Physical examination will give a clear indication of symptoms of asthma to most specialist doctors. The asthma specialist will focus on your skin, eyes, ears, nose, throat, and chest. The doctor will look at your skin for signs of eczema or hives. Inflammation in the ears or eyes may signify an underlying allergy. Dark circles under the eyes, called allergic shiners, and swelling in the nose are signs of allergic rhinitis, or hay fever, which is often associated with asthma.

The chest exam is the most important part of the asthma specialist’s physical examination. The doctor will rely on a stethoscope to detect wheezing and gauge the rate of air movement in and out of your chest. The doctor will ask the patient to take a deep breath or briefly exercise to make it easier for him to detect wheezing. An asthma specialist can often diagnose asthma by just looking at a patient’s chest. When patients with chronic asthma constantly use their chest and rib muscles to move air in and out of their lungs, the chest wall is stretched to the limit, and it expands, giving the chest a barrel-like shape.

Laboratory testing can also give a clear indication for asthma. Common tests include a nasal or sputum in which mucus from the nose or chest is examined under a microscope for an excess amount of white blood cells known as eosinophils. These Eosinophils are the indication of asthma or an ongoing allergic reaction, and they are found in excess amounts in those afflicted with hay fever and asthma.. Eosinophils normally comprise around 4 per¬cent of all white blood cells, but in patients with asthma the eosinophil blood count is frequently elevated. Another, though not a common ailment that mimic most symptoms of asthma is cystic fibrosis. The sweat test in infants can give the indication of cystic fibrosis.

Another major blood test in the diagnosis of asthma is the Immunoglobulin E or IgE test, which measures the amount of allergic or IgE antibody in a person’s serum or body. A high IgE level indicates that allergies may be causing the asthma. If the IgE level count is less than 32 the patient may not be having allergic asthma. IgE count of above 50 shows clear propensity to allergic asthma.
