Study Notes
Reminders for Blood Specimen Collection
- Collect blood specimens using the correct order of draw to prevent cross-contamination from tube additives.
- Invert tubes containing additives immediately after collection.
- Label tubes appropriately with patient's full name, unique identification number, date and time of collection, phlebotomist's initials, and compare with patient's identification bracelet.
Order of Blood Draw
- Blood culture tube (Yellow Top) - 8 inversions
- Citrated tube (Light Blue Top) - 3-4 inversions
- Serum tube (Red Top glass) - 0 inversions
- Serum tube (Red Top plastic) - 5 inversions
- Heparinized tube (Green Top) - 8 inversions
- EDTA tube (Lavender/Purple/Pink Top) - 8 inversions
- Sodium fluoride tube (Gray Top) - 8 inversions
Other Blood Collection Tubes
- Black Top: Contains 3.8% sodium citrate, blood to anticoagulant ratio 4:1, used for Westergren ESR.
- Pink Top: Requires a special label, contains K2 EDTA, and can be used for a, 3.2% sodium citrate, or b, Citrate, Theophylline, Adenosine, Dipyridamole. Use cases include Blood Bank Studies and Whole blood Hematologic determinations.
- Light Blue Top: may contain either 3.2% sodium citrate or Citrate, Theophylline, Adenosine, Dipyridamole. Uses include coagulation tests, platelet factor 4, and beta-thromboglobulin assays, and in Gray platelet syndrome.
