HISTOPLASMA/BLASTOMYCES ANTIGEN RESULT
Not Detected
HISTOPLASMA/BLASTOMYCES ANTIGEN VALUE
Not Detected: 0.0 ng/mL
Not detected:
No antigen from Histoplasma or Blastomyces detected. False-negative results may occur depending on extent of disease or site of infection. Repeat testing on a new specimen if clinically indicated.
Detected:
Antigen from Histoplasma or Blastomyces (unable to differentiate) was detected, below the limit of quantification (<1.3 ng/mL). Result should be correlated with clinical presentation, exposure history, and other diagnostic procedures, including culture, serology, histopathology, and radiographic findings to aid in the differentiation between histoplasmosis or blastomycosis.
Detected:
Antigen from Histoplasma or Blastomyces (unable to differentiate) detected. Result should be correlated with clinical presentation, exposure history, and other diagnostic procedures, including culture, serology, histopathology, and radiographic findings, to aid in the differentiation between histoplasmosis and blastomycosis.
Detected:
Antigen from Histoplasma or Blastomyces (unable to differentiate) detected, above the limit of quantification (>20.0 ng/mL). Result should be correlated with clinical presentation, exposure history, and other diagnostic procedures, including culture, serology, histopathology, and radiographic findings, to aid in the differentiation between histoplasmosis or blastomycosis.
Due to significant cross-reactivity between galactomannan antigens from Blastomyces and Histoplasma, this assay does not differentiate between these 2 dimorphic fungal agents. To differentiate, consider fungal culture, molecular testing, or serology testing.
Positive results should be correlated with other clinical and laboratory findings (eg, culture, serology).
Low-level positive antigen levels may persist following resolution of infection and completion of appropriate treatment regimen.
Sensitivity of this assay to detect antigen from species other than Blastomyces dermatitidis or Histoplasma capsulatum is unknown.
False-positive results may occur less frequently with other dimorphic agents (eg, Coccidioides).
