TEST ID PLTAGG PLATELET AGGREGATION
Additional Codes
PLATELET FUNCTION
Performing Laboratory
NRLS-Core Coagulation
Specimen Type
Whole Blood
Specimen Required
Container/Tube:
Preferred: Blue Top Sodium Citrate 3.2%
Acceptable:
Specimen Volume: Full tubes
Collection Instructions:
Draw 2 full, 2.7 mL light blue-top (3.2% sodium citrate) of whole blood. Do not centrifuge
After sample collection, ensure proper mixing of anticoagulant by gently inverting the tube by hand 3 to 4 times. Venous collapse or stoppage of blood flow, use of needles <21 gauge or incorrect specimen collection techniques may cause small thrombi or hemolysis which will interfere with the test.
It is important that the collection tube is properly filled to the fill line indicated on the tube. Under-filled tubes will result in falsely prolonged values due to dilution of plasma with anticoagulant; and therefore cannot be processed.
Specimen Minimum Volume
