Breath diagnostics is a cutting-edge field that harnesses the power of exhaled Breath to uncover crucial insights about an individual’s health. 

By analyzing the composition of breath, clinicians and researchers can detect diseases, assess metabolic states, and monitor various conditions non-invasively.

What is Breath Diagnostics?

Breath Diagnostics is a type of medical testing that uses non-invasive technology to help with clinical diagnosis. It works by analyzing the breath we exhale, which contains thousands of volatile organic compounds (VOCs). (1)

These VOCs are the primary constituents in breath analysis, and they can tell us a lot about our health.

The main purpose of breath Diagnostics is to detect diseases early and monitor health conditions. It’s a simple and painless method that can provide valuable information about the body’s physiological and metabolic processes. 

The most common things measured in Breath Diagnostics today include carbon dioxide, nitric oxide, ammonia, and some VOCs related to specific diseases. For example, higher levels of carbon dioxide can indicate lung disease, while certain VOCs can help detect cancer or liver disease.

Overall, breath diagnostics is a promising field that could revolutionize the way we diagnose and monitor diseases. It’s a perfect blend of medical testing and non-invasive technology, making it a vital tool in clinical diagnosis. 

What Disease Can Be Detected By Breath?

Did you know that your breath can reveal a lot about your health? Doctors can detect certain diseases like asthma, lung cancer, and even diabetes by analyzing your breath. 

The most common types of diseases that can be detected by breath include respiratory, malignant, neurodegenerative, metabolic, bacterial infections, and viral infections. (2)

• Respiratory: Asthma, COPD, obstructive sleep apnea syndrome, pulmonary arterial hypertension, cystic fibrosis
• Malignant: Lung, gastric, head and neck, breast, colon, prostate cancer
• Neurodegenerative: Alzheimer’s disease, Parkinson’s diseases, multiple sclerosis
• Metabolic: Diabetes, hyperglycemia
• Bacterial infections: Upper respiratory tract infection, Mycobacterium tuberculosis, Pseudomonas, Helicobacter pylori infection
• Viral infections: SARS-CoV-2

They use special tools and machines like a spirometer, breathalyzer, or a gas chromatograph. These tools measure things in your breath, such as the amount of air you can blow out or specific chemicals. 

For example, if your breath has high levels of acetone, it might mean you have diabetes or are in ketosis because you are following the keto diet. 

This is because when your body can’t use sugar for energy, it burns fat instead, producing acetone. It’s amazing how your breath can give clues about your health! 

Types of Breath Diagnostics

There are several types of breath tests that doctors use today. For example, detecting high levels of acetone, infection, lung function, and even stomach conditions. 

Breath Acetone

Breath acetone diagnostics is a simple way to monitor health conditions, like diabetes or ketone levels, when you’re on a keto diet. (3)

Breath acetone is measured with a breath ketone meter. This breath sensor detects ketones – chemicals your body makes when it burns fat for fuel. 

When your body doesn’t have enough insulin to turn sugar into energy, it starts burning fat, which makes ketones. That’s why people with diabetes often have high levels of ketones, which can be dangerous. 

On the other hand, people on a keto diet aim to burn fat by intentionally producing ketones. The breath analysis of acetone gives a quick and non-invasive way to measure these ketones. 

So, if you’re diabetic or on a keto diet, a ketone breath meter can help you keep track of your health in real time. 

Volatile Organic Compounds (VOCs)

Volatile Organic Compounds, or VOCs, are a type of chemical that can be found in our breath. These chemicals can be used for disease detection, making them very useful for science. (4)

When we’re sick, our bodies can produce different types of VOCs. These changes can be detected in our exhaled breath, kind of like how a dog can smell things we can’t. 

This type of breath analysis is a super useful tool for doctors. They can take breath samples and use them to detect diseases.

Today, the most common tool for diagnosing VOCs is the Electronic nose. This device can identify the complete mixture of VOCs in a person’s breath.

There’s even a company, Breathomix BV, that has developed an advanced technology that can diagnose lung cancer up to two years earlier than the usual clinical care. 

BreathBase can also tell doctors who will respond well to immunotherapy and it can distinguish different subtypes of diseases like asthma and COPD. 

Because of this, doctors can provide more personalized and precise treatment for their patients. So, VOCs analysis is not only helping detect diseases, but also improving the way we treat them. 

Breath Aerosol Analysis

Breath aerosol analysis is a new and promising way to check your respiratory health. It’s part of cutting-edge healthcare technology that involves testing the tiny particles you breathe out. (5)

These particles come from your respiratory tract, which is just a fancy term for the path that air takes in and out of your lungs.

By studying these particles, doctors can directly diagnose diseases like Influenza. They can also keep an eye on the stuff inside your respiratory lining fluid, like proteins and phospholipids. 

There’s no one-size-fits-all way to sample these exhaled particles. Doctors can use filters, impactors, impingement filters, or even electrostatic precipitators. 

What are Breath Metabolites?

Breath metabolites are chemicals in our breath that can tell us about our health. They’re made up when our body breaks down food, drink, and medicine. (6)

Some key ones include acetone, isoprene, and hydrogen sulfide. These make up a small part of our breath, less than 1%. 

We can find these using breath tests. These tests use technology like mass spectrometry, which can measure the amount and type of chemicals in our breath. 

This is good to know because it can help doctors find out if we’re sick or not. So, breath metabolites are really important for our health. 

What Are Breath Biomarkers?

Breath biomarkers are signals in our breath that can tell us about our health. Just like doctors test our blood for various markers, scientists have found we can do the same with our breath. (7)

These markers include things like chemicals or compounds that show up in your breath when you’re sick. 

For example, if your breath has a lot of acetone, it could mean you have diabetes. 

Breath biomarkers are important because they could help us diagnose diseases early. This means we could start treatment sooner and have a better chance of getting better. 

What Types of Breath Analysis Techniques Are There?

Breath analysis is a method used to find signs of disease. It’s non-invasive, meaning it doesn’t hurt or cause discomfort. There are three main types. (8)

• First, there’s gas chromatography which identifies and measures substances in your breath. 
• Second, we have electronic nose devices. These can detect specific odor patterns related to health issues. 
• Lastly, there’s infrared spectroscopy. It uses light to analyze chemical compounds in your breath. 

Each technique has its pros and cons. However, all of them provide a very helpful tool in diagnosing and monitoring various health conditions. It’s amazing how much our breath can tell us about our health!
