Having Your Blood Collected

Although blood collection is a routine procedure requested by your physician, there are some potential risks:

·         Bruising at the puncture site

·         Bleeding from the puncture site

·         Minor discomfort

·         Tingling of the arm

·         Painful swelling



Follow these steps to ensure risks are limited:

·         Apply immediate pressure on puncture site for a minimum of 5 minutes.

·         Leave the bandage on for at least 15 minutes.

·         Carry items with the opposite arm and avoid lifting heavy objects for at least 2 hours after blood collection.

·         Avoid activities that may put stress on the puncture site.

·         Inform the staff before collection if you have had a mastectomy.

If you experience symptoms related to the risks of blood collection, please contact your family physician.


Please inform laboratory staff if you are concerned that you may faint.
