Detecting Infections Rapidly and Easily for Candidemia Trial - Part 2 (direcT2 Study) (direcT2)

May 23, 2014 updated by: T2 Biosystems

Prospective Collection and Testing of Un-Spiked and Candida-Spiked Fresh Whole Blood Specimens From Patients Who Have Been Referred For a Diagnostic Blood Culture

The purpose of this study is to validate clinical performance (i.e. estimated sensitivity and specificity) of the T2 Candida test on the T2 DX Instrument compared to blood culture results and/or known Candida positive status of prospectively collected and contrived (i.e. Candida-spiked) clinical specimens.

Conditions

Detailed Description

This study will prospectively collect and analyze whole blood T2 clinical research specimens and concomitant blood culture specimens from patients who have been referred for a blood culture per routine standard of care. Additional analysis of blinded, contrived (i.e. Candida spiked and un-spiked whole blood) specimens will be completed by study sites to augment the analysis of Candida positive blood specimens prospectively obtained from the study population.

The clinical performance of the T2 Candida test on the T2 Dx Instrument will be evaluated by calculating the:

  • Estimated clinical specificity of the T2Candida test results compared to Candida negative blood culture results in prospectively collected specimens, and the
  • Estimated sensitivity of the T2 Candida test results compared to the known Candida positive status or Candida positive blood culture status of contrived specimens that have been spiked at clinically relevant concentrations of the target organisms and, where detected, to Candida positive blood culture results in prospectively collected clinical specimens.

Description

Inclusion Criteria:

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Specificity
Time Frame: Up to 19 hours post blood collection
Estimated specificity of the T2Candida test will be examined by comparing T2Candida test results from prospectively collected T2 clinical specimens to blood culture results from specimens that are culture negative for Candida and which have been collected at the same time and from the same anatomical location as the T2 specimens.
Up to 19 hours post blood collection
Sensitivity
Time Frame: Up to 19 hours post blood collection
Estimated sensitivity of the T2Candida test will be examined by comparing T2Candida test results to the known Candida positive status or Candida positive blood culture status of contrived specimens that have been spiked at clinically relevant concentrations of the target organisms and, where detected, to blood culture results from specimens that are culture positive for Candida and which have been collected at the same time and from the same anatomical location as the T2 specimens.
Up to 19 hours post blood collection
