Laboratory Technologist

A Medical Laboratory Technologist collects and analyzes a variety of biological and environmental samples, which helps the physician make a diagnosis and select a method of treatment.

The technology is divided into five major areas:

  • Clinical biochemistry: Which is the analysis of blood and body fluids
  • Haematology: The study of blood, which includes performing blood counts and studying cell types.
  • Clinical microbiology: Which involves culturing and identifying bacteria and other micro-organisms from specimens to detect infection
  • Immunohaematology, which involves typing blood for transfusion, and testing prenatal and postnatal screening for antibodies
  • Histotechnology: Which involves preparing tissue for microscopic examination.


The purpose of a Laboratory Technologist is to collect and analyze a variety of biological and environmental samples within the Laboratory in accordance with recognized international laboratory practices as well as the philosophy and objectives of the Authority, to ensure that medical and non-medical professionals have the test results necessary to diagnose, treat and manage disease in a timely and meaningful manner.

The Laboratory Technologist analyzes samples and conducts individual patient tests using both complex laboratory instrumentation and manual techniques. While performing analysis the incumbent must recognize normal and atypical findings and initiate the appropriate action. Accurate testing allows a referring physician to accurately diagnose medical conditions and arrange for proper care and treatment which ultimately impacts on a patients morbidity. This accurate and timely testing also assists public health to address regional or territorial health issues in an effective manner (i.e. TB, salmonella, MRO's).

Responsibilities of a Laboratory Technologist:

  1. Examines and analyzes a variety of biological samples using recognized international laboratory practices to ensure that medical and non-medical professionals have laboratory results required to diagnose, treat and manage disease.

  2. Performs, records, interprets and monitors Quality Control (QC) on all instruments and procedures to ensure the precision and accuracy of results reported.

  3. Collects and analyzes laboratory samples and performs diagnostic tests on patients as part of the health care team.

  4. Collect and prepare specimens for dispatch.

  5. Due to the absence of a local Pathologist, Laboratory Technologists will assist in the interpretation of results to medical and non-medical personnel, impacting on patient care and addressing Public Health Issues.

  6. Assists in the continued maintenance of complex laboratory equipment in order to minimize downtime and maintain productivity. This will aid in extending the life expectancy of the instruments thus avoiding costly repair and/or replacement.

Main Activities

  • Prepare and analyze samples using complex laboratory instrumentation and manual techniques.
  • Review, verify and release patient results through the Laboratory Information Systems (LIS) and notify the referring physician when abnormal patient results are found requiring immediate action.
  • Ensure all lab results are accurately entered into the LIS to track patient information.
  • Track stock items (laboratory products and supplies) used and notify the Supervisor when additional items are required and/or arrange for the ordering of the supplies when the Supervisor is unavailable.
  • Arrange for the shipping of sample which require special handling and ensure that the IRHSSA adheres to established National and International standards for the transportation of dangerous goods.
  • Conduct QC tests on all machines prior to analyzing samples.
  • Organizes, prioritizes and verifies the accuracy of patient/sample information prior to processing.
  • Calibrate or assist in the calibration of laboratory equipment on a scheduled or as needed basis.
  • Continually review test results to ensure that the findings are realistic and not compromised in any way.
  • Decide whether to release, delay or repeat testing prior to the reporting of patient results (reported results must be accurate).
  • Investigate abnormal results/trends and initiate corrective action.
  • Produce monthly reports for statistical purposes and review by the Technical Supervisor - Core Laboratory.
  • Run blood gas, capillary/venous gas tests, CBC, coagulation, chemistry and urinalysis tests.
  • Collects blood using a closed collection system (i.e. Vacutainer), needle with syringe, and/or micro-collection techniques following universal precautions.
  • Performs tests including but not limited to ECGs, WEA breath tests for H.pylori, sweat chloride collections, bleeding times, glucose tolerance testing following established standards of practice.
  • Collect specimens according to referral laboratory requirements.
  • Prepare specimens for shipping (centrifuge and separate serums).
  • Prepare shipping box according to IATA guidelines (follows special precautions for the transportation of dangerous goods where applicable).
  • Perform daily/weekly/monthly and as need maintenance.
