Reporting a Study You Cannot Interpret Confidently
You are the only technologist on a Saturday shift. A 71-year-old inpatient with diabetic neuropathy is sent for upper- and lower-limb nerve conduction studies. Midway through, the referring resident calls and asks you to "just give me the diagnosis now" because the patient is being discharged in an hour. You have completed lower-limb motor studies showing absent peroneal and tibial responses and low-amplitude sural sensory responses, but you have not done upper-limb studies, needle EMG, or reviewed the chart. The patient's blood glucose is 340 mg/dL and he has bilateral foot ulcers. The supervising physician is off-site and reachable by phone.
1. What may you communicate to the resident, and what must you not do?
Read the worked answer
May communicate: factual, descriptive findings that are already recorded - for example, that lower-limb motor responses were absent and sural sensory amplitudes were low - while making clear these are preliminary and that the study is incomplete and has not been interpreted by the supervising physician.
Must not do: provide a diagnosis, a definitive interpretation, or treatment advice. Technologists are not credentialed to render diagnoses; that responsibility belongs to the supervising physician. You must not speculate that the findings "mean" diabetic neuropathy, because the absent responses could reflect the ulcers, edema, temperature, or technical factors, and the upper limbs and needle EMG are not done.
Also: document the request and your response, and contact the supervising physician to report the situation.
2. How do you handle the incomplete study, the patient's condition, and the documentation?
Read the worked answer
Incomplete study: call the supervising physician, describe what has been completed and what remains, and ask whether to complete the upper-limb and needle portions now or reschedule. Do not release an interpretation you are not authorized to give.
Patient condition: the glucose of 340 mg/dL and foot ulcers matter - open ulcers are a reason to avoid placing electrodes or needles near the lesions, and poor glycemic control can affect nerve function and comfort. Check skin integrity before any further electrode placement, maintain hygiene, and document the ulcers as a limitation if they prevent testing.
Documentation: record the studies performed, the technical factors (temperature, edema, ulcers), the resident's request and your response, the time you contacted the supervising physician, and the plan. If the study cannot be completed before discharge, state that clearly and recommend outpatient completion.
Professional standard: the correct action is to protect the patient and the integrity of the report, not to satisfy a discharge deadline with an unsupported diagnosis.
