Lung Diseases Diagnosis: 8 Advanced Test For Better Health

Diagnosing lung diseases often involves a combination of medical history, physical exams, imaging tests, and pulmonary function tests. Common lung diseases include asthma, chronic obstructive pulmonary disease (COPD), pneumonia, tuberculosis, lung cancer, and interstitial lung disease.

 

8 Test for Lung Diseases

There are various tests that can be used to diagnose lung diseases, including:

1. Spirometry

  • Spirometry measures how much air a person can breathe in and out, and how quickly they can exhale.
  • This test can help diagnose and monitor respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and pulmonary fibrosis.
  • During spirometry, a person breathes into a machine called a spirometer, which records the amount and speed of air they exhale.
  • The results of the test can provide information about lung capacity, airflow, and any obstructions or limitations in the airways.
Test Name Spirometry
Also Known As Pulmonary function test
Purpose Assessing lung function
Sample Breath
Preparation None
Procedure Measuring breath volumes and airflow
Test Timing Varies
Test Price (INR) 500-1500
Result Value Lung function parameters

Interpretation Evaluate lung capacity and airflow limitations

Measure lung function with Spirometry (Pulmonary function test) to assess airflow limitations and lung capacity.

 

2. Pulmonary Function Tests

  • Pulmonary function tests (PFTs) evaluate the performance of the lungs and diagnose lung diseases.
  • This group of diagnostic tests helps to measure the lung's ability to move air in and out and their capacity to absorb oxygen.
  • These tests can help diagnose a variety of lung diseases, such as asthma, chronic obstructive pulmonary disease (COPD), and pulmonary fibrosis.
  • PFTs can also be used to monitor the progression of lung disease and assess the effectiveness of treatment.
  • The tests typically involve breathing into a machine that measures various aspects of lung function, such as lung capacity, airflow, and gas exchange.
  • The results of PFTs can help doctors determine the best course of treatment for a patient's lung disease.
Test Name Spirometry
Also Known As Pulmonary function test

3. Chest X-ray

  • Chest X-ray is a common diagnostic imaging test that uses a small amount of radiation to produce images of the structures inside the chest, including the heart, lungs, and blood vessels.
  • It is a non-invasive, relatively low-cost imaging test that can detect conditions such as pneumonia, lung cancer, and chronic obstructive pulmonary disease (COPD).
  • It can help diagnose a range of respiratory diseases, such as pneumonia, lung cancer, and pulmonary fibrosis, as well as other conditions that affect the chest and lungs, including heart disease and injuries.
  • During the test, the patient stands in front of the X-ray machine and takes a deep breath while the X-ray is taken.
  • The images produced can be used by healthcare providers to diagnose or monitor respiratory diseases, evaluate the effectiveness of treatment, and plan further care.
Test Name Chest X-ray for Lung Disease

4. CT Scan

  • A CT (computed tomography) scan is a type of imaging test that uses X-rays and computer technology to produce detailed images of the lungs and other internal organs.
  • It can be used to diagnose lung diseases, such as lung cancer, pulmonary embolism, and pneumonia, as well as to monitor the progression of certain lung conditions.
  • During a CT scan, a patient lies on a table that slides into a large, donut-shaped machine.
  • The machine takes multiple X-ray images from different angles and combines them to create detailed cross-sectional images of the lungs and other areas of the body.
  • A CT scan may require the use of contrast dye to enhance the images, which is typically given through an IV in the arm.
  • CT scans are generally considered safe, but they do expose patients to a small amount of radiation.

5. Bronchoscopy

  • Bronchoscopy is a diagnostic test used to examine the airways of the lungs.
  • It involves inserting a thin, flexible tube with a light and camera on the end through the nose or mouth and into the lungs.
  • The images captured by the camera help doctors identify any abnormalities or blockages in the airways.
  • Bronchoscopy can also be used to collect tissue samples or perform other procedures, such as removing foreign objects or tumors.
  • Under either local or general anesthesia, pulmonary function tests (PFTs) are typically conducted to evaluate the respiratory function of the lungs.
  • It can also be used to treat certain lung conditions. By providing a direct view of the airways, bronchoscopy can help identify the cause of respiratory symptoms and guide appropriate treatment.
Test Name Bronchoscopy
Also Known As Bronchoscopic examination
Purpose Diagnostic and therapeutic procedure for lung diseases
Sample Visual examination of the airways and collection of tissue samples
Preparation Fasting, sedation, and consent

Result Value Tissue samples, visual findings
Normal Value Absence of abnormal findings
Accuracy High
Interpretation Diagnosis, evaluation, and treatment guidance

Bronchoscopy (also known as bronchoscopic examination) is a diagnostic and therapeutic procedure for lung diseases.

 

6. Biopsy

  • Biopsy is a medical procedure where a sample of tissue is taken from the body to be examined under a microscope.
  • In the case of lung diseases, a lung biopsy may be performed to diagnose certain conditions, such as lung cancer or interstitial lung disease.
  • There are several types of lung biopsy, including bronchoscopic biopsy, needle biopsy, and surgical biopsy.
  • The type of biopsy performed will depend on the location of the abnormal tissue and other factors specific to the individual case.
  • Biopsies are generally considered safe, but like any medical procedure, they do carry some risks, such as bleeding or infection.
  • However, the benefits of a biopsy in diagnosing lung diseases often outweigh the risks.

7. Blood Tests

  • Blood tests are one of the diagnostic tests used to evaluate lung diseases.
  • These tests are usually performed to identify the underlying cause of respiratory symptoms or to monitor the progression of the disease.
  • Blood tests can help diagnose certain lung diseases such as infections, autoimmune disorders, and cancer.
  • The blood samples are usually taken from a vein in the arm, and the tests can measure various parameters such as oxygen and carbon dioxide levels, inflammatory markers, and blood cell counts.
  • The results of blood tests can help healthcare providers determine the appropriate treatment and management plan for the patient.

8. Pulse Oximetry

  • Pulse oximetry is a non-invasive test used to measure the oxygen saturation level in the blood.
  • It involves placing a small sensor on a fingertip, earlobe, or toe that emits light that passes through the skin and detects the amount of oxygen in the blood.
  • The test is quick, painless, and can be done in a doctor's office or hospital setting.
  • Pulse oximetry is often used to monitor oxygen levels in people with respiratory conditions, such as asthma or COPD, as well as during surgery or other medical procedures.
  • It can also be used to detect early signs of hypoxia, a condition where the body doesn't receive enough oxygen.

Lung Diseases Diagnosis FAQ

What blood tests detect lung problems?

Blood tests can detect lung problems by measuring the levels of certain markers in the blood. Some blood tests used to diagnose lung problems include arterial blood gas test, complete blood count (CBC), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR).

What is Type 4 lung disease?

Type 4 lung disease, also known as cell-mediated or delayed hypersensitivity pneumonitis, is a lung condition that occurs when the immune system responds abnormally to inhaled particles, leading to inflammation and damage in the lungs.

Can an ECG detect lung problems?

While an electrocardiogram (ECG or EKG) primarily measures the electrical activity of the heart, it can sometimes provide indirect information about lung problems. For example, a condition called pulmonary embolism, which is a blockage of the pulmonary artery in the lungs, can cause changes in the ECG that suggest heart strain or damage.

Can you test lung function at home?

There are several types of devices available that can be used to measure lung function at home, such as peak flow meters and spirometers. However, it is important to note that these devices may not be as accurate as the tests performed in a medical facility and should not be used as a substitute for professional medical advice and care.
