Module GLP-04 · Version 1.0

Order of Draw, Communication, and Special Collections

Work through the current venous order of draw, why additive carryover (not cap color) drives it, and how timing, chilling, light protection, and closed-loop communication keep a specimen defensible from needle to bench.

Who this module is for

Phlebotomists, medical laboratory scientists, and clinical laboratory staff who collect or receive venous specimens

Learning objectives

  • Explain additive carryover and use the current CLSI order of draw
  • Identify tests requiring discard tubes, timed stages, chilled or light-protected handling, or dedicated tubes
  • Use closed-loop communication for complex and interrupted collections

How completion works

Mark every required section done and answer every knowledge check in those sections correctly. The final save completes the module automatically.
