How does Sodium Citrate work? - Sodium Citrate prevents coagulation by
binding to calcium in the specimen. It is the additive used for coagulation
studies because it preserves the coagulation factors in the specimen. It is a
liquid additive that requires specific blood to additive ratio: 9 parts blood to
1 part additive.
*Remember: Sodium Citrate is the additive in the Light Blue Top Tube.
True or False: The light-blue top tube must be filled completely to avoid an
inadequate ratio of additive to blood. - True; it must be drawn to the fill line.

For the Light Blue Top Tube, after the sample is collected, how many times
must it be inverted? - It must be inverted 3-4 times to mix blood and
additive properly.
True or False: Current CLSI standards mandate for the phlebotomist to
draw a red top tube before a light blue top tube, even though the requisition
does not call for it. - True
Why do current CLSI standards mandate for the phlebotomist to draw a red
top tube before a light blue top tube, even though the requisition does not
call for it? - This is to prevent thromboplastin released by the tissue cells
during venipuncture from entering the light-blue tube or to clear the line of
air when using a winged infusion set. Both thromboplastin and air can
affect the coagulation study results.
