A red vial is typically used to draw a peak level, and a purple vial is used to draw a trough level when monitoring medication levels in the blood. It is important to follow specific guidelines provided by the laboratory for accuracy.
The color top commonly used for a Complete Blood Count (CBC) draw is lavender. This tube contains the anticoagulant ethylenediaminetetraacetic acid (EDTA) to preserve the blood sample and prevent it from clotting.
A blue-top tube (sodium citrate) is typically used to collect blood samples for Prothrombin Time (PT) testing.
For a PTT lab draw, a light blue top tube is typically used. This tube contains sodium citrate as an anticoagulant to prevent blood clotting during the test.
A green top tube (containing lithium heparin) is typically used to draw blood for digoxin level testing. Make sure to follow proper specimen collection procedures to ensure accurate results.

A light blue top tube, containing sodium citrate, is typically used to draw blood for a prothrombin time (PT) test. The sodium citrate helps prevent blood from clotting by binding to calcium in the sample, enabling accurate assessment of blood clotting time.
A lavender-colored tube is typically used to collect blood samples for iron level testing.
