Study population

The study seeks to enroll neonates (less than 1 month of age), pediatrics (between 1 month and 17 years of age) and adults (>18 years of age) who are suspected to have a blood stream infection (BSI /Sepsis).

Inclusion criteria

  • Male or female of neonates (less than 1 month of age), paediatrics (between 1 month and 17 years of age) or adults (≥18 years of age).
  • Admitted to ICU, Emergency Department, or other medical wards for acute illness with medical decision to perform blood culture for suspicion of bloodstream Infection.
  • Two additional EDTA blood sample/s collected from one anatomical site and at the same time as blood culture (two EDTA samples to be collected where possible).
  • EDTA blood volume is ≥1mL.
  • EDTA blood sample is stored according to Microbio's stability requirements.

Exclusion criteria

Exclusion Criteria:

  • No suspicion of blood stream infection (BSI).
  • Any inclusion criterion not met.
  • Multiple EDTA blood samples from the same patient.
  • EDTA blood sample not obtained from the same anatomical site and at the same time as the blood culture sample.
  • Subject has had an antimicrobial drug administered through the same port or central line as is used to collect the specimen.
  • EDTA blood samples that have not been stored according to Microbio's sample stability requirements.
  • EDTA blood volume \<1mL.

Interventions

  • Diagnostic testInfectID-BSI (Bloodstream Infection) qPCR Assay

    InfectID-BSI technology targets nucleic acid sequences unique to the target analyte. The qPCR raw data collected from InfectID-BSI's 9 assay tubes is analysed by Microbio's InfectID-Client (InfectID-BSI-associated software) and the result is reported as an analyte-detection if the unique target analyte is present or no result if the unique target analyte is absent. InfectID-BSI is carried out with whole blood from a venous puncture (EDTA). DNA is extracted from a sample of the collected blood using a validated DNA extraction instrument according to the manufacturer's instructions. The extracted DNA is then added to the InfectID-BSI qPCR reagent panel which consists of 9 reaction tubes (6 for bacteria, and 3 for yeast species). The panel is subjected to real-time qPCR using a process of Melt Curve analysis using the Rotor-Gene Q MDx qPCR instrument. The assay report identifies the species present in the sample upon completion. Results are generated within 3 hours.

What researchers measure

Primary outcomes

  1. Determine the sensitivity and specificity of InfectID-BSI versus blood culture.

    The objective of this study is to determine the sensitivity and specificity of the Microbio InfectID-BSI qPCR kit by the evaluation of clinical blood samples versus standard of care methods from blood culture.

    Time frame: Through study completion, an average of 1 year

  2. Determine the efficacy of detection and identification of the 26-pathogen panel in the InfectID-BSI assay versus standard of care blood culture. Using qPCR - a new molecular technology to identify the top 20 bacterial and 6 yeast sepsis causing species.

    The objective of the study is to determine the efficacy of the Microbio InfectID-BSI qPCR kit in a clinical laboratory environment using patient whole blood for pathogen detection and identification versus standard of care methods from blood culture. InfectID has it's own reporting software - InfectID-Client which is how the InfectID-BSI results will be reported for the study.

    Time frame: Through study completion, an average of 1 year
