Tubes containing gel can be easily handled and transported after centrifugation without the blood cells and serum mixing. Vacutainer blood tubes. The meanings of the various colors are standardized across manufacturers. [5] [6] [7] The term order of draw refers to the sequence in which tubes should be filled. The needle which pierces the tubes ...
Tube cap color or type in order of draw Additive Usage and comments Blood culture bottle: Sodium polyanethol sulfonate (anticoagulant) and growth media for microorganisms: Usually drawn first for minimal risk of contamination. [1] Two bottles are typically collected in one blood draw; one for aerobic organisms and one for anaerobic organisms ...
Blood glucose monitoring. In medicine, some blood tests are conducted on capillary blood obtained by fingerstick (or fingerprick) (or, for neonates, by an analogous heelprick). The site, free of surface arterial flow, where the blood is to be collected is sterilized with a topical germicide, and the skin pierced with a sterile lancet. [1]
Capillary blood sampling can be used to test for blood glucose (such as in blood glucose monitoring), hemoglobin, pH and lactate. [ 30 ] [ 31 ] It is generally performed by creating a small cut using a blood lancet , followed by sampling by capillary action on the cut with a test strip or small pipette . [ 32 ]
A blood gas test or blood gas analysis tests blood to measure blood gas tension values and blood pH.It also measures the level and base excess of bicarbonate.The source of the blood is reflected in the name of each test; arterial blood gases come from arteries, venous blood gases come from veins and capillary blood gases come from capillaries.

A phlebotomy draw station is a place where blood is drawn from patients for laboratory testing, transfusions, donations, or research purposes. The blood is typically drawn via venipuncture or a finger stick by a healthcare professional such as a phlebotomist , nurse , or medical assistant . [ 21 ]
Electrophoresis is a laboratory technique in which the blood serum (the fluid portion of the blood after the blood has clotted) is applied to either an acetate membrane soaked in a liquid buffer, [3] or to a buffered agarose gel matrix, or into liquid in a capillary tube, and exposed to an electric current to separate the serum protein ...
