Phlebotomy Technician


A phlebotomist is a medical professional who is responsible for performing venipuncture on patients in a medical environment such as a health screenings, hospital, lab, or doctor's office. A phlebotomist assists other medical workers by focusing entirely on the collection of blood, tissue, and fluid samples. Many times a phlebotomist works with organizations that only perform phlebotomy for their patients.

The duties of a phlebotomist can be divided into five general functions:

  • Prepares and maintains necessary equipment and supplies.
  • Performs venipuncture, arterial puncture, capillary puncture, and other fluid collection. procedures on patients, and ensures specimens are appropriately labeled and identified.
  • Assists the patient before, during, and after collection of the specimen.
  • Prepare the blood to be screened at a laboratory by labeling and centrifuging the specimen.
  • Must maintain patient confidentiality, keep necessary records, and document results.

Venipuncture is a phlebotomist's main duty. Venipuncture refers to the act of withdrawing or extracting a blood sample from a patient, usually using a needle. This needle is inserted into a vein, upon which blood is extracted from the vein. This blood may be used to perform tests, or may be a blood donation from the patient.

Electrocardiography Technician


Electrocardiogram (ECG) technicians use special equipment and medical techniques to record the electrical impulses transmitted by a patient's heart. Data acquired by electrocardiogram technicians assists physicians and cardiologists in diagnosing medical conditions in patients. Training for this career typically is done by the ECG technician's employer.

Job Description

Electrocardiogram technicians generally are employed in hospitals, laboratories or cardiologists' offices. They typically work 40 hours a week, although occasional weekend work might be required as well. ECG technicians employed with laboratories tend to put in longer hours. Additionally, they may be required to be on call and come in at odd hours.

ECG technicians should expect to perform heavy lifting on a regular basis as they move patients and equipment. They also should be prepared to work with patients who are suffering or have serious heart conditions.

Job Duties

An electrocardiogram technician performs an ECG by attaching electrodes to a patient and then pulling switches on an ECG machine to trace electrical impulses transmitted by the heart. A doctor then inspects these readings to analyze the patient's heart condition.

ECG technicians also might perform stress tests. This involves hooking up a patient to an ECG monitor for a baseline reading and then monitoring the patient's heart while he or she exercises on a treadmill. During the monitoring period, the treadmill speeds up and slows down to produce ECG readings at multiple levels of physical exertion.

With advanced training, ECG technicians can administer Holter monitoring tests. With this procedure, the technician attaches an ECG monitor to a patient, then allows the patient to go about his or her normal routine for a 24-hour period. Next, the electrocardiogram technician removes the monitor and takes it to a scanner, from which he or she can print out the data recorded by the machine.

Unlike most cardiovascular technicians, electrocardiogram technicians typically receive their education through job training from an experienced cardiologist or ECG supervisor. Training generally last 4-6 weeks, although learning to conduct Holter monitoring procedures takes longer. Alternatively, aspiring ECG technicians might complete a cardiology certificate program offered through a community college or technical school.
