Blood test safety information

Blood test safety information


To prevent fainting during a blood test:

Please inform staff member if you feel you may faint during the test and you will be able to lie down

If you do faint, this is usually short lasting and will cause no permanent damage

The event will be documented as an incident

To prevent bruising and bleeding after a blood test:

Avoid excessive movement such as: digging, jogging, and carrying heavy objects/children etc, for 1 hour as the arm involved may become bruised

Pressure is required to minimize bruising and prevent bleeding (clot forms)

Remove dressing in approximately 15 minutes otherwise tape may cause irritation

If you experience pain either during or after a blood test:

This is usually transient, is often unavoidable and recovery is usually rapid.

If severe, please inform staff member immediately

The cause of the pain may be one of two things: either the vein has been punctured on both sides causing blood to leak into the surrounding tissues or a nerve has been injured

Ice may be applied to the site and any adverse effect of the blood test will be documented as an incident

If you are concerned, please contact the collection centre where your specimen was collected. Or for further information, please call 09 438 4243.
