Most routine laboratory tests require a blood sample. Common as it is, this brief procedure is the test people tend to have the most worries about.

There are two main problems really: 1) the physical one, enduring the needle and 2) the emotional one, seeing your blood being removed.

For most people, having your blood taken is not a problem, just a minor inconvenience. Others feel anxious and need some strategies to help them cope. For a much smaller number of individuals, the physical condition of their veins makes the procedure harder, for example their veins are sore from intravenous (IV) therapy, scarred from frequent venipunctures, or just hard to find and use.
