What is the correct angle for inserting a needle during venipuncture?

The correct angle for inserting a needle during venipuncture is between 15 to 30 degrees. This angle is recommended to ensure that the needle enters the vein properly, minimizing the risk of puncturing through the other side of the vein while also allowing for efficient blood flow into the collection device.

Inserting the needle at this angle strikes a balance; it is steep enough to penetrate the vein wall effectively but not so steep that it risks causing damage or discomfort. This technique is particularly important in obtaining a blood sample successfully and safely, as it helps the phlebotomist locate and enter the vein while maintaining control during the procedure.

Different angles may be appropriate for various situations, but 15 to 30 degrees is generally taught as standard practice for most adult patients when accessing superficial veins.
