| Lavender top tube 3 mL (EDTA) | Light Blue top tube 2.7 mL (Na Citrate) |
Minimum:
Full draw; 3.0 mL lavender top; (or fingerstick)
Testing Schedule:
24 hrs/day, 7 days a week, including holidays.

Time:
Routine turnaround time is approximately 1 hour.
Reference Range:
150-400 k/mm3 Critical value: ≤10 k/mm3 and ≥1000 k/mm3
Comments:
For patients who repeatedly have platelet clumps which preclude
determination of an accurate platelet count, it is now possible to
order a platelet count from a citrate tube. In many cases the EDTA in
a lavender top tube causes the platelet clumping which does not occur
in a blue top (citrate tube). Use order code PLTB to order the
Platelet Count, Blue Top (Citrate) Tube. The Epic order code is
LAB7882. This test is available 24 hours a day, 7 days a week. This
test cannot be done on a citrate tube drawn for coagulation
testing.
This test is also performed in the Iowa River Landing (IRL) clinical laboratory (for specimens drawn at that site).
