wrong order of draw, failure to invert tubes, faulty technique under filling tubes
Analytical errors before collection of blood - - ANS✔️--Patient misidentification, improper time,
wrong tube, not fasting, exercise (cortisol levels), PT posture, poor coordination with other
treatments, improper side prep, medication interference
Analytical errors after blood collection - - ANS✔️--Failure to separate serum from cell
(glycolisis), improper use of serum separator (not inverting tubes or not spinning tubes) delays in

accuracy of a test while detecting and eliminating error - - ANS✔️--What is quality control
Common test for the red topped tube - - ANS✔️--Serum chemistry tests, serology tests, blood
bank (glass only)
Order of draw for cappilary specimens - - ANS✔️--lavender first, then tubes with other additives,
then tubes with out additives
Antiseptic not used on a dermal puncture site - - ANS✔️--Betadine (because it interferes with
several tests like bilirubin, uric acid, phosphorus and potassium
