Unit Descriptor

Unit descriptor 

This unit of competency covers the ability to determine levels, function, activity and interactions of cellular and plasma components of blood using tests and procedures identified with the discipline of laboratory haematology.

Application of the Unit

Application of the unit 

This unit of competency is applicable to laboratory technicians and technical officers working in the biomedical industry sector. While this unit focuses on the laboratory investigation of human physiology and pathology, it reasonably describes aspects of work performed in veterinary settings. The unit of competency assumes that technical personnel would perform tests and procedures under close supervision. The results of their work would also normally be integrated, interpreted and reported on by supervising scientists and medical pathologists. Although a supervisor may not always be present, the technician will follow standard operating procedures (SOPs) that will clearly describe the scope of permitted practice in modifying testing procedures, interpretation of data and for communicating test results to people outside the laboratory. It is understood that the management of any laboratory would establish for itself, in terms of its own responsibility and purposes, the ability of any worker to work in a haematology laboratory, regardless of the education and training record or presumed ability of any worker.

Industry representatives have provided case studies to illustrate the practical application of this unit of competency and to show its relevance in a workplace setting. These can be found at the end of this unit of competency under the section 'This competency in practice'.

Overview of assessment 

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Assessors should ensure that candidates can:

  • count and measure cells
  • derive cell data that can assist with classification of cell populations
  • stain cells, identify their morphology and classify them
  • determine of the amount and function of blood components, such as haemoglobin and other substances quantified by spectrophotometry
  • measure clinically useful phenomena, such as erythrocyte sedimentation
  • assess haemostasis, coagulation, fibrinolysis and thrombosis
  • detect markers of immune response (where appropriate)
  • amplify and detect gene products (where appropriate)
  • contribute to the general maintenance of equipment and processes to ensure ongoing compliance with enterprise and laboratory accreditation
  • recognise problems in systems and documentation
  • use the enterprise information system efficiently
  • critically analyse information in enterprise documents
  • prepare documentation that is accurate, easily understood by the intended audience and in accordance with enterprise requirements
  • manage tasks and organise work to ensure the timely completion of tasks
  • use samples, reagents and materials economically and dispose of wastes safely
  • use equipment safely
  • maintain equipment, recording and reporting malfunctions appropriately.

Context of and specific resources for assessment 

This unit of competency is to be assessed in the workplace or simulated workplace environment.

This unit of competency may be assessed with:

  • MSL925001A Analyse data and report results 
  • MSL934002A Apply quality system and continuous improvement processes .

Resources may include:

  • standard haematology laboratory with relevant equipment, samples and reagents
  • enterprise procedures.

Under duty of care requirements, off-the-job training providers should ensure that blood samples are known to be antibody free for hepatitis B and C, syphilis and human immunodeficiency virus (HIV). However, this does not reduce the need for universal precautions in the use of these samples.

Method of assessment 

The following assessment methods are suggested:

  • review of results/data/records generated by the candidate
  • feedback from peers and supervisors that enterprise procedures were followed and that work is performed consistently in line with enterprise requirements
  • oral and/or written tests and paper problems associated with test methods and laboratory processes, such as equipment calibration and maintenance
  • integrated assessment by use of case studies to demonstrate performance of the range of tests and procedures implied in the critical aspects of competency and essential knowledge sections of this standard. Suitable case studies could involve:
  • performance of the routine full blood count, including the examination of the stained blood film
  • a coagulation screen, including tests to measure anti-vitamin K and anti-heparin therapeutic agents, and the counting of platelets
  • studies that can assist in identifying relationships between quantitative data from blood counts and morphological findings from stained blood films.

In all cases, practical assessment should be supported by questions to assess underpinning knowledge and those aspects of competency which are difficult to assess directly.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

Access must be provided to appropriate learning and/or assessment support when required.

The language, literacy and numeracy demands of assessment should not be greater than those required to undertake the unit of competency in a work like environment.

This competency in practice 

Industry representatives have provided the case study below to illustrate the practical application of this unit of competency and to show its relevance in a workplace setting.

Biomedical 

A patient's blood sample and request form have been brought to the laboratory. The patient has complained of rectal bleeding for some months. The technical officer has been asked by the supervisor to perform a full blood count on the analyser, set up an erythrocyte sedimentation rate, and to prepare, stain and examine a film of the patient's blood. The technical officer checks the records for information on the patient. Finding none, the technical officer records the required data in the laboratory information management system (LIMS) and then performs the required tests. Satisfied that the results of the standards are within range, the technical officer prints an interim report for the supervisor. The report incorporates the results of the differential white cell count, calculations of the leucocyte numbers and comments on the morphology of the blood cells. The report and film is taken to the pathologist for supplementary comments, verification and signature. Following these checks, the technical officer telephones the ward to advise that the patient's results can be retrieved from the ward's computer terminal.
