None of them are a cause for concern, or a reflection on your injection technique. If you see blood at the injection site after the needle is removed, you likely nicked a small blood vessel at or below the skin surface, and blood is following the needle track out to the surface.
What size needle do they use to draw blood? While the size can vary, most needle sizes are 21 to 23 gauge. If a person uses the smaller-sized needles (such as 25 to 27 gauge), blood is more likely to get destroyed (hemolyze) or clot due to the smaller-sized needle.
What size needle is used for Covid vaccine?

Is a butterfly needle less painful?

As the “painless needle” requires delicate processing, even small chips and cracks—let alone uneven surfaces—cannot be tolerated.
Do 23G needles hurt? The mean pain score of the 23G needle group was 3.5 (SD=2.7) and for the 25G needle group 3.4 (SD=2.7) (table 2 and figure 4). The mean difference between the pain scores was 0.1 (95% CI −0.9 to 1.1, p=0.83).
What is the diameter of a needle?
The needle gauge (G) refers to the width (diameter) of the needle. The higher the gauge number, the narrower the needle. For example, a 25 G needle is approximately 0.5 mm in diameter and is narrower than a 23 G needle, which has a diameter of 0.6 mm.
What size needle do you use for flu vaccine?
