Essential Lab Tests for Diagnosing Shortness of Breath
Shortness of breath (Dyspnea) is a condition where a person experiences difficulty in breathing, and this can be caused by various conditions such as asthma, bronchitis, pneumonia, COPD, allergies, heart disease, or other pulmonary disorders. To accurately diagnose the underlying cause, it is important to conduct various lab tests, which help identify the nature and root cause of the condition.

Essential Lab Tests for Diagnosing Shortness of Breath
1. Spirometry Test
What is tested?
This test evaluates lung function by measuring how much air the lungs can take in and expel.
For whom is it required?
- Asthma
- COPD
- Chronic shortness of breath
Results:
This test helps determine the level of airway obstruction and constriction.
2. Pulse Oximetry
What is tested?
This test measures the oxygen levels in the blood.
For whom is it required?
- People with pulmonary disease
- COVID-19 patients
- Individuals with heart and lung conditions
Results:
Normally, an oxygen saturation level (SpO2) of 95% to 100% is considered normal. Levels below 90% may indicate serious issues.
3. Arterial Blood Gas (ABG) Test
What is tested?
This test measures the levels of oxygen (O₂), carbon dioxide (CO₂), and pH in the blood.
For whom is it required?
- Those experiencing severe shortness of breath
- To evaluate lung function
- For heart patients
Results:
A normal pH range is between 7.35 and 7.45. If the pH level is below 7.35, it indicates acidosis, and above 7.45, it suggests alkalosis.
4. Chest X-Ray
What is tested?
This test helps to identify lung structure and infections.
For whom is it required?
- Pneumonia
- Fluid buildup in the lungs
- Bronchitis or Tuberculosis (TB)
Results:
Helps detect infections, inflammation, or the presence of tumors in the lungs.
5. CT Scan
What is tested?
This test provides a detailed image of the lungs, clearer than an X-ray.
For whom is it required?
- If lung cancer is suspected
- Complications from COVID-19 or pneumonia
- Issues within the lung cavity
Results:
This test helps identify internal lung structures and infections more precisely.
6. Electrocardiogram (ECG)
What is tested?
This test analyzes the heart’s electrical signals and functioning.
For whom is it required?
- If shortness of breath is due to heart disease
- Suspected heart attack or heart block
Results:
An ECG can detect irregular heartbeats or blocks.
7. Allergy Test
What is tested?
This test identifies substances that could cause shortness of breath due to allergies.
For whom is it required?
- Those with dust, pollen, or food allergies
Results:
Helps identify which allergens are causing shortness of breath.
Conclusion
Accurate lab tests are essential for diagnosing the root cause of shortness of breath. By undergoing appropriate tests as advised by a healthcare provider, it becomes possible to protect lung and heart health. If shortness of breath persists over time, it is crucial to seek immediate medical attention.
