Puncture to the finger tips
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.
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 site of the dermal ridges that produce epidermal ridges on the fingers is called the dermal papillae. These papillae create the unique patterns found on the fingertips, known as fingerprints.
The protective outer layer of the plant. Everything needs skin, or at least some sort of a covering, for plants, it's a system of dermal tissue. Which covers the outside of a plant and it protects the plant in a variety of ways. Dermal tissue called epidermis is made up of live parenchyma cells in the non-woody parts of plants. Epidermal cells can secrete a wax-coated substance on leaves and stems, which becomes the cuticle. Dermal tissue that is made up of dead parenchyma cells is what makes up the outer bark in woody plants. The dermal tissue system is one of three tissue systems, the other two being vascular and ground tissue systems.
Dermal tears can appear as red, painful lacerations on the surface of the skin. They may also show signs of bruising and swelling around the affected area. In severe cases, the skin may split open, exposing the underlying tissues.

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 to obtain capillary blood specimens, the recommended fingers are typically the middle or ring finger of the non-dominant hand. These fingers have adequate blood supply and are less likely to be calloused compared to the index finger. The puncture should be made on the side of the fingertip to minimize discomfort and maximize blood flow. In infants, the heel is often used for this procedure.
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.
The first drop of blood should be wiped away during a dermal puncture to remove any potential contaminants from the skin surface, such as tissue fluid, dirt, or debris. This helps ensure that the sample collected is representative of the blood and not influenced by external factors. Additionally, wiping away the first drop can help minimize the risk of hemolysis or skewed results caused by interstitial fluid.
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.
