Clinical ChemistryPRECEPTORSHIP

OBJECTIVES

Purpose

The UTMB CLS student is required to meet cognitive (knowledge), psychomotor (skill) and affective (attitude) objectives of each preceptorship. This document outlines the cognitive and psychomotor objectives of the program. Cognitive goals are evaluated through the use of a quiz based on the study guide questions, which are based on these preceptorship objectives.

Preceptorship Objectives

Upon successful completion of this course, at a level of 70% the student will be able to:

GENERAL PROCEDURES / Objective met

  1. Use appropriate personal protective equipment at all times when working with patient samples.

  1. Locate all fire extinguishers, eye wash stations and safety showers.

  1. Locate Materials Safety Data Sheets, chemicals carcinogens list, and hazardous chemicals list.

Specimen Preparation
  1. Recognize unacceptable specimens and follow procedures required when such specimens are received.

  1. Collect or recognize and process without assistance appropriate specimens for testing.

  1. Separate, aliquot, label and distribute specimen according to laboratory standard operating procedure (SOP).

Reference Laboratory Send-Out
  1. Using reference laboratory procedure manuals, process specimens for transport.

Laboratory Information System (LIS)
  1. Use or observe LIS to enter patient demographic and laboratory results.

Quality Assurance
  1. Accurately and legible log in and maintain required records at all times.

  1. Pipette accurately at all times.

  1. Reconstitute control sera and standards with accuracy and reliability without direct supervision.

  1. Perform quality assurance procedures for each test analysis and consistently maintain required documentation.

  1. Evaluate quality control data, recognize out-of-control data and perform troubleshooting measures according to laboratory policies for all laboratory procedures.

  1. Apply Westgard rules to quality control decisions, recognize out-of-control situations, and perform actions outlined in the SOP when these situations occur.

  1. Determine and implement the course of action to be taken when delta checks are not correlated.

  1. Recognize test results that need to be checked by repeat testing and those that are beyond the limits of linearity and perform procedures as defined by SOP when these occur.

ReferenceRanges

1.Recognize reference ranges, therapeutic ranges, and critical values and perform procedures at all times that are required by the SOP when these occur.
