021, utilizeing a machine that tests droplets as patients exhale into a tube, much like a standard breathalyzer test.
