Spirometry
SPR
Description
"Spirometry" test measures how much air you can breathe in and out and how quickly you can exhale, helping assess lung function. It’s widely used to diagnose asthma, COPD, and other obstructive lung diseases. The test involves exhaling into a device that tracks airflow and lung volume. Abnormal results may indicate airway blockage or restriction. Doctors use spirometry to confirm diagnoses, tailor treatment, and monitor progress. Regular testing helps manage symptoms and maintain long-term respiratory health.

Test Group Description
Basic Pulmonary Function Group: Essential tests for assessing respiratory health and function, providing foundational insights into lung capacity and airway function. Complete Pulmonary Function Group: Comprehensive evaluations of respiratory function offer detailed insights into lung function, airway inflammation, and structural abnormalities, facilitating the precise diagnosis and management of pulmonary conditions. Physical Function Group: Tests within this group assess various aspects of physical function, offering insights into an individual's mobility, strength, and endurance. These tests help evaluate overall physical health and identify potential limitations or areas for improvement.
Optimal Range
For All Individuals:
Conventional Unit:
FEV₁/FVC Ratio: > 0.75 | FEV₁: 85–100% | FVC: 85–100% | TLC: 85–100% | DLCO: 80–100%SI Unit: Not Applicable
Normal Range
For All Individuals:
Conventional Unit: FEV₁/FVC Ratio: > 0.70 | FEV₁: > 80% | FVC: > 80% | TLC: > 80% | DLCO: > 75%
SI Unit: Not Applicable
Results That Differ From The Norm (Direct and Indirect Causes)
Abnormal results may indicate:
Acute respiratory distress syndrome (Severe lung condition causing difficulty breathing)
Alpha-1 antitrypsin deficiency (Genetic disorder affecting lung function)
Asthma (Chronic inflammatory condition affecting the airways)
Bronchiectasis (Chronic lung condition characterized by abnormal widening of the airways)
Bronchiolitis obliterans ...
Key Reasons For Testing
Pulmonary Function Assessment: Evaluates airflow, volume, and lung capacity to detect respiratory impairments.
Diagnosis of Respiratory Disorders: Differentiates between obstructive and restrictive lung diseases such as asthma and COPD.
Treatment Planning: Guides management by assessing severity, monitoring progression, and evaluating therapy response.
Preoperative Risk Assessment: Assesses pulmonary function to evaluate surgical risks and inform perioperative care.

Important Note
Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.
Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
