PCP diagnosis typically involves a combination of clinical assessment, radiological imaging, and laboratory tests. Chest X-rays and CT scans can reveal infiltration patterns indicative of PCP. Laboratory tests may include:
Microscopic examination of induced sputum samples, bronchoalveolar lavage (BAL) fluid, or tissue biopsies Polymerase chain reaction (PCR) assays to detect Pneumocystis DNA Staining techniques such as Giemsa, Gomori methenamine silver, or direct fluorescent antibody staining
