HISTOPLASMA QUANTITATIVE EIA TEST

310

87385

The MVista® histoplasma quantitative antigen test aids the diagnosis of histoplasmosis. Monitoring the histoplasmosis helps determine when treatment can be stopped and to diagnose relapse.

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

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.

• Serum:  Collect serum specimens in serum separator or red top tube. Allow blood to clot for 30 minutes, then centrifuge. Pipette serum into a plastic screw cap vial.
• 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 Fluid: Submit urine, CSF, BAL and all other body fluids in a sterile screw cap container.

• Serum/Plasma: 1.2 mL
• CSF: 0.8 mL
• Urine/ BAL/ Other Body Fluids: 0.5 mL

• Room Temperature: 2 weeks
• Refrigerated: 2 weeks
• Frozen: Indefinitely

• 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

Refrigerated/Frozen/Room Temperature

Ship next day service for Monday-Friday delivery

Testing is performed Monday-Friday

• Urine/BAL: Same day
• Serum/Plasma/CSF: 1 day

*New positives may require confirmation

None detected

• Positive: 0.20-20.00 ng/mL
• Positive 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.
