Objectives

To know the underlying fundamentals and main steps of the diagnostic strategy in the areas of Clinical Pathology, Imaging and Medical Microbiology

 Specific objectives of Clinical Pathology

- Evaluate the interest of the most frequently available and / or requested laboratory tests.

- Evaluate the importance of sampling conditions as part of ensuring quality and accuracy of results.

- Describe problems of laboratory tests related to quality control, reference values, sensitivity, specificity and predictive value

 Specific objectives of Imaging

- Knowledge of the basic principles of different imaging techniques and their indications

 Specific Objectives of Medical Microbiology

- knowledge of the diagnostic strategy in the main syndromes / clinical pictures of infectious etiology.

- Know how to correctly select the different methods / diagnostic tests in Medical Microbiologye values, and the meaning of SI units of measurement.

Clinical Pathology
Lectures (5 hours)
The characteristics of the laboratory tests.
The value of the laboratory test. The sensitivity and specificity of a test. The importance of the prevalence of disease in the choice of tests and in the determination of the predictive value of a result. The meaning of the reference ranges. Screening, diagnosis and monitoring tests.
Biological Variability
Pre-analytical variability (fasting, exercise, posture, etc). Analytical variability. The individual variability. The relationship between physiological variations and the valorisation of a single result.

Practical (4 hours - 2 hours each session with small groups of students)
1. Blood sample collection
The conditions of the patient. The choice of tubes and the anticoagulants. Identification and conservation of samples. The technique of venipuncture. Realization of venous puncture in simulation laboratory.
2- The Lab Report
Requests and how they can influence prescribing. Evaluation and discussion of analytical reports with different pathologies. Sources of laboratory errors and ways to avoid them. Reference ranges and the critical values.
