Edx ordering guide

When ordering electrodiagnostic testing, the referral is most useful when it states the clinical question rather than only the test name. Include the suspected localisation, symptom distribution and duration, relevant comorbidities, anticoagulant use and any implanted cardiac device, since each changes how the study is planned.

Quick answer

When ordering electrodiagnostic testing, the referral is most useful when it states the clinical question rather than only the test name. Include the suspected localisation, symptom distribution and duration, relevant comorbidities, anticoagulant use and any implanted cardiac device, since each changes how the study is planned.

State the question, not just the test

"EMG/NCS bilateral upper extremities" tells the laboratory what to do but not what you are asking. "Rule out median neuropathy at the wrist versus C6 radiculopathy, right hand, six months, worse at night" lets the study be designed around the differential and extended intelligently if the first findings point elsewhere. At CNS the neurologist performing the study interprets it, so a stated question is acted on during the appointment.

Details that change the protocol

Anticoagulation and antiplatelet therapy affect needle examination planning. An implanted pacemaker or defibrillator changes stimulation technique. Diabetes, thyroid disease, chemotherapy exposure, alcohol history and B12 status all shape the interpretation of a polyneuropathy pattern. Prior studies are valuable for comparison, so send them if they exist.

Timing and expectations

Electrodiagnostic changes take time to develop after an acute injury, so a study performed very early can be falsely reassuring; discuss timing rather than ordering reflexively. Both CNS laboratories hold AANEM accreditation independently, and all six in-office studies are available at either office. The practice performs no surgery and operates no imaging suite. A brief note on what happens after the study: the report goes back to the referring clinician with the impression stated in words rather than only as tables of numbers, and the neurologist is available to discuss a result that does not fit the clinical picture. That conversation is often more useful than a repeat study.

About this practice

Clinical Neurology Specialists has been physician-owned since 1998, when Leo Germin, M.D., FAANEM founded it. Five board-certified neurologists and four advanced practice providers see patients at the Las Vegas and Henderson offices, each with its own AANEM-accredited electrodiagnostic laboratory.

Clinical Neurology Specialists is an adult outpatient neurology practice for patients 18 and older. The practice performs no surgery and operates no imaging suite, infusion suite or interventional pain programme, and provides no emergency or inpatient care.

The practice referral form is available as a PDF, and a Spanish version is available for patients who prefer it.

Emergency & crisis resources: Clinical Neurology Specialists is not an emergency service. For stroke symptoms, a seizure lasting more than five minutes or any medical emergency, call 911 or go to the nearest emergency room. For a mental health crisis, call or text 988 (Suicide & Crisis Lifeline).

Frequently asked

Questions about edx ordering guide

What should an EDX referral include?
The clinical question and suspected localisation, symptom distribution and duration, relevant comorbidities, anticoagulant or antiplatelet use, any implanted cardiac device, and prior studies for comparison. The clinical question is the single most useful line. Prior electrodiagnostic studies are worth sending even if they are several years old, because comparison over time changes the interpretation.
How is the study performed at CNS?
In the office, by the neurologist who will interpret it, in a laboratory holding AANEM accreditation in its own right at both locations. Because the same clinician performs and reads it, the protocol can be extended during the session when early findings redirect the question.
When should electrodiagnostic testing be ordered?
When localisation is uncertain and would change management: distinguishing focal compression from radiculopathy or polyneuropathy, confirming and grading a neuropathy, or assessing a suspected myopathy or neuromuscular junction disorder. It is a localising study, not a screening test. Timing matters after an acute injury, since electrodiagnostic changes take time to appear and a very early study can be falsely reassuring.
How do I send a referral?
The practice referral form is available as a PDF, and there is a Spanish version for patients who prefer it. Include the clinical question and the details above. Contact the office at 702-804-1212 if you need to discuss a case before referring.
Do you accept referrals for patients under 18?
No. This is an adult practice and patients must be 18 or older. Paediatric electrodiagnostic studies require a paediatric centre. The practice is adult outpatient neurology throughout, and that boundary applies to diagnostic testing as much as to consultation. Paediatric electrodiagnostic work needs a centre equipped and staffed for it.
