Finger - Usually the third or fourth finger is preferred in adults and children. The thumb has a pulse and is likely to bleed excessively. The index finger can be calloused or sensitive and the little finger does not have enough tissue to prevent hitting the bone with the lancet.
The best finger to get blood from is your ring finger. When performing a finger-prick test, use the side of your ring finger. It is where circulation is at its peak, and you are more likely to collect a complete sample from this one finger.
By the way: make sure to avoid pricking thumbs and index fingers as they are most commonly used to touch and feel.
Potential Cause: Poor circulation. Solution: Let your hand hang down, and flap or shake your hands and arms to get blood flowing. Potential Cause: Lancing depth is too shallow. Solution: Many lancing devices have adjustable settings to control how deep the lancet will puncture.
Note: The best locations for finger sticks are the 3rd and 4th fingers of the non-dominant hand. Do not use the tip of the finger or the center of the finger. Avoid the side of the finger where there is less soft tissue, where vessels and nerves are located, and where the bone is closer to the surface.
The left-hand little finger, aka pinky, is the smallest and weakest of our fingers. It is shorter than other fingers.
Conclusions: The middle finger was the most important contributor to grip strength. The next most important was the combination of the ring and little fingers.
The bleeding will often stop when pressure is put on the wound. Dr. Brown says in most cases holding direct pressure with clean gauze or a cloth for four to five minutes should stop the bleeding.
If you have been to a clinic or lab before and had the phlebotomist stick you more than once for a blood draw, you may have been told that you are a "difficult stick." This can happen to people for quite a few different reasons, including small or deep veins, rolling veins, dehydration, collapsing veins, constricted ...

It is located between the first and third digits, between the thumb and the middle finger. It is usually the most dextrous and sensitive finger of the hand, though not the longest.
Littler fingertips are likely more sensitive because of the distribution of sensory receptors—the less surface area to spread out across, the closer together the receptors are.
Wipe away the first drop of blood because it may be contaminated with tissue fluid or debris (sloughing skin). Avoid squeezing the finger or heel too tightly because this dilutes the specimen with tissue fluid (plasma) and increases the probability of haemolysis (60).
Don't forget the thumb.
It can be less sensitive because it's usually more callused.
Change up the location of your finger prick. If you put your hands together, palms touching, you will be able to see the areas of your fingers with fewer nerve-endings. Pricking the sides of your fingers can be less painful because there are fewer nerves there.
Wear clothing with sleeves that can be raised over the elbow. Keep your arms warm during cold weather to prevent your veins from constricting. Let the phlebotomist know if you have a preferred arm or vein that has been successful in the past. We use the smallest needle possible for each draw.
If the needle doesn't penetrate the wall of the vein, the blood flow will be very slow. In this case, the phlebotomist should gently push the needle into the vein. If the vein is not well anchored during needle insertion, the needle can slip to the side of the vein instead of into the vein.
If blood spurts from the wound, or it does not stop bleeding after 10 to 15 minutes of pressure, seek medical help. You may need stitches. After bleeding stops, rinse the cut thoroughly with cool water.
a wound more than three-quarters of an inch in length. a wound more than a quarter of an inch deep. an injury that exposes the bone. bleeding that does not stop, even after compressing and elevating the injured finger.
The fourth finger of the left hand, believed to possess a vein that runs securely to the heart, has traditionally been ringed. This Vein of Love, or more amorously called the Vena Amoris, 1 originated in ancient Egypt, where it was first described by Macrobius in 395–423 AD.
It is commonly believed that the index finger is the most “dominant” finger: “It serves to exemplify the pre- cise movements of the human hand” (Crow, 1974). The index finger is also commonly the finger of choice for reconstruction of a usable thumb (Littler, 1953).
