Wrap lavender top tube in foil to protect from light. Allow SST to clot and centrifuge within one hour of collection and transport in original tube. Transport all specimens within 24 hours of collection.
Limited by the urinalysis, which should be tested within 24 hours of collection, or 72 hours in a urine preservative tube (available upon request).

0.4 mL EDTA (royal blue) whole blood, 1.5 mL EDTA (lavender) whole blood, 1 mL serum (SST), and 1 mL urine.
WBC and platelet count may decline after 24 hours; 48 hours maximum delay. See also: Lead Exposure Follow Up (10610). Lavender top tubes (EDTA) may not be lead free. Elevated results will require a redraw using a royal blue top tube (EDTA) (lead free).
