Module summary

This module will facilitate knowledge and understanding of routine laboratory tests, when to order them for patients and how to interpret the results with reference to the individual patient.

Module will run

Occurrence Teaching cycle
A Summer Term 2019-20

Module aims

The aim of this module is to extend existing understanding and knowledge of the purpose and limitations of laboratory tests. Students will develop an understanding of the commonly used laboratory investigations in order to decide when (and when not to) order laboratory tests for patients and be able to understand the results and implications for the patient. Students will explore how to integrate test results into the plan of care, including an understanding of the ethical and social implications of ordering tests and how to communicate test results to patients.

Module learning outcomes

By the end of the module students will be able, using evidence based practice:

  1. To appreciate the rationale for, and limitations of the use of laboratory investigations in clinical practice.
  2. To increase knowledge of commonly used laboratory tests, and how to interpret the results in the context of individual patients.
  3. To use knowledge gained through patient assessment in order to decide whether and which investigations should be ordered.
  4. To synthesize information gained from lab investigations and plan care accordingly.
  5. To consider the ethical and social implications that performing laboratory tests has on an individual, and be able to discuss these implications and the results with the patient.

Additional assessment information

Formative case studies as above will be in the same format as the summative exam. The summative assessment will be a 2 hour exam comprising of case studies requiring short answers which will test students' ability to interpret clinical information,their clinical decision making skills and communication. The pass mark will be 50%.
