diameter

Multisample needles are typically available in these guages.

20-22

The slanted tip of the needle is called the:

bevel

The purpose of the rubber sleeve that covers the tube end of a multi-sample needle is to:

microbiology

A royal blue top with green color coding on the label contains:

heparin

What substance is an anticoagulant:

oxalate

It is important to fill oxalate tubes to the stated fill capactiy because excess oxalate:

causes hemolysis of blood specimens

This substance in contained in a serum separator tube?

there is a permanently attached needle with a sleeve inside the transfer device

A prothrombin time (PT) and platelet count are ordered on an 80-year-old female patient. Deciding to use a butterfly and "short draw" evacuated tubes on the tiny cephalic vein on the dorsal side of the right arm, the phlebotomist collects the light blue tube first and the lavender last. Why would you suspect that the PT test results might be incorrect and the platelet count unaffected.

no tube was drawn to remove air in the butterfly tubing
