  1. What is the function of the centrifuge in specimen processing?

    Answer: To separate blood components by density using centrifugal force

    A centrifuge uses centrifugal force to separate blood into layers based on density.

  2. A laboratory technician notices that a chemistry analyzer's daily QC results have been gradually increasing over five days but remain within 2 SD. What does this suggest?

    Answer: A developing systematic error or trend

    A progressive trend of QC results consistently moving in one direction suggests systematic error even though individual results may be within limits.

  3. Which body fluid specimen is collected by lumbar puncture?

    Answer: Cerebrospinal fluid (CSF)

    Cerebrospinal fluid is collected by lumbar puncture between the L3-L4 or L4-L5 vertebrae.

  4. What does the term 'aliquot' mean in laboratory processing?

    Answer: A portion of a specimen transferred to a separate container for testing

    An aliquot is a measured portion of a specimen transferred from the primary collection tube into a secondary container.

  5. What is the primary difference between serum and plasma?

    Answer: Serum lacks clotting factors (especially fibrinogen); plasma contains them

    Serum is obtained from clotted blood and lacks fibrinogen and most clotting factors. Plasma retains all clotting factors.

  6. A laboratory receives a lavender-topped tube with visible clots. What should the technician do?

    Answer: Reject the specimen and request a recollection

    A clotted specimen in an anticoagulated tube must be rejected because clots consume platelets and trap cells, producing inaccurate results.
