A dermal puncture is preferred over a venipuncture in young children, especially infants, when obtaining small blood samples is necessary, such as for blood glucose monitoring or when only a few drops of blood are required. It minimizes discomfort and reduces the risk of complications associated with larger needles and venous access. Additionally, dermal punctures are often more convenient and can be performed quickly at the point of care.
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.
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.

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.

Povidone-iodine may elevate test results for bilirubin, uric acid, phosphorus, and potassium, and therefore is not recommended for use with dermal puncture
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.

Your skin is the dermal.
The dermal tissue structures responsible for fingerprints are dermal papillae. They are tiny extensions of the dermis into the epidermis.
