What is Sputum Examination Routine?

Sputum examination routine is the most common test to detect respiratory tract disease caused by fungi or bacteria. Sputum is a combination of saliva and mucus. One can collect sputum by coughing or aspirating from the lower respiratory tract.

In a healthy person, sputum is transparent, and odorless. It contains water, proteins, carbohydrates, and mineral salts. However, in patients with respiratory diseases, sputum may contain blood, bacteria, and viruses, leading to a change in color.
