Unit of Competency | MSL975004A - Perform chemical pathology tests |
---|---|---|---|
Description | This unit of competency covers the ability to perform tests and procedures associated with the detection and monitoring of tissue and bodily fluid responses to normal physiological processes and disease through the identification and quantifying of chemical components. It covers tests and procedures that are usually associated with the discipline of clinical biochemistry. | ||
Employability Skills | This unit contains employability skills. | ||
Learning Outcomes and Application | The unit of competency is applicable to laboratory technicians working in the biomedical industry sector. The unit principally refers to human pathology but many aspects are relevant to veterinary pathology. This unit of competency describes the testing of tissues, blood, bodily fluids (cerebrospinal fluid, peritoneal and wound aspirates, sweat and sputum), calculi, and excreta (urine and faeces) in laboratories. Tests examine and measure compounds that can give information about alterations in individual physiology and pathology, or compounds, such as therapeutic drugs or drugs of abuse that will alter normal physiology. The tests are performed in a full or partial computerised and automated environment where large numbers of samples must be managed, analysed and their results recorded. This unit of competency assumes that the technical officer would perform tests and procedures under the close supervision of scientific and/or medical staff. Although a supervisor may not always be present, the technical worker will follow standard operating procedures (SOPs) that clearly describe the scope of permitted practice in modifying testing procedures, interpretation of data and for communicating test results to people outside the laboratory.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'. | ||

Evidence Required
List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. | |
Overview of assessment | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessors should ensure that candidates can: identify chemical substances that are associated with organ dysfunction or are indications of success or failure of treatment test for biological activity (e.g. assessment of enzyme activity indicative of organ/tissue damage) monitor humoral immune system components apply DNA techniques test for evidence of prior exposure to infective agents, as in the case of identifying plasma changes that are consequent to or associated with immune responses discriminate between significant data and artefact use the enterprise information system efficiently (e.g. networks or ordering for consumable materials) critically analyse information or documents and respond appropriately to an abnormal result prepare documentation that is accurate, concise and in accordance with enterprise requirements use samples, reagents and materials correctly and economically dispose of wastes safely communicate appropriately with a diverse range of internal and/or external customers reportequipment malfunction or liaise with contracted service technician to ensure equipment downtime is minimised. |
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: MSL9314002A Apply quality system and continuous improvement processes. Resources may include: enterprise documents, standard chemical pathology laboratory with relevant equipment, samples and reagents enterprise procedures, test methods and equipment manuals. 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), but this does not preclude the use of universal precaution in the use of blood samples. |
Method of assessment | The following assessment methods are suggested: review of results/data/records generated by the candidate feedback from peers and supervisors to confirm that enterprise procedures are consistently followed and that results meet enterprise requirements oral and/or written questions associated with laboratory determinations and record keeping integrated assessment with a case focus, such as the measurement of single or multiple chemical substances and metabolites in serum or other bodily fluids. 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 sample has been recorded in the laboratory's log as 'urgent cardiac enzymes'. The specimen has been processed ahead of the other routine samples. The technical officer selects the panel of tests in the cluster designated cardiac enzymes on the automated analyser. The technical officer also ensures that the instrument has adequate reagents, quality control sera and reference sera loaded before placing the sample for analysis. At the end of the analysis cycle, the quality control is validated and the result report generated. An elevated troponin is noted. The technical officer alerts the supervisor and confirms that this result can be phoned through to the requesting physician. The rest of the sample is refrigerated awaiting immediate follow-up tests. Within 24 hours, it will be frozen for a week in case more tests are requested. At the end of the day, the technical officer sets the analyser on standby, stows sensitive reagents in the refrigerator, cleans his/ her work area, and safely disposes of biological and non-biological wastes. |

Assessment Tasks
Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
