That\u2019s why it\u2019s important to talk with a doctor, preferably an asthma specialist, about your symptoms. Asthma specialists are board-certified allergists and pulmonologists who are familiar with asthma diagnosis and treatment guidelines.<\/p>\n\n\n\n<p>Like a skilled detective, your doctor will investigate and look for clues to determine the cause of your symptoms.&nbsp;These clues include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>your signs and symptoms<\/li>\n\n\n\n<li>medical history and family history<\/li>\n\n\n\n<li>physical exam<\/li>\n\n\n\n<li>lung function tests and other medical tests<\/li>\n<\/ul>\n\n\n\n<p>There is no single factor or test that confirms an asthma diagnosis.

class=\"wp-block-heading\">Tests Used to Diagnose Asthma<\/h2>\n\n\n\n<p>Your doctor has evaluated your health history and conducted a physical exam. If asthma is suspected to be the cause, then diagnostic tests are needed. Part of diagnosing asthma includes breathing tests or lung function tests (also called pulmonary function tests). These tests measure lung function.<\/p>\n\n\n\n<p>Your doctor may also perform allergy tests to determine if allergens are a possible trigger for asthma symptoms. They may also do additional tests to rule out other conditions. No single test is used to diagnose asthma, but each is a piece of the puzzle.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Spirometry Test<\/h3>\n\n\n\n<p>Spirometry is the most common type of pulmonary function test. You take a deep breath in and then breathe out as hard as you can into the machine. This is done using a device called a spirometer. A spirometer is a computerized device which checks how well your lungs are working. The spirometer shows how much air you can breathe in and out and how fast you did it over a certain time. The results will show whether your airways are inflamed, narrow or tight.<\/p>\n\n\n\n<p>You may do the test several times in one sitting. You might do it before and after using a quick-relief albuterol bronchodilator. Test results that improve after using the medication are a strong indicator of asthma.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"Learn About Spirometry: Taking a Lung Function Test\" width=\"720\" height=\"405\" src=\"https:\/\/www.youtube.com\/embed\/Zs8Fs5HaJHs?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Peak Expiratory Flow Test<\/h3>\n\n\n\n<p>A peak expiratory flow (PEF) test measures the speed of air flowing out of your lungs. Peak expiratory flow can be measured as part of spirometry. It can also be done using a handheld device called a peak flow meter (PFM).<\/p>\n\n\n\n<p>The test starts with taking a deep breath. You then blow forcefully into the device.&nbsp;The device measures the speed of air that you forcefully blow out.&nbsp;PEF tests are part of spirometry in a doctor\u2019s office, but you can use a PFM at home. Your doctor may want you to test at home to make sure your asthma treatment is working.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Methacholine Challenge Test<\/h3>\n\n\n\n<p>If you have no asthma symptoms on the day of your exam, the results of a lung function test may be normal. In this case, your doctor may order another test called a methacholine challenge. This is sometimes called a bronchoprovocation test.<\/p>\n\n\n\n<p>Methacholine is a medication. It causes a brief tightening of the airways that is more intense in people who have asthma.<\/p>\n\n\n\n<p>Methacholine challenge tests are done under the supervision of a doctor. You start by getting a baseline spirometry measurement.&nbsp;Then you inhale a small amount of methacholine and repeat the lung function tests. You take increasing doses of methacholine until a maximum dose is reached or you have a 20% drop in your lung function. If the test causes a decrease in lung function, you likely have an asthma diagnosis.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><a href=\"\/what-is-asthma\/how-is-asthma-diagnosed\/nitric-oxide-testing\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong><u>FeNO Test<\/u><\/strong><\/a><\/h3>\n\n\n\n<p>FeNO stands for fractional exhaled nitric oxide. Nitric oxide is a gas produced by the cells in your lung as a response to inflammation.&nbsp; A FeNO or exhaled nitric oxide test measures the amount of the gas in your lungs. Higher amounts of FeNO suggests high amounts of inflammation in the lungs.<\/p>\n\n\n\n<p>With this type of lung function test, you slowly and steadily breathe out into a handheld tube. As you breath out, the device measures the amount of gas in your breath.&nbsp;This will help your doctor measure inflammation in your lungs. Your doctor may repeat FeNO test at follow-up visits to look at signs of asthma control.<\/p>\n\n\n\n<p>FeNO tests can also help your doctor determine the best treatment for you.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n\n\n<style>.kadence-column19376172_1b3e93-6a > .kt-inside-inner-col{padding-top:20px;padding-bottom:20px;}.kadence-column19376172_1b3e93-6a > .kt-inside-inner-col,.kadence-column19376172_1b3e93-6a > .kt-inside-inner-col:before{border-top-left-radius:0px;border-top-right-radius:0px;border-bottom-right-radius:0px;border-bottom-left-radius:0px;}.kadence-column19376172_1b3e93-6a > .kt-inside-inner-col{column-gap:var(--global-kb-gap-sm, 1rem);}.kadence-column19376172_1b3e93-6a > .kt-inside-inner-col{flex-direction:column;}.kadence-column19376172_1b3e93-6a > .kt-inside-inner-col > .aligncenter{width:100%;}.kadence-column19376172_1b3e93-6a > .kt-inside-inner-col{background-color:var(--global-palette9, #ffffff);}.kadence-column19376172_1b3e93-6a > .kt-inside-inner-col:before{opacity:0.3;}.kadence-column19376172_1b3e93-6a{position:relative;}@media all and (max-width: 1024px){.kadence-column19376172_1b3e93-6a > .kt-inside-inner-col{flex-direction:column;}}@media all and (max-width: 767px){.kadence-column19376172_1b3e93-6a > .kt-inside-inner-col{flex-direction:column;}}<\/style>\n<div class=\"wp-block-kadence-column kadence-column19376172_1b3e93-6a\"><div class=\"kt-inside-inner-col\"><style>.kadence-column19376172_136dd6-78{max-width:800px;margin-left:auto;margin-right:auto;}.wp-block-kadence-column.kb-section-dir-horizontal:not(.kb-section-md-dir-vertical)>.kt-inside-inner-col>.kadence-column19376172_136dd6-78{-webkit-flex:0 1 800px;flex:0 1 800px;max-width:unset;margin-left:unset;margin-right:unset;}.kadence-column19376172_136dd6-78 > .kt-inside-inner-col,.kadence-column19376172_136dd6-78 > .kt-inside-inner-col:before{border-top-left-radius:0px;border-top-right-radius:0px;border-bottom-right-radius:0px;border-bottom-left-radius:0px;}.kadence-column19376172_136dd6-78 > .kt-inside-inner-col{column-gap:var(--global-kb-gap-sm, 1rem);}.kadence-column19376172_136dd6-78 > .kt-inside-inner-col{flex-direction:column;}.kadence-column19376172_136dd6-78 > .kt-inside-inner-col > .aligncenter{width:100%;}.kadence-column19376172_136dd6-78 > .kt-inside-inner-col:before{opacity:0.3;}.kadence-column19376172_136dd6-78{position:relative;}@media all and (min-width: 1025px){.wp-block-kadence-column.kb-section-dir-horizontal>.kt-inside-inner-col>.kadence-column19376172_136dd6-78{-webkit-flex:0 1 800px;flex:0 1 800px;max-width:unset;margin-left:unset;margin-right:unset;}}@media all and (max-width: 1024px){.kadence-column19376172_136dd6-78 > .kt-inside-inner-col{flex-direction:column;}}@media all and (max-width: 767px){.wp-block-kadence-column.kb-section-sm-dir-vertical:not(.kb-section-sm-dir-horizontal):not(.kb-section-sm-dir-specificity)>.kt-inside-inner-col>.kadence-column19376172_136dd6-78{max-width:800px;-webkit-flex:1;flex:1;margin-left:auto;margin-right:auto;}.kadence-column19376172_136dd6-78 > .kt-inside-inner-col{flex-direction:column;}}<\/style>\n<div class=\"wp-block-kadence-column kadence-column19376172_136dd6-78\"><div class=\"kt-inside-inner-col\"><style>.kb-image19376172_d42f7c-1d .kb-image-has-overlay:after{opacity:0.3;}<\/style>\n<figure class=\"wp-block-kadence-image kb-image19376172_d42f7c-1d size-large\"><img decoding=\"async\" width=\"1080\" height=\"572\" src=\"https:\/\/allergyasthmanetwork.org\/wp-content\/uploads\/2024\/10\/Black-doctor-consultation-with-patient-1080x572.jpg\" alt=\"A doctor wearing glasses and a white coat sits at a desk with a stethoscope around his neck, holding a medical instrument.

