Specially designed blood culture collection bottles eliminate the need for either the syringe or butterfly collection method. These specially designed bottles have long necks that fit into the evacuated tubes holders that are use for regular venipuncture collection.
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 ]
A venipuncture performed using a vacutainer. A venipuncture is useful as it is a minimally invasive way to obtain cells and extracellular fluid from the body for analysis.. Blood flows throughout the body, acting as a medium that provides oxygen and nutrients to tissues and carries waste products back to the excretory systems for disp
Blood collection tubes are among the basic medical supplies taken by disaster relief programs to affected areas. Vacutainer technology was developed in 1947 by Joseph Kleiner, [2] and is currently marketed by Becton Dickinson (B-D). [16] The Vacutainer was preceded by other vacuum-based phlebotomy technology such as the Keidel vacuum.
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. [2] Blue ("light blue") Sodium citrate (weak calcium chelator ...
The tubes have micronized silica particles which help clot the blood before centrifugation, and a gel at the bottom which separates whole blood cells from serum. [1] Silica nanoparticles induce coagulation through contact activation of coagulation factor XII (Hageman factor). [ 2 ]
Butterflies are commonly available in 18-27 gauge bore, [1] 21G and 23G being most popular.. In phlebotomy, there is widespread avoidance of 25G and 27G butterflies based on belief that such small-bore needles hemolyze and/or clot blood samples and hence invalidate blood tests. [2]
Capillary blood sampling, generally by using a blood lancet for puncture, followed by sampling by capillary action with a test strip or small pipe. This is common for routine diabetic monitoring for glucose. Venous blood sampling, also called phlebotomy. It is generally done by venipuncture (which can also be used for intravenous therapy).
