Obtaining a Serum (Blood) Lab Result
- The lab order is placed by a physician
- The nurse draws the blood into specific vials used for each lab study
- The tubes are placed in plastic bags, and delivered to lab
- The lab tech runs the samples through analysis machines
- After the machine produces the results the lab tech loads the results into an electronic system, making the results available to view.
Hemolyzed sample
The blood cells have broken down, which may skew some results of the blood sample. If a sample is hemolyzed the nurse must often “re-draw” the blood and send another sample to lab. Alert your physician as soon as possible if a blood sample ever results as “hemolyzed”.

Consultations 3 reasons
- The ED doctor needs to admit a pt to the hospital
- The ED doctor needs specialist advice regarding a particular disease, treatment, or need for follow-up
- The ED doctor calls the pts PCP to inform them their pt was evaluated in the ED.
Re-evaluations 5 reasons
- The pt is about to be discharged and doctor needs to share discharge instructions, ensure the pt’s Sx improved and is ready for discharge
- The pt is about to be admitted and the doctor needs to update the pt on the plan to admit, and check on the pt’s Sx and status.
- The pt needs abnormal vital signs re-checked
- A particular physical exam finding needs to be re-checked
- The doctor needs the determine if particular treatment was effective
