  QUALITY ASSUARANCE(QA):- Quality assurancehas been defined by WHO as the total process whereby the quality of laboratory reports can be guaranteed. It has been summarized as the: right result, at the right time, on the right specimen , from the right patient, with the result interpretation based on correct reference data, and at the right price. QUALITY CONTROL(QC):- The term QC covers that part of QA, which primarily concerns the control of errors in the performance of tests and verification of test results. QC must cover all aspects of every procedure within the department. It must be practical, achievable, and affordable

  Standard operating procedures(SOPs)  to improve and maintain the quality of laboratory service to patients and identify problems associated with poor work performance .  to provide laboratory staff with written instructions on how to perform tests consistently to an acceptable standard in the laboratory . to help avoid short-cuts being taken when performing tests .  to provide written standardized techniques for use in the training of laboratory personnel .  to facilitate the preparation of a list and inventory of essential reagents, chemicals and equipment .  to promote safe laboratory practice

  Pre-Analytical Stage:- • SOPsneed to describe:- • Selection and appropriate use of microbiological investigations • Collection and transport of specimens. • How to fill in a request form correctly. • Check to be made when the specimen and request form reached the lab.
• 10.
  Analytical stage • Detailedprocedure for examining different specimens • Staining techniques and QC of stains • Aseptic technique and safe handling of infectious material. • Preparation and QC of culture media and preservation of stock stain • Inoculation of broth and agar culture media and its plating techniques. • Reading and interpretation of culture. • Technique to identify pathogen,AST, QC of procedure • Cleaning and QC of equipment used in microbiology • Safe work practice. • Disposal of specimen and culture • Cleaning of glassware,sterilization procedures.
• 11.
  Post analytical stage •Reporting and verifying of microbiological test results. • Taking appropriate actions when a result has serious patient or public health impactions. • Interpreting test report correctly.

  NATIONAL ACCREDITATION BOARDFOR TESTING CALIBRATION LABORATORIES(NABL) • Constituent board of Quality Council of India. • Follows SOPs for performing tests and adhere to set of quality guidelines.
• 14.
  National External QualityAssurance Scheme(NEQAS) • Main objective of an EQA scheme is to confirm that a lab SOPs and internal QC procedures are working satisfactorily. • WHO advice that EQA scheme should operate monthly or at least four times a year.
• 15.
  • Collection ofmicrobiological specimens • Type of specimen • Time of collection • Collection techniques • Labelling specimens • Specimens containing dangerous specimens • Preservatives and transport media for microbiological specimens • Transport of microbiologcal specimens collected in hospital

  Good clinical laboratorypractices Good Clinical Laboratory Practices (GCLP) deal with the organization, process and conditions under which laboratory studies are planned, performed, monitored, recorded and reported.
