Synovasure® Microbial Identification

This test can be ordered as a stand-alone test option.

Description

The Synovasure® Microbial Identification (MID) Test is a qualitative in vitro diagnostic test intended for the early detection of microbial antigen in synovial fluid of patients experiencing joint pain and/or inflammation. The Synovasure® MID Test detects antigen from:

  • Staphylococcus species
  • Candida species
  • Enterococcus species
  • P. acnes 

The test results are intended to be used as an additional test to microbial culture and to detect the presence of an organism in culture negative specimens


 

Included In


 

Available in New York State?

No. This test is not available in New York State.

Organism Sensitivity1 Specificity1
Staphylococcus species 94.0% 99.0%
Enterococcus species 97.1% 99.5%
Candida species 90.0% 99.6%
C. acnes 93.2% 99.0%

  Additional Performance Considerations
  • Identifies >70% of organism species that cause PJI1
  • A 2023 clinical study showed the panel’s ability to detect a microorganism in >49% of culture-negative PJI samples2

Specimen Source(s)

Periprosthetic joint prior to implant removal (i.e. Hip or Knee). 

Note: Performance on specimens from other anatomic locations is not defined. Non-intraarticular joint fluid will be tested if Zimmer Biomet is participating in a clinical study.

Shipping Guidelines

Monday to Friday

Ship specimen the same day as aspiration

Saturday to Sunday

Place in refrigeration and ship specimen on Monday

Specimens are rejected for any of the below reasons:

1.  Specimen is outside stability range

2.  Specimen is not representative of synovial fluid (i.e. blood, urine, etc.)

3.  Specimen is aspirated from a location other than the intra-articular joint space

*Note: Non-synovial fluid or intra-articular joint specimens will be tested if associated with a Zimmer Biomet-approved clinical study.7

When submitting a specimen to CD Laboratories for this panel:

    • Do not use lavage, contrast or other foreign liquids to aspirate fluid
    • Ensure specimen is not overly hemolyzed
    • A completed requisition form is required with each specimen
    • A barcode label from the specimen transportation kit is required on the top of completed requisition
    • For Physician Accounts Only: Patient signature and insurance information are required
