Critical lab values assessment

Establishing lab clinical analysis values to be considered critical for the safety of the patient through a consensus.
Critical analysis results may expose a life-threatening pathological state of the patient if the right measures are not taken in a timely manner. Labs from all over the world have difficulties to determine such precise numbers.

The numerical imprecision in the literature when it comes to critical values and case studies is astonishing.

A number of specialists were consulted to establish which tests must be considered relevant.

Each critical number required a particular scale adapted to its units.

  • Develop a model with its scale and units for each critical value.
  • Design an extensive consensus tool able to facilitate an agile contribution of a heterogeneous group of experts.
