Which microcollection container should be collected first?

Microcontainer collection order of draw differs from regular peripheral blood collection order of draw. When performing a capillary draw, the lavender top container is obtained first. This decreases the possibility of clots in the container which would invalidate the results of the complete blood count test.

After the lavender is drawn, other containers with anticoagulants would be collected, and containers without anticoagulants would be collected last.

A phlebotomist must perform a skin puncture to obtain capillary specimens for a complete blood count (CBC), a plasma-based chemistry test, and a serum-based immunology test. The microcollection containers that will be used are lavender top containing EDTA anticoagulant, green top containing heparin anticoagulant, and gold top containing no anticoagulant.

Which microcollection container should be collected first?
A . Lavender top
B. Green top
C. Gold top
D. The order of draw is not important.
