This document outlines the objectives for Chapter 11 on special collections and point-of-care testing. It lists 37 key terms and their descriptions related to special specimen collection procedures and point-of-care testing. It also provides a matching exercise that matches point-of-care tests to the instruments used to perform those tests.

CHAPTER
11
Special Collections and
Point-of-Care Testing
OBJECTIVES
Study the
information in
your textbook
that corresponds
to each objective
to prepare
yourself for the
activities in this
chapter.
1 Defi ne the key terms and abbreviations at the beginning of this chapter.
2 Explain the principle behind each special collection procedure, identify the steps
involved, and list any special supplies or equipment required.
3 Describe patient identifi cation and specimen labeling procedures required for blood
bank tests and identify the types of specimens typically required.
4 Describe sterile technique in blood culture collection, explain why it is important,
and list the reasons why a physician might order blood cultures.
5 List examples of coagulation specimens and describe how to properly collect and
handle them.
6 Describe chain-of-custody procedures and identify the tests that may require them.
7 Explain the importance of timing; identify the role of drug half-life, providing
names of drugs as examples; and describe peak, trough, and therapeutic levels in
therapeutic drug monitoring.
8 Defi ne point-of-care testing (POCT), explain the principle behind the POCT
