Often, the simple act of drawing blood can be a source of anxiety for many. Phlebotomy, in its simplest terms, is the practice of drawing blood. While the word itself might sound intimidating, the process, when performed by skilled professionals, is typically quick and painless.
Comfort And Safety Are Top Priorities
Jocelyn Moran, a lab assistant at CCMH, says a simple blood draw is a crucial procedure in achieving a medical diagnosis. She also emphasizes the importance of patient comfort and safety.
“The first thing I do with all of my patients is verify their information. I ask them their first and last name, date of birth, and make sure they’re comfortable before I even get my tools out. This initial step is essential for ensuring patient safety and building trust.”
For those who are anxious, Moran finds that simply talking to patients about everyday things can help calm their nerves. This is especially true for those patients who are unfamiliar with phlebotomy.
Common Procedures
When it comes to the actual blood draw, Moran explained the most common method is venipuncture, which involves drawing blood from a vein inside the arm, typically in the elbow region.
“Nonetheless, depending on the patient’s age or vein condition, other sites, such as the back of the hand or the heel for infants, may be used. The inside of the arm is preferred due to the presence of three main veins, making it easier to locate a suitable site for the blood draw.”
How Many Tubes Are Enough?
One common question patients often have is why multiple tubes of blood are collected during a single draw. Moran clarifies that each tube is used for different types of tests.
“We typically use four main tubes: red, green, blue, and purple,” she explains. “The red tube is for chemistries or drug levels, the green for chemistry tests like electrolytes, and the blue and purple tubes contain clotting agents for coagulation and blood counts.”
One Blood Draw, Many Tests
The variety of tests that can be performed on blood samples is extensive. From checking blood sugar and cholesterol levels to diagnosing anemia and infections, blood tests play a fundamental role in patient care. In fact, it’s estimated that 90% of all diagnoses of disease or illness are made based on blood test results. This underscores the importance of the laboratory, which Moran aptly describes as “the heart of the hospital.”
“Without us, you can’t really do much,” she states, highlighting the lab’s pivotal role in providing necessary information for diagnosis and treatment. This ability to analyze blood has revolutionized medicine, allowing healthcare professionals to identify and address a wide range of medical conditions.
Anxiety About Blood Draws
For those who experience anxiety about blood draws, Moran offers some practical advice.
“Staying well hydrated makes it easier for us to find veins. By staying hydrated, patients can help minimize the discomfort and potential for multiple needle sticks. I also emphasize to patients the importance of having lab orders ready to ensure a smooth and efficient process.”
The Ultimate Goal
The goal of phlebotomy is to provide accurate and timely information that aids in patient care. By understanding the process and the importance of blood tests, patients can feel more at ease during their next blood draw. And by appreciating the work of phlebotomists, we can recognize their vital contribution to healthcare.
