Molecular Pathology in Infection Sciences (SLS202)

10 credits

Aim of this module

This module will provide the trainee with the knowledge and understanding of the molecular pathology of infection. In the work-based module they will be expected to apply this knowledge as they learn to perform molecular methods used in microbiology and gain experience of the interpretation of patient results in a variety of clinical settings.

  1. Interpret routine requests for molecular pathology investigations in microbiology in the correct clinical context and process the specimens that accompany those requests.
  2. Perform the range of basic laboratory techniques used in the workplace to investigate the molecular pathology of microbial infection.
  3. Apply the principles of internal quality control and external quality assessment and draw conclusions about assay performance.
  4. Use laboratory IT systems for handling, processing and storage of patient data and laboratory results. To include an introduction to bioinformatics.
  5. Produce a basic interpretive report on molecular laboratory results in the context of infection.

Important information

The academic parts of this module will be detailed and communicated to you by your university. Please contact them if you have questions regarding this module and its assessments. The module titles in your MSc may not be exactly identical to the work-based modules shown in the e-portfolio. Your modules will be aligned, however, to ensure that your academic and work-based learning are complimentary.
