What are the causes of hematoma in venipuncture?
Venipuncture technique If the phlebotomist pushes the needle too far into and through the vein, blood leaks out of that opening and into the surrounding tissue. The appearance of a blue or purple discoloration at the venipuncture site indicates the presence of a hematoma.

- Use the major superficial veins.
- Make sure the needle fully penetrates the upper most wall of the vein.
- Apply pressure to the venipuncture site.

What should you do if a hematoma begins to form during venipuncture?
a. Hematoma: Blood can leak out of a vein and under the skin during venipuncture. This can cause discomfort and pain and can complicate further collections from that site. As soon as a hematoma is noted, remove the needle and tourniquet and apply pressure at the site for a minimum of 3 minutes.
What does cloudy plasma indicate?
Plasma that is cloudy looking is caused by increased levels of plasma triglyceride concentrations. This can occur if a donor has eaten a fatty meal before donating plasma, and it renders the donation unusable.
What does it mean when a blood sample is lipemic?
Lipemia is defined as visible turbidity in serum or plasma samples due to the presence of lipoprotein particles, especially chylomicrons. The most common cause of turbidity is a high concentration of triglycerides [1,2].
