Phlebotomy is the process of piercing the flesh with a needle in order to enter a vein and extract blood from the body. This is also known as venipuncture. The terminology comes from the Greek word “phlebo” meaning vein, and “tom” meaning cut. Most often the blood is used for diagnostic (testing) purposes and at times this process can be done to replace blood loss (transfusion). Regular phlebotomy is undergone by patients who have too much iron in their blood or are producing too many red blood cells. Removal of blood decreases the excess level of iron in the red blood cells.

You may have faced a situation in which you needed to donate blood, or perhaps took part in a blood group test. You may have realized that you did not experience any discomfort or pain when the needle was inserted into the vein to draw blood, or even while it was being removed. The person who administered this procedure to you was, in fact, a Phlebotomist trained in phlebotomy.

A Phlebotomist is a person who has the ability to find a vein beneath the skin, inject the needle and extract blood with ease, even within seconds. They also monitor blood pressure and pulse in situations like blood transfusions or blood donation at the blood banks. Phlebotomists are integral and vital members of the healthcare team, as the blood they collect is used for diagnostic testing which helps the physicians to make informed decisions. They also act as life guardians with their services at the blood banks encouraging blood donation campaigns.

Phlebotomy is safe when done by a well-trained professional. The phlebotomist bears in mind factors such as the bruising of the skin where it is punctured, inflammation of veins, and possible chances of infection at the punctured sites while performing venipunctures or skin punctures. The skin puncture is done using finger sticks wherein small blood samples need to be collected. In the case of infants, a heel stick is used. At times it may be required to draw blood from arteries or capillary beds; a specimen which is easily done by these trained professionals. phlebotomists may at times be required to ascertain stool and urine sample collection and testing. Phlebotomists do not administer drugs or any intravenous fluids that require injections.

In the United States the phlebotomists are unlicensed medical care professionals, except in the state of California. In California, licensing is mandatory for phlebotomists in order to work with any clinical laboratory, hospital, research institution, public health clinics or blood bank.

Those who have undergone vocational training, graduated in phlebotomy or spent approximately two years in the field should enroll in a certification course. This will help with proficiency in human anatomy, technical skills, interpersonal skills, lab safety rules, as well as compliance with CDC & OSHA requirements. In addition, many other pre-requisites such as blood collection techniques, specimen record management and data entry maintenance for the purposes of report generation, will be covered.

The phlebotomist is an important member of the medical team and this fact is evident in compensation statistics. The median salary drawn in the U.S. is $29,040. Coupled with the pay, is the flexible work hours that make this profession even more exciting.



Did you know that many STD’s aren’t routinely tested for at your doctor or office visit? Most test for
STD’s are done at your request or if you’re pregnant. A pregnant woman with an STD such as Herpes or HIV is at risk of transferring the virus to her unborn baby resulting in severe illness or death. Because of the rising epidemic of HIV infected individuals and herpes cases today, it is very important to get tested. This is especially so because Herpes and HIV are incurable; with HIV being potentially fatal. People fear getting tested but once you know your status it can empower you to take better care of yourself and be more responsible.

Let’s start with testing done for Herpes. If you have sores on your genitals, a sample can be taken and cultured. The virus multiplies and can be seen under a microscope. Another test involves a solution which contains antibodies that is added to the sample. The virus multiplies and glows when viewed under a special microscope. The only drawback with this type of testing is that the virus is detected only in it’s active form. These test can also tell you what type of herpes you have and how you were infected. HSV 1 can be transmitted to the genitals through oral sex and HSV 2 can be transmitted through intercourse or anal sex.

As stated above, the culture detects the herpes virus in it’s active form. False negative results are
possible if the sores have begun healing or if this isn’t your first outbreak. Blood test for herpes are done
when there are no symptoms and are more accurate. However, if you are newly infected it may not show up for several weeks since it takes time for antibodies to the virus to show up in the blood. That is why if you suspect you may be infected you should have a repeat test several weeks after the first one.

The HIV test most commonly used in the US is the EIA or enzyme immunoassay formerly known as (Elisa). This test on blood samples looks for antibodies(http:en.wikipedia.org/wiki/Antibodies) to the HIV virus. A positive EIA must be confirmed with a Western Blot(http:en.wikipedia.org/wiki/Western_blot)on the same sample. HIV test using oral fluids are obtained from the mouth with a special device. Saliva isn’t used for testing but oral fluids found in the mouth. The test is similar to the EIA test done on blood. If the test is positive then a Western Blot is done on the same oral sample to confirm the results.

There are rapid HIV screening test but if reactive must also be confirmed by the Western Blot. Home testing kits are popular since being licensed in 1997, but only one has been approved by the FDA. The Home Access HIV 1 Test System is a home collection kit. The kit has instructions on how to obtain a sample, mailing it and how to obtain your results. There are supportive services available throughout this process.
