As a medical professional with over 15 years of experience in respiratory medicine, I have witnessed countless patients benefit from proper lung function testing. The PFT DLCO test has become increasingly important in Nagpur, especially given our city’s air quality challenges and growing respiratory concerns.
Let me guide you through everything you need to know about getting a PFT DLCO test in Nagpur, from understanding the procedure to finding the best facilities in our city.
What is PFT DLCO Test and Why Do You Need It
The Pulmonary Function Test with Diffusion Capacity of Lungs for Carbon Monoxide (PFT DLCO) is a specialized breathing test that measures how well your lungs transfer oxygen from the air into your bloodstream. I often explain to my patients that while regular spirometry tests check how much air you can breathe in and out, the DLCO test specifically examines how efficiently your lungs can absorb gases.
In Nagpur, where air pollution levels have been a growing concern, this test has become particularly valuable. The test helps detect early signs of lung damage that might not show up in regular breathing tests.
Understanding the DLCO Component
The DLCO portion of the test uses a small amount of carbon monoxide mixed with other gases. Don’t worry – the amount is extremely safe and much less than what you’d get from a single cigarette. During my practice, I’ve performed thousands of these tests, and I can assure you the procedure is completely safe.
The test measures how quickly carbon monoxide moves from your lungs into your blood. This gives us important information about the health of the tiny air sacs (alveoli) in your lungs and the blood vessels around them.
Step-by-Step PFT DLCO Test Procedure
Based on my experience conducting these tests, here’s exactly what happens during a PFT DLCO test in Nagpur hospitals-
Before the Test You’ll sit comfortably in a chair next to the testing equipment. The technician will explain the procedure and answer any questions. I always tell my patients to wear comfortable, loose-fitting clothes that won’t restrict breathing.
During the Test
- You’ll breathe normally through a mouthpiece connected to the testing machine
- The technician will place a soft clip on your nose to ensure all breathing happens through your mouth
- You’ll be asked to take the deepest breath possible
- Then breathe out as hard and fast as you can for several seconds
- For the DLCO portion, you’ll inhale a special gas mixture and hold your breath for 10 seconds
- Finally, you’ll exhale completely into the machine
Test Duration The entire procedure typically takes 30-45 minutes. The actual breathing tests last only a few minutes, but we repeat them several times to ensure accuracy.
Cost of PFT DLCO Test in Nagpur
The cost of PFT DLCO testing varies across different facilities in Nagpur, with prices typically ranging from Rs 630 to Rs 2400. Based on my research and patient feedback, here’s what you can expect-
Government Hospitals
- GMCH (Government Medical College Hospital) – Rs 500-800
- IGGMC (Indira Gandhi Government Medical College) – Rs 600-900
Private Hospitals
- Orange City Hospital – Rs 1200-1800
- Kingsway Hospital – Rs 1000-1500
- Care Hospital – Rs 1500-2000
- Wockhardt Hospital – Rs 1800-2400
Diagnostic Centers
- Most standalone diagnostic centers charge between Rs 800-1200
The price difference usually reflects the quality of equipment, expertise of technicians, and additional services provided. I always advise my patients to prioritize accuracy over cost when choosing a facility.

Understanding Your DLCO Test Results
The DLCO test measures how much carbon monoxide is absorbed during a controlled breath-holding period of 10 seconds. Results are compared to predicted values based on your age, height, gender, and ethnicity.
Normal DLCO Values
- Typically 80-120% of predicted value
- Varies with age, height, and overall health
- Higher values in younger, taller individuals
Low DLCO Values May Indicate
- Emphysema or COPD
- Pulmonary fibrosis
- Pulmonary embolism
- Anemia
- Heart disease affecting lungs
High DLCO Values May Suggest
- Polycythemia (increased red blood cells)
- Left-to-right heart shunts
- Asthma (during acute episodes)
I always emphasize to patients that results must be interpreted by a qualified pulmonologist, considering your symptoms, medical history, and other test results.
Who Should Get PFT DLCO Testing
During my practice, I’ve recommended DLCO testing for patients with various conditions-
Respiratory Symptoms
- Unexplained shortness of breath
- Chronic cough lasting more than 8 weeks
- Chest tightness or pain
- Reduced exercise tolerance
Occupational Exposure In Nagpur, with our industrial background, workers exposed to-
- Asbestos
- Silica dust

Frequently Asked Questions
What is the difference between regular PFT and PFT with DLCO?
Regular PFT measures how much air you can breathe in and out and how fast you can do it. PFT with DLCO also measures how well your lungs can transfer oxygen from the air into your bloodstream. The DLCO component provides additional important information about lung health that regular spirometry cannot detect.
Is the DLCO test safe?
Yes, the DLCO test is completely safe. The small amount of carbon monoxide used is much less than what you would get from environmental exposure or a single cigarette. I have conducted thousands of these tests without any safety issues.
How long does the PFT DLCO test take?
The complete test usually takes 30-45 minutes. The actual breathing portion takes only a few minutes, but we repeat measurements several times to ensure accuracy. Plan to spend about an hour at the facility including registration and waiting time.
Can I take my regular medications before the test?
This depends on your specific medications. Some inhalers and bronchodilators should be stopped before testing, while others can be continued. Always inform your doctor about all medications you’re taking and follow their specific instructions.
What should I wear for the test?
Wear loose, comfortable clothing that doesn’t restrict your breathing. Avoid tight-fitting shirts, belts, or undergarments. Comfortable shoes are recommended as you’ll be sitting for the duration of the test.
Why do I need to hold my breath during the DLCO test?
Holding your breath for 10 seconds allows the carbon monoxide in the test gas to have enough time to cross from your lungs into your bloodstream. This measurement tells us how well your lung tissue can transfer gases, which is crucial information about lung health.
Can children get PFT DLCO testing?
Yes, children over 6 years old can usually perform the test successfully if they can follow instructions and cooperate. However, results must be interpreted differently for children, and some facilities specialize in pediatric pulmonary function testing.
How often should I repeat DLCO testing?
The frequency depends on your condition. For monitoring known lung diseases, testing might be done every 6-12 months. For occupational screening, annual testing is common. Your doctor will recommend the appropriate interval based on your specific situation.
What if I have claustrophobia?
The test doesn’t involve enclosed spaces. You sit in a regular chair and breathe through a mouthpiece. If you have severe anxiety about medical procedures, discuss this with your doctor beforehand. Some facilities can provide mild relaxation techniques.
Are there any side effects after the test?
Most people have no side effects. Rarely, some patients might feel slightly lightheaded from the deep breathing exercises. This is temporary and resolves quickly. The small amount of carbon monoxide used doesn’t cause any lasting effects.
Can smoking affect my DLCO results?
Yes, smoking significantly affects DLCO results. Current smokers typically have elevated carboxyhemoglobin levels which can interfere with accurate measurement. It’s recommended to avoid smoking for at least 24 hours before the test, though longer is better.
What happens if my DLCO results are abnormal?
Abnormal results don’t necessarily mean you have a serious condition. Your doctor will interpret results alongside your symptoms, medical history, and other tests. Further evaluation might include chest imaging, blood tests, or consultation with a lung specialist.
