Diagnosis of Asthma
Diagnosis of asthma is mostly clinical. Some investigations to assess the extent of asthma and association of other conditions is usually called for in most cases. A detailed medical history and physical examination are done to assess the presence or severity of the following symptoms.
- Recurrent respiratory infections
- An allergic cough worse at night
- Sudden onset of wheezing and shortness of breath when exposed to allergens
- Your family history of asthma and allergies
- Medicines you may have used to help your breathing
A physical examination of your respiratory system and a general examination is done to rule out other illness.
After medical history and examination, pulmonary function test and other investigations may be included to complete the diagnosis
Clinical Tests include:
Pulmonary function test:
- Spirometry
- Challenge test
- Exhaled Nitric oxide test
- Complete Blood count
- Chest and Sinus X-rays
- CT scan (not done routinely)
- GERD assessment test (if associated gastric symptoms)
