Regardless of the mode of delivery, represent a guide to the relative teaching time and student effort required to successfully achieve a particular competency/module. This may include not only scheduled classes or workplace visits but also the amount of effort required to undertake, evaluate and complete all assessment requirements, including any non-classroom activities.

Pre-requisites and Co-requisites

PMLTEST310A - Perform histological techniques.

Course Description

This unit of competency covers the ability to perform tests and procedures associated with processing and staining tissues for examination of tissue structure and abnormalities by pathologists and scientists to assist with disease diagnosis. The unit covers tests and procedures that are associated with anatomical pathology (including frozen sections), and may involve the use of automated processors and staining machines. The unit principally refers to techniques performed on human tissues, but many aspects may be relevant to animal and plant tissues.

Element:

Stain tissue sections

Performance Criteria:

1 Apply staining procedures to demonstrate required morphological features
2 Prepare labile reagents for immediate use
3 Select reagents for specified technique, ensuring reagent sequence matches standard procedure
4 Stain sections according to method accommodating any authorised variations and applying required quality control
5 Mount slides using medium compatible with staining technique
6 Examine sections microscopically to ensure expected staining outcomes are achieved and procedural artefacts are detected
7 Confirm macroscopically or microscopically that tissue type conforms with labelling and pathologist specifications
8 Participate in final check to establish that the number of slides tallies with the worksheet
9 Attach permanent label giving specimen details as required by enterprise

Other Information


Important information


Passing the course- Students must pass all of the assessment tasks listed above to pass the course.



Submission of work & late work- Students are required to submit work on the due date at the School Office using the cover sheets provided. The work will be accepted through the School Office and you will receive a receipt which you should keep as proof of submission. Students must NOT submit work directly to the teacher.

Late submission of work will incur a penalty of 5% of the maximum mark per day unless Special Consideration is applied for in writing using the required form. Marks can be deducted until the minimum pass mark is reached, after which no further marks will be deducted. Work will not be accepted more than 1 week after the due date.

Special Consideration- Any student who, because of illness or other circumstances beyond their control, has been prevented from attending a test, or whose performance in a test was affected by illness or other circumstances beyond their control may apply for Special Consideration. This must be done within 48 hours of the missed assessment/ assignment by lodging the appropriate form (available at the 6th floor office) with medical certificate or other supporting documentation at the Reception Office on Level 6, Building 51. Note: It is the policy of the School of Life and Physical Sciences NOT to AUTOMATICALLY PROVIDE SUPPLEMENTARY OR DEFERRED EXAMS. You will be advised of the outcome of your application for Special Consideration. The taking of Annual Leave does NOT constitute grounds for special consideration.

Attendance Requirements- Student must attend 80% of practical classes to pass. Practical exercises will be chosen for presentation as formal reports. If they are not satisfactory, you will be given an opportunity to resubmit. If you are absent from a session nominated for a formal report and you have applied for special consideration, it is your responsibility to negotiate a replacement report with the teacher. You MUST submit the number of required reports in order to pass the subject.

Plagiarism- Plagiarism is the presentation of the work, idea or creation of another person as though it is your own. It is a form of cheating and is a very serious academic offence that may lead to expulsion from the University. Plagiarised material can be drawn from, and presented in, written, graphic and visual form, including electronic data and oral presentation. Plagiarism occurs when the origin of the material used is not appropriately cited.
It also occurs through enabling plagiarism, which is the act of assisting or allowing another person to plagiarise or to copy your own work. Please make sure you consider this carefully in completing all your work and assessments in this course and if you are unsure about whether you might have plagiarised, seek help from your teacher.
