Other than potential bruising at the puncture site, and/or dizziness, there are no complications associated with this test
For dermal puncture, the depth is typically 2.4 millimeters (mm) or less, which is around 2-3 mm in adults and 0.85-1.0 mm in infants. It is important to control the depth to avoid going too deep and causing pain or complications.
The complications associated with drawing blood are minimal, but may include bleeding from the puncture site, feeling faint or lightheaded after the blood is drawn, or blood accumulating under the puncture site (hematoma).
Dermal puncture refers to a technique used to obtain capillary blood samples by pricking the skin using a lancet or needle. It is commonly done on the finger, heel, or other suitable site for blood collection in medical settings such as hospitals, clinics, or laboratories.

capillary blood collection
One example of a test taken from a dermal puncture is a blood glucose test. Dermal punctures are preferred for this test as they are less invasive, cause minimal discomfort, and can be easily performed on individuals with difficult-to-access veins such as infants or elderly patients.
Povidone iodine may falsely elevate potassium levels if not adequately cleansed from the skin before a dermal puncture. It can also interfere with testing for iodine levels due to its iodine content.
Risks for this test are minimal, but may include slight bleeding from the blood-drawing site, fainting or feeling lightheaded after venipuncture, or hematoma (blood accumulating under the puncture site).

If you are trying to compare numbers from one draw to the next, it would be best to use the same procedure each time. Dermal puncture and venipuncture can give different answers depending on technique.
Complications of a bruise or swelling around the puncture site, which can be treated with moist warm compresses. People with coagulation problems may bleed for a longer period than normal.
