Blood samples drawn in a random order risks additive carryover that can drastically alter the lab test result and how the patient will be managed!
This full-color poster, measuring 10" x 22" and laminated for protection and longevity, depicts the order in which blood collection tubes must be filled to prevent additive carryover from altering test results. The poster depicts tube stoppers representing the most commonly used tubes and includes text explaining their position in the order, as established by the Clinical and Laboratory Standards Institute (CLSI).
Intended for posting in outpatient draw stations and blood collection/processing areas frequented by phlebotomists and other healthcare professionals with blood collection responsibilities, this poster serves as a vivid and attractive reminder of this commonly overlooked blood collection principle.
Note: some facilities have conducted internal studies that prompt a different order of draw to be implemented than that depicted in this poster. Always follow facility policy.
