Why I Chose the Medical Laboratory Profession

I am always thankful to be working as a medical laboratory technologist, a career I am very passionate about. I remember my journey towards discovering my ideal career, and let me tell you, it was not an easy one. I was in a similar situation as many other students in high school, not fully aware of the full range of career options available to us. And since this crucial decision is made during the second half of high school, many students feel stuck, undecided, and anxious on their career choices prior to entering further studies. Students often choose an educational path during high school without making an informed decision of all the career options available. As a result, there are many new graduates who have trouble finding a job within their field and pursue additional programs in order to acquire more qualifications. I believe a thorough search of the vast number of career options available will help students make an informed decision.

Lab Chronicles: My Experience in the Hematology Laboratory

The clinical hematology laboratory contains two different types of testing: hematological and coagulation testing. On the hematological side of testing, the main test performed is the complete blood count (CBC), which directly measures the number of red blood cells, white blood cells, platelets, and hemoglobin, as well as indirectly measuring other values by calculations (such as the mean corpuscular hemoglobin). These tests are performed using a well-mixed whole blood sample that has been collected in a tube containing ethylene diamine triacetic acid, also known as EDTA. Before hematological results are sent out to the healthcare team, they are reviewed by the medical laboratory technologist (MLT). Any abnormal results that are seen by the MLT (either increased or decreased beyond reference ranges) are made into slides and further microscopic analyses are performed. Some results may even be “critical” in the sense that they are so abnormal that the patient may be at risk of harm if the result is not reported immediately. While reviewing parameters, certain “checks” are also performed as an internal quality control system for the sample. One of these kinds of systems include delta checks, which are a comparison of a patient’s previous results to those most current. While changes in values can occur due to the physiological state of the patient, these internal checks are also great for identifying if a sample was taken from the wrong patient. In addition, H&H checks are performed between the patient’s hemoglobin and hematocrit. The hematocrit should match the hemoglobin within certain values, and if not, an issue with the specimen quality is present, and this should be addressed before results are reported for that patient.

Lab Chronicles: Three Important Lessons I Learned Performing Phlebotomy

One of the main reasons why I chose the medical laboratory profession was for the behind-the-scenes work in the medical field. Nevertheless, I am thankful for those individuals on the front line of the medical profession, directly taking care of patients and their illnesses. Even though this may have the initial reason that drew me to the medical laboratory profession, I have found, throughout my years in university, that I have many other qualities belonging to that of a medical laboratory technologist: I am analytical, process-driven, and a critical thinker. Nonetheless, there has been one aspect of my program that had me a bit worried… Continue reading
