Apart from basic tests of hematology, biochemistry and radiology Asthma Bhawan is equipped with following specialized testing facilities:
Test to measure obstruction in airways. Useful in Asthma, smoker’s lung disease COPD and ILD.
It measure diffusion of gases across alveolo-capillary membrane. Useful in assessment of ILD.
It measure airway resistance. Sensitive measure of severity of asthma.
Many people snore loudly and there is cessation of respiration for few seconds called apnea. Apnea episodes can lead to reduced oxygen in the body to cause a disease known as obstructive sleep apnea. It is usually a disease in obese patients. Symptoms include irritability, forgetfulness, morning headache and day time sleepiness. Untreated disease lead to occurrence of hypertension, stroke, heart attack and sudden death. Polysomnogram or sleep test records breathing, heart rate, oxygen saturation, EEG and leg movement during sleep to diagnose OSA. People with above symptoms should get themselves tested.
It is endoscopy of airways. It is useful in diagnosis of lung cancer or foreign body lungs.
When fluid is filled in the pleura it should be aspirated. Chemical analysis reveal causal factor of the disease. TB is most common cause of the disease.
Histamine Challenge Test
When patient of asthma is normal or in remission then histamine challenge test make diagnosis of asthma. Increasing dose of histamine is administered by nebulizer which causes contraction of airways in patients of asthma while in normal person airways does not contract.
Hypoxia Challenge Test
Patients of respiratory diseases when go to high altitude then they suffer from reduced level of oxygen in the body. This test can diagnose vulnerable people before hand so that trip to places of high altitude can be avoided or proper precautions can be kept.
Skin Prick Testing (SPT)
When allergic patient is exposed to an allergen, it can trigger the disease. SPT can make diagnosis of allergic trigger factors. Small amount of allergen is instilled in the skin and the site is observed after 10-15 minutes. If there is swelling and redness at that site it confirms the causal allergen. Patient should not be on many medicines including antiallergic medicine, antidepressant etc.
Drug Allergy Testing
Small amount of drug is injected in the skin and if weal and flare are formed allergy to that drug is suspected. It is very accurate for drugs such as penicillin but for other drugs it gives only a crude idea.
IGE Based Blood Allergy Testing
Though less accurate than SPT but in some conditions such as small children, in presence of skin diseases and patients on anti histamine treatment these provide an alternative.
Burchard Pollen Counter
This equipment catches environmental pollens and measures pollen load and types of pollen. It is a useful information of susceptible
