Why do I have a bruise after getting blood drawn ?

Occasionally, bruising may develop at the venepuncture site. It is usually harmless and recovers within a few days.

This can be because there was a lack of pressure at the site of the jab. Bruising can be minimised by applying pressure over the puncture area, until bleeding stops (never pat).

There are some other contributing factors to consider:

  • Difficulty taking the sample
  • Taking anticoagulant drugs
  • Folding the arm, without pressing on the cotton pad
  • A tight, rolled-up sleeve which acts as a tourniquet
  • Intense physical exercise using the arm concerned within an hour of the sample

The haematoma recovers within a few days. Applying cold compresses to the area or gently massaging the area with a cream, such as arnica can also help to relieve any pain or discomfort.
