Why is Phlebotomy Important in Medicine?

Trained medical technicians who specialize in drawing blood from patients, Phlebotomists are a vital part of modern medicine, drawing vital uncontaminated blood for the blood tests which remain the bedrock of diagnostic science.


If you’re considering becoming a phlebotomist, here are some ways in which phlebotomy is crucial in the medical profession.

Diagnosis and Prediction

The results of blood tests are used in 80% of diagnosis in modern medicine. A huge range of medical issues, such as blood disorders, bacterial infections, viruses, even some types of cancer can be detected through blood tests. 


These hugely important tests are useless, however, if the blood is contaminated during the draw, which is why a properly trained and effective phlebotomist is such an important part of the process.

Patient Care

Needle phobia is a fear of medical procedures that involve needles or injections. It is very

common, affecting at least one in 10 people, and is nothing to be ashamed of. Fortunately,

simple exercises and practice can help to overcome it.

Many patients with needle phobia may have had a lot of blood tests or procedures as a child. A

fear of needles and injections often, but not always, results from bad memories of needles

earlier in life. 


A well trained and effectively phlebotomist is able to put their patient at ease before drawing blood, demonstrating the method, answering the patient’s questions and generally making sure they are as happy as possible with the whole procedure before even producing a needle.

Uncommunicative Patients

Unfortunately, not all patients are able to accurately communicate, or trouble remembering their symptoms. As the US medical system deals with an increasingly aged population, the number of elderly patients who suffer from memory loss or dementia is rising.

Phlebotomy allows healthcare providers to diagnose patients who are in distress but cannot communicate why. This applies as much to patients with mental and physical disabilities that prevent accurate communication with their doctors as it does to geriatric patients.

Neonatal Medicine

Blood tests represent a vital window into the health of both mother and baby during pregnancy. A regular blood test can help to identify potential problems with the mother, such as anemia and gestational diabetes. They can also be used to check a newborn for any potential issues during the first few hours outside the womb.
