Answer:

The diagnostic test used in the daily measurement for early detection of asthma exacerbations is the peak expiratory flow rate (PEFR) measurement. PEFR is a simple test that measures the maximum airflow rate that can be achieved during a forceful exhalation. It is often done using a handheld device called a peak flow meter. By measuring PEFR regularly, individuals with asthma can track their lung function and detect any changes that may indicate worsening asthma symptoms or an impending asthma exacerbation. Monitoring PEFR can help patients and healthcare providers adjust asthma medications and treatment plans accordingly to prevent severe exacerbations.
