Does A Normal Spirometry Rule Out Asthma
No, but less severe: Normal spirometry is the usual finding with intermittent & mild persistent asthma - at least when symptoms of asthma are not present. Spirometry can still be useful to diagnose asthma in these situations. A significant increase in lung function within the normal range after inhaling albuterol is associated with asthma. You can also provoke asthma using methacholine measuring the effect with spiro. ...Read moreSee 3 more doctor answers
Pulmonary function tests is a term used to describe a group of tests done to determine lung function. Spirometry measures the amount of air that can be taken in as well as the flow rate of forcefully exhaled air. A graph is generated and can be used to determine lung function. Likewise lung volumes and diffusing capacity determine the capacity as well as ...Read more
Can a person with no family history develop asthma at the age of 16 and spirometry results are normal?
Can a person with no family history develop asthma at the age of 16 if he has all asthmatic symptoms. But spirometry is normal?
Very but..: Asthma is an intermittent disease, thus a relatively normal lung function test on one occasion does not rule out asthma. However it should be abnormal when you have symptoms and the numbers (fev-1) often improves after bronchodilator. As with all tests, a doctor can only make a diagnosis after having obtained your history, performed a physical exam, and then interpret the lung function results. ...Read more
Maybe: Asthma occurs when people have excessive bronchospasm triggered by allergens, irritants, some medications or environmental exposures. Bronchospasm is typically acute and may not show up on spirometry if there has not been a recent trigger. In this case a methacholine challenge may be used to induce bronchospasm for diagnosis by spirometry. ...Read more
Why would I do worse on spirometry test after taking my inhaler? Possibilities if it's not asthma? I'm young female, never smoked.
Check with your doc: Probably a technical thing. But better check with your lung doc. ...Read more
Raising the shoulders helps me breath easier. Why is this? And if my shoulders were raised during a spirometry, would it hide a condition like Asthma?
If you have exercise induced asthma and have a spirometry test, will it most likely show on the results?
Doc says I've chronic bronchitis but I have no cough or sputum production my full pred. Value spirometry was 83% could it be late onset asthma?
PFT report: If you have a copy of the report, I think it is a good idea to review it with your physician. The interpretation takes into account more than one airflow value. If you have a chronic cough and reflux, then also consider aspiration and bronchoconstriction as a cause. ...Read moreSee 1 more doctor answer
No cough or sputum but I have a wheeze and tight chest. Pred. Value spirometry is 83%. Is this COPD or late onset asthma?
More information pls: COPD patients typically will produce more sputum or mucus when they cough. Your symptoms may be either but without a history of smoking, asthma is more likely. Since you have had a PFT, asking for the FEV1/FVC ratio will help your physician determine whether there is a component of restriction as well. ...Read moreSee 2 more doctor answers
Many things: Though "failing" is not a term I would use, there are many other conditions that can show up in a spirometry test. These may include lung obstructions, vocal cord dysfunction, copd, etc. Most of the time these conditions will give results that are not characteristically like asthma but feel like it. Good luck. ...Read more
Is it safe to use an incentive spirometer everyday if you have asthma? Does it help your lungs if you use it daily?
Peak Flows: Measuring your peak flows with an incentive spirometer at home is a great and safe way for you and your doctor to monitor your asthma over time. Occasional pulmonary function testing in the office provides valuable information, but tracking peak flows over times also lets us know how well controlled your asthma is. If you want to improve lung function try exercising 4-5 times per week. ...Read moreSee 1 more doctor answer

How accurate is a pulmonary function test that's testing for Asthma? Mine came back normal. Could I still possibly have asthma?
Short answer is: Yes: You may have a mild form with little exacerbation but a reactive airway disease is present. If there are no exacerbations, no treatment is necessary, ...Read more
If pulmonary function test shows a mild obstructive ventilatory defect with normal volumes and high dlco but not a smoker and don't have asthma, is this finding significant?
Need more info: You don't mention why you had pfts in the first place. The combination of a mild obstructive defect with normal volumes and high diffusion is typical of asthma. Without clinical data I can't be more specific. People with allergic rhinitis may have sub-clinical asthma. Which form of Hydrocortisone are you taking? Tablets? Topical? ...Read moreSee 2 more doctor answers
Nearly essential: Asthma is not one illness, but several processes that appear in greater or lesser degrees in any one affected individual. Together they can lead to the functional problems we recognize as asthma. Pulmonary function tests measure air flow and volumes; accurately performed PFT's are indispensable in the diagnosis and management of asthma and COPD. ...Read moreSee 1 more doctor answer
I had a pulmonary function test. I was curious and wondering can someone be accidentally diagnosed with asthma?
Hard to say: A lot of what is labeled as asthma may not turn out to be over the long run. Most true asthmatics have some related diagnosis in early childhood, males before one and females by three. Yet I have seen a 16 yo female with her first event. Many teens have transient exercised triggered wheezing, which is less worrisome and often fades with age. You can always under-perform on function tests. ...Read more
Piece of Puzzle...: A pulmonary function test alone cannot tell a doctor if you have asthma. This test can be very useful but is used in conjunction with other important information including a detailed past medical history and physical exam. Both subjective and objective measures are used to determine if you have asthma or any other respiratory disease. ...Read more
