Bruising Information

Although our skilled phlebotomists take every precaution to draw blood safely, bruising can sometimes occur after a blood test. Bruising is more common in:

• Older individuals
• People taking medications like blood thinners or steroids
• Cases where firm pressure isn't applied to the venepuncture site immediately after the procedure
• Situations where the arm is used for strenuous activities, such as heavy lifting, soon after the test

To minimise the risk of bruising after a blood test, apply firm pressure to the puncture site with clean cotton wool or gauze for at least five minutes. This simple step can significantly reduce the chance of bruising.

Whilst unsightly, bruising is harmless and the trapped blood will be reabsorbed by the body. This happens gradually over 10-14 days, but occasionally takes longer.

To help the bruise heal, we recommend following the R.I.C.E guidance:

Rest - allow time for the bruise to heal. Protect the bruise by avoiding heavy lifting, e.g. at the gym or carrying heavy shopping, and only light, gentle movement is recommended

Ice - do not place directly on the skin but under a cloth

Compression - pressing on the point where the needle was inserted when a bruise has developed

Elevation - if possible, raise your arm above the level of your heart when at rest

If you are experiencing any of the following you should seek further medical help:

• Severe or worsening pain

• Numbness or pins and needles to your arm, hand or finger

• Swelling that is large or increasing in size

• Painful redness/inflammation

• Coldness or paleness of your lower arm or hand of the affected arm
