Breath test may soon predict asthma attacks

Dr Elaine Vickers, Research Relations Manager at Asthma UK, said: ‘We know that exhaled NO levels and inflammation in the lungs often go hand in hand, and that high levels of NO can indicate that a person’s asthma is uncontrolled. 'What researchers are not sure of yet is whether this information is sufficient to decide what medicines a person should take. ‘The creation of sensitive and accurate hand-held NO monitors such as this is a welcome step forward, however they will require careful evaluation. ’
