Problem Scenario #1 You’re in the middle of performing ELISAs and the reader fails. You don’t have a documented procedure for troubleshooting, the maintenance log has not been updated for 2 years, and the manufacturer’s instructions are missing. What should you do? Why?

Functioning Equipment is Vital for:
Trainer’s Guide Module: Equipment Functioning Equipment is Vital for: Producing reliable test results Minimizing instrument breakdown Lowering repair costs Preventing delays in reporting test results Maintaining productivity Minimizing instrument breakdown that slows down the work, and reduce the number of costly services for instrument repair, through appropriate planning for maintenance and repair (Creates basis for improving selection and purchase policy) Reliable results aids clinical diagnosis. Unreliable results may result in incorrect diagnosis and treatment of the patient. If equipment is properly maintained, it is less likely to breakdown before its next service and is less likely to perform inadequately as a result of lack of maintenance.

A Good Equipment Program Achieves
Trainer’s Guide Module: Equipment A Good Equipment Program Achieves Maintaining a high level of performance Lengthening instrument life Reducing interruption of services due to breakdowns and failures Improving customer satisfaction Improving the technologist’s confidence and knowledge A good equipment program plays an important role in the quality assurance of a laboratory to be able to produce reliable results.
