Q

Ix for suspected pneumonia

A

Bedside: flu swab, covid swab

Sputum culture

Consider urine culture– for pneumonoccus and legionella antigens

Bloods
o FBC (abnormal WCC)
o U&E (low Na+ esp with Legionella)
o LFT
o Blood culture
o ABG (assess pulmonary function)
o Blood film (RBC agglutination by mycoplasma caused by cold agglutinins)

CXR – lobar or patchy shadowing, pleural effusion, repeat 6-8 weeks later if abnormal, suspect underlying pathology e.g. lung cancer.

Atypical viral serology (increase antibody titers between acute and convalescent samples)

Bronchoscopy and broncheolaveolar lavage if pneumonia fails to resolve or clinically progresses
