Capillary Blood Sampling
Currently no guidelines available.
Step by step
Prepare the required materials: a lancet, capillary tubes that are heparinized or cuvette for machine, alcohol gauze swabs or cotton swabs, gauze swab or band-aid, non-sterile gloves and hand disinfecting alcohol.
Selecting the lancet
Because the skin is compressed during the puncture, a lancet slightly shorter than the depth needed is used. This is based on the patient’s size (neonate versus adult) and the site of the puncture (finger versus heel). Thicker and longer lancets are generally more painful and run the risk of injuring the underlying bone.
