Laboratories need a mechanism to determine possible causes of false results (e.g., personnel logs, lot numbers used). Practices should be evaluated to determine where changes can be made. Most episodes of false results are recognized only after a review of laboratory records, including genotyping results. Laboratories need a review process to detect false cultures earlier. 

 

Consequences of false positives which impact on clinical care of patients:

 

   1. Patients may be managed incorrectly in the following ways.

  • Unnecessary treatment and toxicity

  • Unnecessary isolation, hospitalization, and healthcare costs

  • Emotional repercussions to the patient

  • Unnecessary contact investigations

 

2. Credibility of the laboratory, hospital, or clinician may be questioned.

3. It May increase laboratory workload and testing costs.
