Having your blood taken

In order to perform the necessary tests you will need to have blood drawn from an accessible vein. This is most commonly done on the inside of the elbow but can also be done from the wrist, back of the hand or top of the foot if an accessible vein cannot be located in the inside elbow.

It is likely that you will experience a sharp, localised pain at the site where the needle is injected to draw the blood. In addition you may experience a stinging feeling or either a warm or cold sensation. This is not abnormal and you should not be concerned.

After the blood draw slight pressure will be put on the area followed by application of a plaster or other bandaging material. It is recommended you keep the bandaging in place for at least the next 12 hours.

Side Effects

A blood draw is a relatively simple procedure with a very low risk of side effect. However, they may occur.

Common Side effects –

  • Localised pain, redness, swelling or bruising at the injection site
  • Slight dizziness or feeling of faint during blood draw
  • Bleeding at the injection site

Less common/rare side effects –

  • Infection
  • Dizziness or lightheaded feeling that continues after blood draw
  • Fainting either during or after blood draw
  • Damage to ligaments (only in hand or foot access blood draws)
  • Unabated bleeding at injection site

*IMPORTANT* - Although most side effects are minor and will resolve on their own it is critical that if any of the less common or more serious side effects occur and symptoms do not abate within the first 24hours after the blood draw you MUST SEEK IMMEDIATE MEDICAL ATTENTION.

Failure to seek immediate medical attention for a serious side effect can lead to more severe and potentially irreversible damage including widespread infection requiring surgical intervention, kidney damage, organ failure, head trauma, coma and even death.

Please do not drive if you are experiencing any serious side effects such as fainting and dizziness.
