When we get sick and go to the doctor, they say, "Come and get a blood test," right? Then we go to a medical laboratory, that is, a lab. There, there is someone who uses a needle to take a little blood from our arm. Some people feel a little scared and nervous at this time. But this is someone who has received special training for this job and knows it very well. Today we are talking about that medical professional, that is, a Phlebotomist.
Simply put, who is this Phlebotomist?
A phlebotomist is a medical professional who is specially trained to take blood samples. They take blood from adults and children alike. The blood samples obtained in this way are tested in medical laboratories and used to diagnose diseases or monitor certain medical conditions. Phlebotomists are also the ones who collect blood when someone donates blood.
Although other medical professionals, such as nurses, can also draw blood, this is the main and most specialized job of a phlebotomist. That's why they are very skilled at this job.
The word "Phlebotomy" comes from the Greek language. "Phleb" means "vein" and "tomia" means "cutting." So that pretty much sums up the nature of this profession, right?
Main methods of obtaining blood
A phlebotomist draws blood in three main ways.
| Method | Description |
|---|---|
| Venipuncture | This is the usual method we all know: inserting a needle into a vein in the arm, usually near the elbow, and drawing blood. |
| Finger pricks | A small prick of the fingertip to obtain a drop of blood. This method is used for things like blood sugar tests for diabetes. |
| Heel pricks | This is done on newborn babies. Blood samples are taken from their heel area. |
What are the main duties of a Phlebotomist?
A phlebotomist has many broader responsibilities than just drawing blood. All of this is done to ensure your safety and the accuracy of the test.
| Duty | What does that mean? |
|---|---|
| Preparing patients | Talking and calming someone who is afraid of needles and nervous. They know how to work very well, especially with young children. |
| Verifying personal identity | Before taking blood, they ask for your name and age to make sure you are a genuine person. This is very important, because if the blood sample is mixed up, it will be a big problem. |
| Sanitization of equipment | We ensure that all equipment used, especially needles, is sterilized and clean. This will prevent you from getting infections. |
| Proper labeling of blood samples | After your blood is drawn, your name and number are accurately recorded on the tube (vial). |
| Help with side effects | Some people may feel faint after having blood drawn. They are also trained to help them if that happens. |
| Sample maintenance and shipping | It is also their responsibility to properly store and monitor the collected blood samples until they are sent to the laboratory. |
What really happens when your blood is taken?
Let's take a step-by-step look at how the blood donation process works when you go to a lab. Knowing this will greatly reduce your fear.
1. Introduction and Verification: First, the Phlebotomist will smile at you and tell you who he/she is. Then, he/she will ask for your name and details to verify your identity.
2. Preparation: Next, he will put gloves on your hands. Then he will put a tourniquet around your upper arm. This will help control the blood flow and make it easier to find the vein.
3. Identifying the vein: Next, the site of the blood draw is thoroughly cleaned with an alcohol swab. Then, he or she presses the vein with his or her finger to select the best vein to draw blood from.
4. Inserting the needle: This is where the needle is inserted into the vein. At this point, you will feel a slight sting, like being bitten by an ant , but it will only last for a few seconds. Taking a deep breath will make it easier for you.
5. Blood collection: After the needle is inserted into the vein, a small tube (vial) connected to it is filled with blood. Depending on the tests your doctor has ordered, one or more tubes may be filled.
6. Finishing: After the required amount of blood has been collected, the tourniquet is loosened and the needle is carefully removed.
7. Stop the bleeding: They will ask you to place a piece of cotton over the puncture site and hold it there for a while. Then they will apply a small plaster to the area. Now you're done!
Remember, this entire process only takes a few minutes. If you're feeling nervous, tell the phlebotomist. They will help you.
Where does a phlebotomist work?
A phlebotomist is an indispensable person in many areas of the healthcare industry. They typically work in places like:
- Clinical laboratories
- Government and private hospitals
- Community health centers
- Doctor's offices
- Blood donation centers and blood drives
- Assisted living facilities and nursing homes
What do you need to do to become a Phlebotomist?
Since this is also a responsible profession, it requires special training and certification. In Sri Lanka, this usually requires a diploma or certificate course from a recognized institution.
These are the general steps to becoming a Phlebotomist:
1. Educational Qualification: Passing G.C.E. (Ordinary Level) or (Advanced Level) is a basic qualification.
2. Training Course: Take a Phlebotomy course at a recognized institution. These courses can usually be completed in less than a year. They provide both theoretical knowledge and hands-on training.
3. Practical Training: You will need to undergo practical training under an experienced Phlebotomist in a hospital or laboratory.
4. Obtaining Certificates: After successfully completing the course and training, you will receive the relevant certificate.
In foreign countries, there are different levels of certification for this. For example:
- Limited Phlebotomy Technician (LPT): Certified only to draw blood from the surface of the skin (such as the fingertips).
- Certified Phlebotomy Technician I (CPT I): Certified to draw blood from the skin and veins.
- Certified Phlebotomy Technician II (CPT II): Certified to take blood from the skin, veins, and even arteries (arterial puncture).
This shows how specialized knowledge this profession requires.
