CASE STUDY 6-2: CIRCULATORY SYSTEM DISORDERS, DIAGNOSTIC TESTS, AND VEIN SELECTION A phlebotomist receives a request to collect a specimen for a PT and D-dimer on a patient. The phlebotomist remembers drawing the patient in the ER when he was complaining of leg pain. Because the patient was a difficult draw, the phlebotomist wanted to draw from an ankle vein, but the physician would not give permission. The patient was subsequently diagnosed with DVT.. When the phlebotomist received the next request on this patient, he still couldn't find a good vein in the AC area, but he noticed that the patient had a large vein on the underside of the wrist. Before he could collect from the wrist area, he was called to a STAT in the ER. Questions 1. Should the phlebotomist draw from the vein on the underside of the wrist? Why or why not? 2. What do PT and DVT mean? 3. Which body process is being evaluated by the requested tests? 4. What type of specimen is required: serum, plasma, or whole blood! 5. Give a reason for your selection of specimen type.
