Getting a blood draw

To help assure your safety when getting blood drawn, if any of these apply to you, share appropriate information with the professional who will be collecting your blood before the procedure is performed:

  • Previous problems associated with a blood specimen collection (fainting, pain lasting several days, bruising or swelling at the site).
  • Currently on medication that may cause prolonged bleeding (i.e., chemotherapy, blood thinners such as Coumadin (warfarin), heparin or aspirin therapy).
  • Specific draw sites that have been successful in the past.
  • Previous mastectomy or axillary lymph node dissection.
  • Arteriovenous fistula.

Steps to take to avoid complications

To help avoid complications, such as getting a bruise after a blood draw, apply direct pressure to the site for three to five minutes immediately after the needle is removed. Do not just bend the arm to apply the required pressure as this does not apply enough direct pressure to the actual site.

If a bruise does occur, use general first aid—ice the area and avoid use of the arm. If the area that is bruised causes pain and it does not subside with appropriate first aid measures, seek further medical attention from a health care provider.

You should avoid leaning on or using the arm that the blood was drawn from for exercise or heavy lifting for a few hours to prevent dislodging the fibrin clot that formed to stop the bleeding.
