Copyright © The McGraw-Hill Companies, Inc. Permission required for reproduction or display Chapter 342 Chapter 3 Summary All patient information must be included on the requisition form. All tube labels must include the patient’s name, date, time, and the phlebotomist’s initials. Computer information in phlebotomy are used to maintain patient data and results, receive orders and requisitions, and generate charges. Equipment needed for phlebotomy includes gloves, tourniquet, alcohol pads, gauze, bandage, needles, evacuated tube and holder, sharps container, marker, label, and evacuated tube(s).

Copyright © The McGraw-Hill Companies, Inc. Permission required for reproduction or display Chapter 343 Chapter 3 Summary (cont’d) Evacuated tubes are a closed system of collection that allow for multiple tubes to be collected in one venipuncture. Used equipment must be disposed of in a sharps container with a biohazard label. Evacuated tubes come in different colors with different additives. You should be familiar with the tube colors most commonly used at your facility.

Copyright © The McGraw-Hill Companies, Inc. Permission required for reproduction or display Chapter 344 Chapter 3 Summary (cont’d) The order of draw for evacuated tubes is blood culture or yellow tube, SST, serum, heparin, PST, EDTA, pink or lavender, and gray. The winged set includes a butterfly needle, small tubing, and a syringe. The syringe set may also be used. Dermal puncture is performed with a safety lancet or puncture device, collection tubes, and the same equipment used for venipuncture.
