This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - A discard tube is required for a light blue (coagulation) top tube when it is the first or only tube drawn with a straight needle to clear tissue thromboplastin. - When using a winged (butterfly) collection set, a discard tube must be drawn before a light blue top tube if it is the first tube in the sequence. - The purpose of the discard tube with a butterfly needle is to purge the air from the tubing, ensuring a proper 9-to-1 blood-to-anticoagulant ratio. - Discard tubes are generally not required for routine chemistry or hematology tubes when they are drawn first. - Remember the mnemonic: "Blue needs a buddy when it's first in line or using a butterfly" to recall the two key scenarios requiring a discard tube.
