If bruise apears after blood test what does it mean?

Answer 1

Bruising after a blood test is quite common. Sometimes the site where the blood was taken is not held tightly enough to allow for it to completely clot, allowing blood to seep from the vein and collect under the skin forming a bruise. The bruise will typically go away within a week.

Answer 2

A bruise or hematoma after a blood test usually indicates that a small blood vessel was injured during the procedure, leading to blood leaking into the surrounding tissues. This is a common and generally harmless occurrence that typically resolves on its own within a few days.
