Clerical erros usually occur due to carelessness or during transcription of records.
Organizational errors may occur due to heavy workload or personal difficulties of staff members.
Technical errors may be caused due to human factors or by poorly standardized techniques, reagents or equipment.

Investigations would often reveal a breakdown in quality assurance system and remedial action should be taken for each error detected.

Remedial action requires:

Investigation of the error
Reassessment of procedure, quality control, reagents & consummables and full documentation
Conclusion and recommendation
Reporting and action to be taken

Role of Training and Personnel Proficiency Testing

An adequate and competant staff Is the backbone of a quality laboratory. Most of the failures in quality are caused by human error, carelessness or ignorance and not by defective technology.

Usually the techniques are validated and well documented but staff validation is often ignored. As human factors are the most important variables in any procedure, training of staff and evaluation of training is of particular importance.

Training must be well-planned, relevant and on-going. The training protocol should be constantly assessed and updated when required. All new staff members should be oriented to the workplace.

All the staff members should have regular in service training and must be encouraged to attend formal courses, seminars, conferences, etc to update their knowledge.

All the personnel carrying out the test should follow the standard operating procedures. Periodic checking and reiview of results is another important step in a well-implemented quality assurance programme.

The technical staff should be trained to carry out the test with prescribed quality control measures. The accuracy and precision of the work done by each technologist should be validated periodically. The external quality assurance samples will also help in performance evaluation.
