Mucoid Sputum has a white and dense consistency. Compared to usual sputum, this is a bit thicker and stickier partially because of an increased mucus production combined with pus. This is suggestive of a non-infectious airway disease (e.g. chronic bronchitis, asthma) or may also indicate an infection at its earliest stages like in early lobar pneumonia. Lung tumors and TB infection are also related most frequently with persistent production of mucoid sputum.
