Draw one green top (sodium or lithium heparin) or lavender top (EDTA) vacutainer tube.
Yellow top (ACD soln A or B )tubes are also acceptable but tube must be appropriately filled (because of liquid anticoagulant) to preserve sample integrity.
Handling: Do not centrifuge! Keep at room temp (18-22°C).
Preferred volume: 4 mL
Minimum volume: 1 mL blood
Frozen, clotted, hemolyzed, spun down, citrate anticoagulant (blue top)
Maintain and transport specimens at room temperature (18-22°C).
Ship specimens Priority Overnight via Fed Ex in container sufficiently insulated to avoid temperature extremes (<10°C and >37°C).
48 hours at room temperature (18-22°C).
CBC with Differential results from within 3 days of draw must also be provided or a lavender top included with required specimen to run CBC at ADx.
Samples are accepted Monday through noon on Friday.
