ABBOTT'S HIGH PERFORMING TESTING AT DECISIVE MOMENTS IN TRANSPLANT PATIENT CARE

 

 

CMV testing on the Alinity m system delivers accurate and timely viral load results, which helps clinicians guide patient care with confidence.

 

Improved Operational Efficiency
  • Alinity m is a continuous and random-access molecular analyzer with a time to first result of less than ~ 115 minutes that provides the ability to eliminate batching procedures and lead to improved laboratory workflow
  • Random access and STAT prioritization provide timely results that support clinicians in their decision to initiate and manage treatment effectively
Improved Confidence
  • Dual-target assay design helps provides robust, accurate and sensitive detection of Cytomegalovirus (CMV) from plasma or whole blood sample types
  • Assay is standardized to the 1st World Health Organization (WHO) International Standard for Human Cytomegalovirus for Nucleic Acid Amplification Techniques (NIBSC Code: 09/162)
  • Alinity m provides the ability to test Cytomegalovirus (CMV) and Epstein-Barr Virus (EBV) from a single plasma or whole blood sample, which is critical for transplant patients who are at risk of developing coinfections

CMV (Plasma)

The Alinity m CMV assay is an in vitro polymerase chain reaction (PCR) assay for use with the automated Alinity m System to detect and quantitate cytomegalovirus (CMV) DNA in human plasma. The Alinity m CMV assay is intended for use as an aid in the diagnosis and management of CMV in transplant patients and other immunocompromised patients. The assay is intended for use in conjunction with clinical presentation and other laboratory markers as an indicator of initiation of therapy and for use as an aid in monitoring viral response to antiviral treatment as measured by changes in CMV DNA levels in plasma. This assay is not intended to be used in screening blood, blood products, tissue or organ donors for CMV.

Limitations

  • Optimal performance of this test requires appropriate specimen collection and handling (refer to the SPECIMEN COLLECTION AND PREPARATION FOR ANALYSIS section of the package insert).
  • Human plasma (K2 EDTA, K3 EDTA, and PPT) specimens may be used with the Alinity m CMV assay. The use of other plasma tubes have not been evaluated.
  • Debris within plasma specimens (eg, fibrin strands) may interfere with sample processing.
  • The instruments and assay procedures reduce the risk of contamination by amplification product. However, nucleic acid contamination from the calibrators, positive controls, or specimens must be controlled by good laboratory practice and careful adherence to the procedures specified in the package insert.
  • If the CMV results are inconsistent with clinical evidence, additional testing is suggested to confirm the result.
  • A specimen with a result of “Not Detected” cannot be presumed to be negative for CMV DNA.
  • When serially monitoring the CMV viral load in patients, 1 specimen type should be used throughout the monitoring period. Follow institutional/society guidelines as appropriate.
  • Due to inherent differences between technologies, it is recommended that, prior to switching from one technology to the next, users perform method correlation studies in their laboratory to qualify technology differences. Users should follow their own specific policies/procedures.

CMV Whole Blood

The Alinity m CMV WB assay is an in vitro polymerase chain reaction (PCR) assay for use with the automated Alinity m System to detect and quantitate cytomegalovirus (CMV) DNA in human whole blood.

The Alinity m CMV WB assay is intended for use as an aid in the diagnosis and management of CMV in transplant patients and other immunocompromised patients. The assay is intended for use in conjunction with clinical presentation and other laboratory markers as an indicator of initiation of therapy and for use as an aid in monitoring viral response to antiviral treatment as measured by changes in CMV DNA levels in whole blood. This assay is not intended to be used in screening blood, blood products, tissue or organ donors for CMV.

Limitations

  • Optimal performance of this test requires appropriate specimen collection and handling (refer to the SPECIMEN COLLECTION AND PREPARATION FOR ANALYSIS section of the package insert).
  • Human whole blood (K2 EDTA or K3 EDTA) specimens may be used with the Alinity m CMV WB assay. The use of other specimen types or collection tubes has not been evaluated.
  • The instruments and assay procedures reduce the risk of contamination by amplification product. However, nucleic acid contamination from the calibrators, positive controls, or specimens must be controlled by good laboratory practice and careful adherence to the procedures specified in the package insert.
  • If the CMV results are inconsistent with clinical evidence, additional testing is suggested to confirm the result.
  • A specimen with a result of “Not Detected” cannot be presumed to be negative for CMV.
  • When serially monitoring the CMV viral load in patients, 1 specimen type should be used throughout the monitoring period. Follow institutional/society guidelines as appropriate. 
  • Due to inherent differences between technologies, it is recommended that, prior to switching from one technology to the next, users perform method correlation studies in their laboratory to qualify technology differences. Users should follow their own specific policies/procedures.
