Hemoconcentration
a decrease in the fluid content of the blood with an increase in nonfilterable large molecules or protein-based blood components. Caused by overuse of tourniquet, heavy massaging of draw site, drawing blood from sclerosed or occluded veins, and vigorous hand pumping
Hemolysis
occurs when damaged or destroyed RBC leak hemoglobin in the fluid portion of the blood sample. Caused by drawing blood through a hematoma, failure to transport specimens in a correct manner, probing to find a vein, mixing tubes too vigorously, using a needle that is too small during venipuncture, etc ( Box 9-3 on p 293)
Other ways that can lead to specimen compromise

How is your blood type determined
depends on which RBC antigen ( A, B, or O), which plasma antibody (Anti A, or B), and whether you have the Rh blood group present in your blood.
Serum
the liquid that remains after blood has been clotted. does not contain fibrinogen
Plasma
the fluid part of the blood used for testing that contains fibrinogen
Needle Gauge
the number that indicates the diameter of the lumen. the smaller the number bigger the diameter of the needle. The most common needle gauges are 20-23.
Order of Draw for Normal Venipuncture Procedure
