A breathing test that measures how open your airways are — the test that confirms or rules out asthma and COPD. Takes about 40 minutes, same-day result, interpreted by a pulmonologist. $1,200 MXN.
Spirometry is the standard lung function test. You take a deep breath and blow out as hard and long as you can into a mouthpiece; the machine measures how much air you move and how fast. We repeat it after a bronchodilator (a quick-acting inhaler) and wait for it to take effect to see whether your airways open up — the key difference between asthma and COPD. It's painless, takes about 40 minutes in total, and you leave with a result the same day.
Start to finish, including the wait for the bronchodilator to take effect and the repeat test.
As a standalone test (≈US$65–75). +$600 MXN if added to a consultation. Elsewhere in Mexico City it typically runs $1,400–$1,500.
Interpreted by the pulmonologist to ATS/ERS criteria, with a clear plan.
Instructions and your results explained in English.
Avoid coffee or soft drinks for 4 hours and don't smoke for 1 hour before. Avoid a heavy meal 2 hours before. Wear loose clothing. If you use a rescue (short-acting) inhaler, hold it for 6–12 hours before if it's safe for you to do so — ask us if unsure. Bring a list or photo of your current inhalers.
