Blood Sample

If you are a medical assistant, nurse, or any other medical professional, you would have several recurring tasks, and one of them is drawing of patient’s blood sample for different purposes such as private blood tests. This procedure is a simple and straightforward one, but to ensure your safety and that of the patients, you need to know the right steps involved.

Right Steps To Take Blood Sample

Here are the right steps to take for the proper collection of a patient’s blood sample.

  • Step 1

Before your patient arrives, you should have prepared your work area. The collection of blood samples is supposed to be in a sterile and clean environment, and you also need to have the right equipment at hand. Get your venepuncture device, the blood sample collection tubes, gloves, disinfectants, tourniquets, labels, and lab form ready.

  • Step 2

When your patient arrives, introduce yourself and confirm the identity of the patient. Ask the patient if he/she has allergies and if they usually have an issue during blood collection. Try to comfort the patient and assure him/her that the procedure is usually painless.

  • Step 3

Before you start the blood drawing process, wash your hands thoroughly, then wear your clean pair of hand gloves. Request for the patient’s arm and examine it for a suitable vein for the blood draw. A vein is usually easy to find even without using a tourniquet. If you do not see a visible vein, ask the patient to make a fist and hold still.

  • Step 4

When you locate a vein, place your tourniquet about 3 – 4 inches above the spot you intend to insert the needle. Use an alcohol swab to disinfect the site you want to insert the needle then let it dry. Try not to touch the area until you complete the collection process.

  • Step 5

While you still have the tourniquet on the patient’s arm, with your thumb beneath the site you intend to inject, insert the sterile needle into patient’s vein, placing the needle at an angle of 15 – 30 degrees.

  • Step 6

Draw the blood, and collect it into the right blood collection tubes. Blood collection tubes have different colors, and each sample container is suitable for a specific test.

  • Step 7

After collecting the right amount of blood, remove the tourniquet from the patient’s arm, then gently take out the needle. Using gauze or a ball of cotton, apply a little pressure on the punctured site and ask the patient to continue applying the pressure, while you secure the area with sterile tape.

  • Step 8

Dispose of the collection device and needles correctly in a biohazard bin. Label the sample correctly with the patient’s full name, time of sample collection, date of collection, and the patient’s date of birth.

  • Step 9

After the collection, labeling, and disposal of the used needles and equipment, rewash your hands and clean the area, then check your patient to know how he/she is feeling. If the patient is feeling okay, he/she is free to leave.

  • Step 10

Prepare the samples collected for transportation in a labeled leak-proof bag, then clean and sterilize your work area for the next patient.
