What degrees should a needle be inserted during drawing blood?

When drawing blood, the needle is typically inserted at a 15 to 30-degree angle for veins located close to the surface, such as in the antecubital fossa (the crease of the elbow). For deeper veins, a slightly higher angle may be appropriate, but generally, a 15 to 30-degree angle is ideal for most venipunctures. Proper technique helps ensure a successful draw while minimizing discomfort for the patient.
