✔✔Average gauge of needle used for drawing blood - ✔✔21-22
✔✔3 skills of the phlebotomist - ✔✔social, clerical, technical
✔✔Analytical errors during collection of blood - ✔✔extended tourniquet time, hemolysis,
wrong order of draw, failure to invert tubes, faulty technique under filling tubes
✔✔Analytical errors before collection of blood - ✔✔Patient misidentification, improper
time, wrong tube, not fasting, exercise (cortisol levels), PT posture, poor coordination
with other treatments, improper side prep, medication interference

ensuring the accuracy of a test while detecting and eliminating error - ✔✔What is quality
control
✔✔Common test for the red topped tube - ✔✔Serum chemistry tests, serology tests,
blood bank (glass only)
