What exactly is Medical Laboratory Technology

What exactly is Medical Laboratory Technology? It’s a branch of Pathology, the medical specialty that studies disease. There are five major disciplines, Clinical Chemistry, Hematology, Medical Microbiology, Histology and Transfusion Medicine. So how do these relate to you, the patient?

Disclaimer: The following is only an example and is entirely fictional. Information given cannot be used to take the place of a licensed medical doctor’s care.

Why was that disclaimer written? As soon as the term ‘sore throat’ is used, the reader will instantly swallow to make sure that their throat is fine. Everyone has had this complaint at least once, and it is common reason to see your doctor.
What does the doctor do? Looks down the patient’s throat, and usually sticks a swab down there to give the patient’s gagging reflex a workout. Where does the swab go? To the lab, to the Microbiology department where the lab tech will analyze it to determine if:

1) There is an infection present
2) What is causing it

So after the swab is analyzed the lab it is determined that the sore throat is not caused by an infection. What’s next? The physician notices a lump in the throat and decides that a biopsy or tissue sample of it needs to be taken. After surgery, the specimen is sent to the lab to the Histology department.
Histology is the study of tissues. The lab techs in this department process the tissue specimen and cut into slices thinner than human hair, put them on glass slides, and then stain them for the pathologist to examine microscopically. After looking at the slides, the diagnosis comes back as cancer of the throat.

Once again I have to emphasize this is only a fictionalized example. The care of a sore throat is best done by a licensed healthcare professional.

Of course the best treatment is surgery to remove the tumor, and since there is a chance of bleeding, the surgeon will need to have some units of blood on hand. The lab techs in Transfusion Medicine will be responsible to make sure there are safe blood products available for this scenario.
So after surgery, the tumor has been removed and the next course of treatment is chemotherapy. Hematology, the study of blood cells, will be used to make sure that the body’s immune system can tolerate this treatment, while Clinical Chemistry will ensure your organs will be able to handle it as well.
Once again, I cannot stress it enough, if you have a sore throat, please see your doctor about it. Please do not tell him that the Labvocate told you it is cancer.
So to review, the five disciplines of Medical Laboratory Technology are:
1) Hematology
2) Clinical Chemistry
3) Transfusion Medicine
4) Microbiology
5) Histology

I have worked in all of them, and each one has its advantages and disadvantages. But no matter what department, I always remember what was drilled into our heads by our instructors:
“Treat each specimen as if it’s from someone important to you.”
Thank you for taking the time to read my posting. I look forward to your thoughts and comments..
