Blastomyces Antigen EIA

316

The MVista® Blastomyces Quantitative Antigen EIA aids in the diagnosis of blastomycosis. Monitoring the Blastomyces antigen also assists in therapeutic decision-making and identification of relapses.

• Quantitative Sandwich Enzyme Immunoassay (EIA)
• Serum and CSF are pre-treated to improve accuracy

Limitations

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

• Very High: Blastomyces, Histoplasma, Paracoccidioides and Talaromyces (talaromycosis, previously penicilliosis)
• Moderate: Coccidioides
• Rare: Aspergillus
• None: Cryptococcus

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

Testing is performed Monday – Saturday.

Results released: 24 – 48 hours

*New positives may require confirmation

None detected

Positive Below the Limit of Quantification: Results above the cutoff for positivity but below 0.2 ng/mL fall outside the linear range of the assay. These results are positive, but not accurately quantifiable. Result will be confirmed and reported the next business day.
Positive: 2 – 14.7 ng/mL
Positive Above the Limit of Quantification: Results greater than 14.7ng/mL fall outside the linear range of the assay. These results are positive, but not accurately quantifiable.

Specimen: Urine, Serum, Plasma, CSF, BAL
Container:
Serum: Collect serum specimens in serum separator tube. Allow blood to clot for 30 minutes, then centrifuge. Send in serum separator tube or pipette serum into a transport tube.
Plasma: Collect plasma specimens in an EDTA, heparin or sodium citrate tube. Centrifuge for 15 minutes and pipette plasma into a plastic screw cap vial.
Urine/CSF/BAL/Other Body Fluids: Submit urine, CSF, BAL and all other body fluids in a sterile screw cap container. Urine may be collected by cystocentesis or free catch in a sterile container.  Avoid collection of urine from the floor or cage enclosure.
