Bronchoscopy is an endoscopic technique of visualizing the inside of the airways for diagnostic and therapeutic purposes. An instrument ( bronchoscope ) is inserted into the airways, usually through the nose or mouth, or occasionally through a tracheostomy .
Patients who require hospitalization will also receive blood tests, including to assess whether the infection has spread through their bloodstream. The treatment depends on the type of organism ...
Blood cultures should be performed in patients with symptoms, signs, or laboratory abnormalities compatible with mycobacterium infection. Blood cultures are not routinely recommended for asymptomatic persons, even for those who have CD4+ T-lymphocyte counts less than 100 cells/uL. [14]

Sometimes hemoptysis may be rust-colored. [citation needed] Lung cancer, including both non-small cell lung carcinoma and small cell lung carcinoma ...

[1] The detection of microbes in the blood (most commonly accomplished by blood cultures [2]) is always abnormal. A bloodstream infection is different from sepsis, which is characterized by severe inflammatory or immune responses of the host organism to ...
Primarily white blood cells, mainly mononuclear cells, generate the inflammation. [60] As well as damaging the lungs, many viruses simultaneously affect other organs and thus disrupt other body functions. Viruses also make the body more susceptible to bacterial infections; in this way, bacterial pneumonia can occur at the same time as viral ...
Story at a glance Screening for cancer can take a long time, depending on the necessary tests. Biopsies may be necessary for diagnosis, such as for lung cancer. Robotic-assisted bronchoscopy is a ...
Bronchoalveolar lavage (BAL), also known as bronchoalveolar washing, is a diagnostic method of the lower respiratory system in which a bronchoscope is passed through the mouth or nose into an appropriate airway in the lungs, with a measured amount of fluid introduced and then collected for examination.
