What kind of problems could occur if that particular order is changed? and why is there a particular order? What kind of problems could occur if the order is changed?_ Twist the tip of the syringe needle in the center of the device to connect it to a blood transfer device. Fill a vacuum blood collection tube to the appropriate level and place it in the holder of the vacuum blood transfer device to the appropriate level and place it in the holder of the transfer device. To avoid cross-contamination between the different additives contained in blood collection tubes, international guidelines have established the following blood collection order: blood culture bottle, tube without additives, coagulation tube, clot activator, blood separator tube. plasma, ethylenediaminetetraacetic acid (EDTA), tube blood, and oxalate/fluoride.To avoid cross-contamination of the sample from additives found in various collection tubes, phlebotomists must draw blood samples in a specific order. For samples collected by syringe, tube holder, or in tubes pre-evacuated at the time of collection, the order of extraction is the same. All tubes containing an anticoagulant or preservative must be allowed to fill completely to ensure adequate test results. Attempts to push more blood into the tube by applying pressure, such as when using a syringe to draw blood, will damage the red blood cells (hemolysis). To acquire accurate biochemical results, the order of extraction must be followed. Blood samples taken by trained phlebotomists were free of EDTA contamination.Patient safety could be compromised if the order of extractions is incorrect. If the order of draw is not followed during syringe collection, contamination with K EDTA may occur. When drawing numerous specimens for clinical laboratory testing throughout a single venipuncture, the order of draw is recommended for both glass and plastic venous collection tubes. The goal is to avoid errors in test results caused by additive carryover. Fill all additive tubes to specified volume.Health Science Science Nursing MEA 1260C
