Clinical Chemistry and You

Have you ever wondered why diabetics need insulin? Why they don’t produce insulin? Did it ever occurred to you that MedTechs have to perform quality control tests  on their instruments in the lab to ensure reliable results? Did it ever also occurred to you that there are precise sites in your body to collect blood and not just anywhere in it?




The human body is a complex body because it consists of a lot of chemical processes that enables it to function. These chemical processes are so important that one single abnormality can cause a disease. Once the disease is established, that’s where Clinical Chemistry comes in. Clinical Chemistry or CC, measures the amount of enzymes or hormones produced by the organs affected which can give clues leading to the right diagnosis. The usual specimen that subject to CC are usually blood and urine but that doesn’t mean the tests performed on blood will be the same on urine, no. Many different types of tests exist to test for almost any type of chemical component in blood or urine. Components may include blood glucose, electrolytes, enzymes, hormones, lipids or fats, other metabolic substances, and proteins. By measuring this said components in either blood or urine, it can help the MedTech find out what disease is affecting the patient.

Knowledge in CC can also be used in detecting drug abuse and other chemicals; which is useful in dealing with drug addicts. But one of the important lessons that you can learn in CC is how to perform venipuncture; the procedure of collecting blood, it’s not as easy as it sounds. Venipuncture is an exact science because you have to be patient, confident and have nerves of steel to accomplish it. Many people don’t know how frustrating it is  when the right vein is too subtle to palpate because you can’t just stick the syringe anywhere in the patient’s body and extract blood. Finding the right vein means finding the ideal blood to be examined.

In finding pathological diseases, CC can give the right answer provided the instruments used are accurate and precise.
