Tests could include:
-
Spirometry for bronchospasm with prolonged evaluation

Allergy testing may be helpful in identifying allergens in patients with persistent asthma. Common allergens include pet dander, dust mites, cockroach allergens, molds, and pollens.
|
 |
Skin changes, like dermatitis or eczema, are a clue that the patient has allergic problems. Inquiring about a family history of asthma or allergies can be a valuable indicator of asthma.
|
|
Medical diagnosis for asthma involves a complete physical checkup. One of the most important tests is the measurement of pulmonary(lung) function—the volume of air a patient can inhale(breathe in) and exhale(breathe out).
|
 |
The first stage of asthma diagnosis is from a history of asthmatic symptoms. These symptoms include periods of coughing, wheezing, shortness of breath, or chest tightness that come on suddenly in response to specific stimulants or time periods.
|
|
Early diagnosis is critical to proper asthma treatment and management. Asthma may be diagnosed by the child's primary pediatrician or an asthma specialist, such as an allergist.The diagnosis of asthma may be strongly suggested when the typical sym...

During a physical examination, a health care provider studies a patient''s body to determine the presence or absence of physical problems.

The peak expiratory flow rate measures how fast a person can breathe out(exhale) air. It is one of many tests that measure how well your airways work.This test requires a peak expiratory flow monitor: a small handheld device with a mouthpiece at o...

Spirometry is the measurement of airflow into and out of the lungs. The patient is given instructions on how to perform the breathing maneuvers.

Pulmonary function tests are a group of tests that measure how well the lungs take in and release air and how well they move oxygen into the blood.In a spirometry test, you breathe into a mouthpiece that is connected to an instrument called a spir...

Pulmonary function tests are a group of procedures that measure the function of the lungs, revealing problems in the way a patient breathes. The tests can determine the cause of shortness of breath and may help confirm lung diseases, such as asthm...

This test tells how much air moves in and out of your lungs when you exercise. During the test, you may be asked to walk on a treadmill or ride on a stationary bike. The test may locate where your breathing problems begin. They may begin in the lungs, the heart, or both. Your test results can also show a safe activity level for you.
|
|
Normal individuals have a large reserve in lung function that allows breathing capacity to increase at least twenty to thirty times during periods of vigorous physical activity. It is not the ability to breathe that normally limits maximum exercis...
|
|
Each time you blow into your peak flow meter, you get a number. The number tells you what zone you're in: green, yellow, or red. When you take your peak flow and find your zone, do what your action plan tells you to do.
|
|
Monitoring your peak flow can help tell you how open your airways are—even before you have symptoms. It's done with a device called a peak flow meter. Your peak flow is how fast you can push air out of your lungs at any one time.
|
|
You and your health care provider can use information from a peak-flow meter to help stop a flare-up in its tracks.

A chest x-ray is an x-ray of the chest, lungs, heart, large arteries, ribs, and diaphragm.Chest radiography; Serial chest x-ray; X-ray- chest.The test is performed in a hospital radiology department or in the health care provider''s office by an x-...

A chest x ray is a procedure used to evaluate organs and structures within the chest for symptoms of disease. Chest x rays include views of the lungs, heart, small portions of the gastrointestinal tract, thyroid gland and the bones of the chest ar...

Detailed information on chest x-rays, including reasons for the procedure X-rays are made by using low levels of external radiation to produce images of the body, the organs, and other internal structures for diagnostic purposes. X-rays pass through body structures onto specially treated plates (similar to camera film) and a "negative" type picture is made. The more solid a structure is, the whiter it appears on the film. For this reason, bones appear very white on an x-ray film, but less dense tissue such as muscle, blood, skin, and fat appears darker.

Blood gases is a measurement of how much oxygen and carbon dioxide is in your blood. It also determines the acidity(pH) of your blood.Usually, blood is taken from an artery.
|
 |
Blood gas analysis, also called arterial blood gas(ABG) analysis, is a procedure to measure the partial pressure of oxygen(O 2) and carbon dioxide(CO 2) gases and the pH(hydrogen ion concentration) in arterial blood.Blood gas analysis is used to d...

Blood gases are defined as the mixture of gases, including oxygen(O 2), carbon dioxide(CO 2), and nitrogen(N 2), dissolved in the fluid fraction of blood.Oxygen from the air is transported from the lungs to all tissues of the body, where it is nee...

A pulmonary function test shows how well your lungs are working. A complete test has three parts. You may be given the entire test or only certain parts. The entire test is painless and lasts 45–90 minutes.

|
Allergy tests may be of two general types. In vivo tests that measure the immune response to an agent called an allergen that induces an allergic(atopic) reaction, and in vitro tests that measure the antibodies that mediate an allergic response.
