You have just had some blood removed. This procedure is called phlebotomy (say "fleh-BAW-tuh-mee").
People have their blood taken (drawn) for several reasons. You may have just donated blood so that it can be used to help someone else. Or you may have had blood removed to treat a medical condition, such as hemochromatosis or polycythemia. These take more blood than the sample that is needed for simple lab tests. For donation, about a pint of blood is drawn. If it's drawn for treatment, then more or less than a pint may be taken.
The puncture wound caused by the poke from the needle for giving blood usually heals without trouble. Most people feel fine after they give blood. But there are some simple things you can do to take care of yourself before you go home.

Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
