Why are capillary punctures performed?

Capillary blood sampling is becoming a common way to minimize the amount of blood drawn from a patient. The 10 or 20 microliters can be used to look for anemia, check blood sugar or even to evaluate thyroid function. The procedure is easier and less painful than traditional venipuncture which draws blood from a vein.

Why do you wipe off the first drop of blood in capillary puncture?

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).

What are the disadvantages of skin puncture?

Disadvantages of Capillary Blood Collection Problems with bleeding and infection can occur with either method. Patients may feel faint after any type of blood drawing. Overuse of the same area for collection can cause scarring. Calcified nodules can develop at the site of collection, especially in infants.

What is the difference between venipuncture and dermal puncture?

In some situations, the phlebotomist will make the decision if a blood specimen will be obtained by dermal puncture or venipuncture. A dermal puncture requires less precision, therefore it is less critical for the patient to be still or immobilized.

How do you get venous blood?

The blood is obtained by direct puncture to a vein, most often located in the antecubital area of the arm or the back (top) of the hand. At times, venous blood may be obtained using a vascular access device (VAD) such as a central venous pressure line or Hickmann Catheter or an IV start.

How do you collect blood from your finger?

What is the order of draw?

Order of draw is the tube sequence a certified phlebotomist needs to follow while collecting blood. Each tube is differentiated by the tube additive and color.

Perform the stick off to side of the center of the finger. NEVER use the tip or center of the finger. Avoid fingers that are cold, cyanotic, swollen, scarred or covered with a rash. Massage to warm the finger and increase blood flow by gently squeezing from hand to fingertip 5-6 times.

What is the most important thing to remember when doing a capillary puncture?

The most important thing to remember when doing a capillary puncture is that excessively milking the finger during a skin puncture can result in full tubes for testing, as well as hemolysis and contamination of the specimen with tissue cells.
