Advanced Pulmonary Diagnostics

Respiratory illnesses are often complex and deceptively silent. At times, what appears to be a common cough could conceal early-stage interstitial lung disease, or mild shortness of breath may signal more than just fatigue. In complex cases like these, surface-level evaluations are simply not enough—what you need is depth, diagnostic precision, and expert care.
At the forefront of respiratory diagnostics, Dr. Kishan Srikanth, MD, DM, a leading pulmonologist in Hyderabad, integrates world-class investigative tools with clinical acumen to uncover hidden pathologies. With his deep specialization in interventional pulmonology and critical care, he ensures each patient receives an accurate diagnosis—without guesswork. When you choose to consult one of the best lung specialists in Hyderabad, you’re not just pursuing treatment; you’re seeking answers that drive effective healing.

Advanced Pulmonary Diagnostics

01. Spirometry

Recognized as a benchmark in pulmonary assessment, spirometry quantifies airflow limitations with precision and reliability. This test measures the volume and speed of air that you can inhale and exhale, allowing your pulmonologist to assess the condition of your lungs and airways. It plays a critical role in diagnosing and managing various lung disorders, including:

Asthma: Detecting airflow obstructions and bronchospasm.

Chronic Obstructive Pulmonary Disease (COPD): Evaluating airflow limitations and disease progression.

Bronchitis and Obstructive Lung Diseases: Assessing Airway Blockages.

Pre-surgical Evaluation: Analyzing lung function for patients undergoing surgery.

With Spirometry, Dr. Kishan Srikanth provides a comprehensive evaluation of your lung health, delivering clarity on symptoms such as chronic cough, wheezing, and shortness of breath. This test also helps to track changes in lung function over time, ensuring the management plan is adjusted to suit your evolving needs.

02. DLCO (Diffusing Capacity of the Lungs for Carbon Monoxide)

A cornerstone in advanced pulmonary diagnostics, DLCO measures how efficiently oxygen transfers from your lungs into your bloodstream, often detecting disease before symptoms surface.

Pulmonary Fibrosis gauges scarring severity and oxygen transfer impairment.
COPD & Emphysema identifies gas-exchange abnormalities, refining disease management.
Pulmonary Hypertension flags early vascular-lung compromise.
Pre-Transplant Assessment determines lung function readiness for surgery.

Under the expert supervision of Dr. Kishan Srikanth, a leading pulmonologist in Hyderabad. DLCO testing offers a precise, patient-customized evaluation, empowering proactive lung health management.

03. FeNO (Fractional Exhaled Nitric Oxide)

FeNO testing is a state-of-the-art, non-invasive diagnostic tool designed to assess airway inflammation, a key feature in asthma and allergic respiratory conditions. By measuring nitric oxide levels in your exhaled breath, this test offers crucial insights for:

Asthma Diagnosis: Differentiates allergic and non-allergic asthma, even when symptoms are unclear.

Inflammation Monitoring: Tracks airway inflammation for timely treatment adjustments.

Personalized Care: Optimizes therapy based on real-time lung health.

Allergic Disorders: Identifies allergy-induced airway inflammation for targeted care.

Dr. Kishan Srikanth, an experienced allergy specialist and trusted lung specialist in Hyderabad, uses FeNO to provide precise, targeted care, optimizing asthma and respiratory treatment with real-time inflammation monitoring.

04. IOS (Impulse Oscillometry)

Impulse Oscillometry (IOS) is an advanced diagnostic tool that uses sound waves to assess lung function, detecting subtle abnormalities often missed by traditional spirometry. It is mainly useful for:

Early Detection: Identifies early signs of asthma, COPD, and other conditions.

Sensitive Monitoring: Tracks lung disease progression before symptoms appear.

Small Airways Assessment: Focuses on small airways often overlooked in traditional tests.

Pediatric cases and non-compliant patients benefit from this non-invasive, patient-centric diagnostic approach.

As a leading interventional pulmonologist, Dr. Kishan Srikanth uses IOS to provide accurate lung assessments, enabling early intervention and personalized care for optimal respiratory health.

05. High-Resolution CT Chest (HRCT)

High-resolution CT Chest (HRCT) is an advanced imaging technique that provides detailed cross-sectional views of the lungs, offering far more clarity than traditional X-rays. This non-invasive procedure is indispensable for:

Interstitial Lung Diseases: The gold standard for detecting conditions like pulmonary fibrosis and sarcoidosis.

Tumors and Lesions: Critical for the early detection of lung cancer and benign tumors.

Vascular Abnormalities: Helps identify pulmonary embolism and hypertension.

Disease Monitoring: Enables tracking of chronic lung conditions

Dr. Kishan Srikanth utilizes HRCT to gain a comprehensive understanding of your lung health, ensuring precise diagnoses and personalized treatment plans. This technology ensures optimal care and targeted interventions.

What are advanced pulmonary diagnostics?

Advanced pulmonary diagnostics refer to specialized tests and procedures used to evaluate lung function, detect structural abnormalities, identify infections, and diagnose complex respiratory disorders with high accuracy.

When should I consider undergoing pulmonary diagnostic testing?

If you experience chronic cough, breathlessness, chest tightness, unexplained fatigue, or have a history of asthma, COPD, or interstitial lung disease, diagnostic evaluation is essential for early and accurate detection.

What tests are included under advanced pulmonary diagnostics?

Key tests include pulmonary function tests (PFTs), high-resolution CT (HRCT) chest scans, bronchoscopy, endobronchial ultrasound (EBUS), diffusion studies, pleural fluid analysis, and sleep studies.

Is bronchoscopy a painful or risky procedure?

No. Bronchoscopy is a minimally invasive, well-tolerated procedure performed under local anesthesia or mild sedation. It allows real-time visualization of airways and is crucial for both diagnosis and biopsy.

What is EBUS, and when is it recommended?

Endobronchial Ultrasound (EBUS) is an advanced technique that uses ultrasound during bronchoscopy to visualize and sample lymph nodes or masses in the chest. It’s recommended for diagnosing lung cancer, TB, and sarcoidosis.

How accurate are these diagnostic tests?

When performed by an experienced interventional pulmonologist, advanced diagnostic procedures offer high sensitivity and specificity, significantly improving diagnostic accuracy for complex pulmonary conditions.

Are these diagnostics safe for elderly or high-risk patients?

Yes. Most procedures, including bronchoscopy and PFTs, are safe when performed with proper pre-procedure assessment and monitoring, even in elderly or comorbid patients.

How long does it take to get results?

Basic test results (like PFTs or imaging) may be available the same day. Biopsy or culture results may take 48–72 hours, depending on the type of analysis required.

Do I need to stop any medications before undergoing these tests?

In some cases, specific medications, such as blood thinners, may need to be paused. You will receive individualized pre-procedure instructions after clinical evaluation.
