What is the primary indication of spirometry in medical diagnostics?

  1. Confirming asthma diagnosis

  2. Measuring heart rate

  3. Assessing kidney function

  4. Evaluating liver health

The correct answer is: Confirming asthma diagnosis

In medical diagnostics, spirometry is primarily used to confirm the diagnosis of asthma. It measures the volume and flow of air that is inhaled and exhaled by the lungs. This is important in diagnosing asthma as it can help determine if there is any obstruction or difficulty in airflow. The other options listed are not primary indications of spirometry. Measuring heart rate is better done with an electrocardiogram (ECG), assessing kidney function is done through blood or urine tests, and evaluating liver health is typically done through imaging or blood tests. While spirometry may provide some information about heart and lung function, it is not the primary method for assessing these areas of health.
