Requirements to the exam -
Students register for the exam via SIS for one of the 3 announced dates. Students can arrange another term with the examiner.

The exam will consist of elaboration of four individual tasks assigned during the semester and final oral examination. Assignments must be submitted in paper form to the specified extent not later than the oral examination. In addition to the discussion of two drawn topics, the test will also evaluate the correctness and performance of these tasks.


1. Main elements applied by analytical and medical laboratories to ensure the quality of analysis results (QA / QC).

2. Quality management systems in the laboratory. Accreditation according to EN ISO / IEC 17025, EN ISO 15189 ed. 2; certification according to ČSN EN ISO 9001; good laboratory practice and good manufacturing practice; their comparison and position in analytical and medical laboratory. The role of quality manager. Risk management. Controlled documentation.

3. Development and standardization of analytical method (procedure), use of standard procedure for routine analysis.

4. Validation - validated parameters, design of validation study. Verification.

5. Traceability of results of analytical measurements - measurement of substance quantities, primary methods, primary reference materials, specifics of metrological traceability in chemistry and biochemistry.

6. Reference materials (RM), types, RM certificate, use for individual types of analytical methods. Working RM, primary RM. Information security - international database RM. Commutability RM. Comparison of measured and certified CRM value.

7. Quality management, its goal. Series, quality management tools, control sample requirements.

8. Control charts. Purpose, principle, types. Construction of limits. Method of use.

9. Interlaboratory experiment. Types, purpose. Proficiency testing, PT program selection (database) and frequency of laboratory participation. Method of assessing proficiency testing.

10. Uncertainty of analytical results. Intended use. Error and uncertainty. Evaluation in A and B. Two basic approaches to estimating uncertainty of determination. Methodological procedure. Presentation of results.

11. Fundamentals of legal metrology. Categorization of gauges. Working gauges specified. Specifics of metrology in chemistry.

12. Instrumentation. Instrumentation calibration, instrumentation qualification. Metrological confirmation. Metrological support of analytical laboratory, metrological order.