Some people may develop moderate persistent asthma or severe persistent asthma. It is estimated that 5-10% of people with asthma have <a target=\"_blank\" href=\"https:\/\/allergyasthmanetwork.org\/what-is-asthma\/what-is-severe-asthma\/\" rel=\"noreferrer noopener\"><strong>severe asthma<\/strong><\/a>.<\/p>\n\n\n\n<p>Moderate persistent asthma involves experiencing symptoms daily and more than one night per week. Severe persistent asthma involves symptoms throughout the day and most nights per week. Severe asthma patients may go to the emergency department or hospital often. They may be unable to go to work or school, or do simple activities, due to breathing problems.<\/p>\n\n\n\n<p>Some people may develop a subtype of asthma called <a href=\"https:\/\/eosasthma.org\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\"><strong>eosinophilic asthma<\/strong><\/a>. This is a severe form of asthma. Eosinophils are white blood cells. They fight infection but also cause inflammation. Research has shown a link between too many eosinophils in the blood and severity of asthma attacks. <a href=\"https:\/\/eosasthma.org\/diagnosis-treatment\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\"><strong>Diagnosis of eosinophilic asthma<\/strong><\/a> may involve blood tests, a sputum sample or a bronchial biopsy of fluid examination.<\/p>\n\n\n\n<p>It\u2019s important to

These include persistent cough, wheezing and shortness of breath.<\/p>\n\n\n\n<p>Asthma is usually diagnosed early in life. Diagnosis of asthma includes a physical exam, family history of allergic diseases and lung function tests. COPD tends to occur in people after the age of 40. It involves lung diseases, including emphysema and chronic bronchitis, that worsen over time. Symptoms include increased mucus or phlegm and respiratory tract infections. COPD is often the result of long-term, heavy cigarette smoking.<\/p>\n\n\n\n<p>Learn more<a href=\"\/news\/asthma-copd\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>about asthma, COPD,<\/strong><\/a> and when the two meet.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"Ask the Allergist: Is It Asthma or COPD?
