IVD & Companion Diagnostic Test

Diagnostic tests improve patient management and allow better control of health costs. They are a public health interest.

Companion diagnostic testing allows selecting by predictive marker identification only patients likely to receive a benefit from a so-called targeted therapy.

WHITE-TILLET advises and assists you to:

  • Establish a development plan for:
    • Defining an analytical plan, the sensitivity and specificity of the tests;
    • Determining:
      • The predictive positive and negative values;
      • The Receiver Operating Characteristic (ROC) curve.
      • The Likelihood Ratio (LR);
  • To evaluate the clinical validity and clinical usefulness
  • The CE marking procedure
