26199 Histoplasma Antigen, Quantitative, CSF and BF (310)

Histoplasma Antigen, Quantitative, CSF and BF (310)
Test Code: HTAGCSO
Synonyms/Keywords

​Histoplasma Capsulatum QNT AG

Histoplasma, Quantitative EIA, CSF BF (310)​

FL HTAGCSO

Useful For

Aids the diagnosis of histoplasmosis

Monitor the response to therapy and determine when treatment can be stopped

Monitor Histoplasma antigen levels to help determine relapses of disease

Specimen Requirements
Specimen TypePreferred Container/TubeSpecimen Minimum Volume
(allows for 1 repeat)
​CSF​Sterile leak-proof container​0.8 mL
​Body Fluid​​Sterile leak-proof container​0.5 mL
​Bronchioalveolar Lavage (BAL)
​Sterile leak-proof container
​0.5 mL
Collection Processing Instructions

Submit specimen in sterile screw cap container.

Ship next day service for Monday - Friday delivery.

Specimen Stability Information
Specimen TypeTemperatureTime
​CSF/Body Fluid/BAL ​ ​​Ambient​14 days
Refrigerated (preferred)​​14 days
​Frozen​Indefinite
Rejection Criteria

If specimen is too viscous to pipette

Tissue, Sputum, Bronchial Brushings, Stool, FNA, Biopsy, Tracheal or Bone Marrow Aspirate

Stored in Transport Media, Fixative or Isolator Tubes

Interference

​The result is not intended to be used as the sole means for the clinical diagnosis or patient management decisions.

Cross-reactions are seen with blastomycosis, paracoccidioidomycosis, penicilliosis, less frequently in coccidioidomycosis, rarely in aspergillosis and possibly sporotrichosis.

Sputolysin, sodium hydroxide and potassium hydroxide treatment degrade the analyte detected in the assay.

Performing Laboratory Information
Performing LocationDay(s) Test PerformedAnalytical TimeMethodology/Instrumentation
​MiraVista Diagnostics​Monday through Friday​1 day

​Quantitative Sandwich Enzyme Immunoassay (EIA)

CSF is pre-treated to improve sensitivity which adds 1 day to TAT.

Reference Lab
Miravista Diagnostics
Test Information

Positive samples may require confirmation which could extend TAT.

Reference Range Information

None Detected

Interpretation

Reference Interval:  None Detected

Reportable Range:  Positive:  0.20 ng/mL to 20.00 ng/mL
  Positive results above 20.00 ng/mL are reported as "Above the Limit of Quantification"

Results greater than 20.00 ng/mL fall outside the linear range of the assay. These results are positive, but not accurately quantifiable.

Cross-reactions occur with blastomyces spp., Coccidioides spp., and Paracoccidioides brasiliensis
