Lung Diseases Diagnosis

Blood tests can detect lung problems by measuring the levels of certain markers in the blood. Some blood tests used to diagnose lung problems include arterial blood gas test, complete blood count (CBC), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR).

Type 4 lung disease, also known as cell-mediated or delayed hypersensitivity pneumonitis, is a lung condition that occurs when the immune system responds abnormally to inhaled particles, leading to inflammation and damage in the lungs.

While an electrocardiogram (ECG or EKG) primarily measures the electrical activity of the heart, it can sometimes provide indirect information about lung problems. For example, a condition called pulmonary embolism, which is a blockage of the pulmonary artery in the lungs, can cause changes in the ECG that suggest heart strain or damage.

There are several types of devices available that can be used to measure lung function at home, such as peak flow meters and spirometers. However, it is important to note that these devices may not be as accurate as the tests performed in a medical facility and should not be used as a substitute for professional medical advice and care.
