This article will describe those tests so you are better prepared for a doctor visit.

Before your doctor orders more tests, however, he or she will get a more thorough picture of the times you experience respiratory problems or chest tightness. They will probably ask whether these symptoms at certain times of the year, how often, and what seems to trigger them. They will also want to talk about the history of your family – related to both asthma and allergies, as the two often occur together

physical exam is next performed to determine if there are noticeable signs of asthma that affect the airways .. This is quite simple. Your doctor will listen to what wheezing sounds in the chest with a stethoscope. And they may look for any signs of skin reactions. To confirm the diagnosis after all this, they will order a lung function test.

There are three primary lung function tests the doctor ordered. They are spirometry test, a challenge test and peak expiratory flow test. The spirometry test is usually the first port of call. It is a simple test that measures how much air you can blow out of your lungs after taking a deep breath in, as well as how fast the exhale is. The results appear lower than normal if there is inflammation of the airways -. A sign of asthma

The challenge test is a variation of the above. But instead of simply inhaling and exhaling normally, you inhale the first substance that causes the airways of asthmatics to narrow. The content that you inhale is called methacholine challenge and a test designed to expose you to triggers that usually affect asthmatics. Consequently, you can only breathe cold air, or do some vigorous exercise (some people get asthma from exercise). The spiro meter measures the outbreath. A normal reading means it’s doubtful you have asthma.

peak flow test may be done in place spiro meter test, although it is not as accurate. A peak flow meter is a portable device that measures how fast you can exhale air. The advantage of peak flow test is that it can be done at home, giving a series of readings over a period of time. This can be particularly useful when other tests were inconclusive or negative.

Whether your doctor uses one or a combination of tests, he will always take the family, so it’s a good idea to be prepared for it.
