Get a Pulmonary Function Test (PFT / Spirometry) at VRX Diagno Lounge, Goregaon West a non-invasive test that measures how much air you can inhale and exhale and how fast. Used to diagnose and monitor asthma, COPD, restrictive lung disease, and pre-operative lung assessment. Same-day report. Pre-bookable slots.
Pulmonary Function Test (Spirometry) measures lung volumes and flow rates as you breathe forcefully into a mouthpiece. It quantifies FEV1 (volume in 1 second), FVC (total forced volume), FEV1/FVC ratio, and other indices to detect obstructive (asthma, COPD), restrictive (fibrosis), or mixed lung diseases. A bronchodilator may be given mid-test to assess reversibility useful in diagnosing asthma.
Reduced FEV1/FVC with significant reversibility after bronchodilator
Reduced FEV1/FVC ratio (less than 70%) with limited reversibility
Reduced lung volumes (FVC) with normal/high ratio interstitial fibrosis, neuromuscular
Tracks improvement in FEV1 with inhalers and pulmonary rehabilitation
Workers exposed to dust, fumes, asbestos early detection of damage
Before chest, abdominal, or major surgery in smokers and respiratory patients
Especially with breathlessness on exertion for asthma/COPD diagnosis
Annual or 2-yearly screening for COPD
To monitor severity and treatment response
Mill workers, construction, mining, painting, welding periodic monitoring
Major chest/abdominal surgery in smokers or respiratory patients
Underlying lung disease workup
Spirometry from age 5–6 onwards is feasible
To check for associated lower-airway involvement
| Parameter | What It Measures | Reference Range |
|---|---|---|
| FEV1 | Volume exhaled in 1 second | Lab-reported predicted % |
| FVC | Total forced exhaled volume | Lab-reported predicted % |
| FEV1/FVC Ratio | Diagnoses obstruction | > 70% (normal) |
| PEF | Peak expiratory flow | Lab-reported |
| Bronchodilator Reversibility | > 12% & 200 mL increase = positive (asthma) | Asthma test |
| Severity Grading | Mild / Moderate / Severe / Very Severe | Based on % predicted |
Normal lung volumes, FEV1, and FEV1/FVC ratio above 70% suggest no significant obstructive or restrictive disease. Continue routine yearly screening if you have risk factors.
Reduced ratio = obstruction (asthma if reversible, COPD if not). Reduced volumes with normal ratio = restriction. Severity is graded by % predicted FEV1. Your physician will correlate with symptoms and history.
Every report is reviewed by an experienced pathologist with clear interpretation and clinical comment.

Truly appreciated the personal attention and professional approach during my aqua therapy sessions. The physiotherapist explained everything clearly. Highly recommended for anyone needing supervised pool-based rehab.
Started here after my knee surgery on my doctor's recommendation. The 1-on-1 sessions made a real difference and the team was supportive and patient throughout my recovery process. Worth every visit.
My mother has been visiting VRX Goregaon for arthritis-related sessions. The staff is patient, the centre is clean and well-maintained, and the pricing is transparent exactly what we were looking for.
Detailed initial consultation, no rushed appointments. The aqua therapy approach felt much gentler on my joints than regular gym workouts. Will continue here for the foreseeable future.
Easy to book, professional team, and a well-maintained therapy pool. I felt reassured by the close supervision throughout each session. Worth the visit if you need supervised aqua therapy in Mumbai.
Have visited multiple physio centres, but the depth of attention at VRX is genuinely different. They actually adapt the plan as you progress instead of giving everyone the same routine.
