53
Q

diagnostic tests:

A
  • fungal culture
  • Ag detection by enzyme immunoassay ; using serum or urine, but can be used for bronchoalveolar lavage (BAL) fluid or CSF (cross reactions can occur but + result can help guide diagnosis.
  • Fungal stains on cytological or histopathologic samples: Sputum, BAL, Lung biopsy or other tissue sample (False - can occur)
  • antibody tests: immunodiffusion and complement fixation tests (have low sensitivity and specificity therefore not reliable)
  • PCR : to confirm culture and histopathologic samples.
