About your past

This schedule is 7 to 3:30 with every other weekend at Delnor. How does that work for you?

What would you do
A specimen arrives with a label that does not match the requisition. What do you do?

Home health specimens come in all at once at the end of the day. How do you register them accurately when you are rushed?

You are unsure how to handle an unusual specimen. Who do you ask, and what do you do in the meantime?

How do you check that the right tube, container and volume came in for the test ordered?

What waived tests have you performed, and how do you make sure your results are reliable?
What they are checking: Whether they understand quality control for waived testing under CLS direction.
How do you keep track of specimens so none get lost between receiving and the testing area?
What they are checking: Whether they have a system for distribution and tracking that prevents lost specimens.
