Electromyography and nerve conduction studies are performed to give the doctor information about how the nerves are conducting impulses to the spinal column.

A neurologist usually administers nerve conduction tests. During this test, electrodes are placed at various spots along the nerves in the legs and feet. Both sensory and motor nerves are tested at different locations. Electrical impulses are sent through the nerve and the speed and intensity at which they travel is measured. If there is compression in the tunnel, this can be confirmed and pin pointed with this test. See similar questions...

There are 4 possible test results: "negative", "positive", "indeterminate", or "result not available." A "negative" test result means antibodies to the hepatitis C virus were not found in your test sample and it is extremely unlikely that you have been infected with the hepatitis C virus.

I took a fall at home in January. Hurt my neck up high. Slowly, I got weakness in arms with uncoordination, then in the legs, with fasciculations, weakness and heaviness. There are 2 kinds of nervous system; central nervous system (CNS) and peripheral nervous system (PNS). The CNS consists of brain and spinal cord. EMG has no role in diseases or lesions of CNS.

Nerve interference shows up in the form of headaches, radiating pain, numbness, weakness in your arms or legs, and on and on. In light of the fact that every muscle, organ and sensory is controlled by the nervous system it open a lot of possibilities up for some adverse effects if the nervous system is irritated in some way.

There are three nerves that lie close to the submandibular gland that can be damaged during its removal. Most nerve damage occurs as a result of bruising of the nerves since they are held out of the way and protected during surgery. If nerve damage occurs it is usually temporary.

STAR assessments gain you no certifications but acknowledges the completion of a test in a certain area of knowledge. Upon completion of a STAR assessment test, you will have access to a complete skills summary screen (Report Card) documenting your performance in each subject area that you can view or print.

A positive TB test means that someone has been exposed to the TB germ and follow up evaluation is needed. Once a positive TB test has been confirmed to be truly positive, there is no point in having repeat TB tests in the future. They will not hurt you, or cause disease, but will always continue to be positive. BCG vaccine (Bacille Calmette-Guerin) used in countries where TB is endemic, can decrease the severity of TB in children but will not prevent TB infection. See similar questions...

You can take your medication as you regularly would in the morning and eat regularly. It is advised that if you shower the night before or that morning (or bathe) that you do not put any creams or lotions on your skin (in particular the areas that are going to be studied). Please advise us if you have a pacemaker, are taking a medication called Coumadin, or have any communicable diseases such as hepatitis B or C, or HIV infection. See similar questions...

The letters EMG represent "electromyography," which refers to the measurement of muscle electrical activity. As muscles contract, microvolt level electrical signals can be measured from the skin's surface. Electromyography is the study of muscle activity through the measurement of these electrical signals. Researchers and clinicians use surface EMG to more accurately evaluate muscle function and activity. See similar questions...

No, even though a gene mutation may be present, you are not at 100% risk for developing cancer. An individual with a BRCA1 and/or BRCA2 alteration is more likely to develop cancer than an individual without an alteration. However, not every individual who has a BRCA1 and/or BRCA2 alteration will develop cancer, because genes are not the only factor affecting cancer risk. See similar questions...

No. The test for HIV can only tell you if you have been infected or not. Transmission of the virus does not necessarily occur every time exposure occurs. The only way for an individual to tell if he/she has been infected with HIV is to be tested. If you are unsure of your partner's status, you may want to consider talking to him/her about it and using protection (latex condoms or dental dams) to reduce your risk. See similar questions...

A positive antibody test could mean one of two things. It could mean that a person is infected with hepatitis C and is a chronic carrier. Or, it could mean that the person was infected with hepatits C but has cleared it from his or her body. An antibody test cannot tell anyone which of those two categories applies. Once infected, you will always have hepatitis C antibodies, and therefore will always test positive on a hepatitis C screening test. See similar questions...

The most commonly used syphilis tests screen for an antibody to the syphilis organism. Lupus patients sometimes have a very similar antibody. This similar antibody, the antiphospholipid antibody (aPL), can cause an incorrect positive result on a syphilis test. If the doctor suspects that the patient may not really have syphilis, he may choose to then run a different, more complicated and expensive test that checks specifically for the syphilis organism. See similar questions...

A false positive hearing screening test result is when a baby does not have a hearing loss but the newborn does not pass the hearing screening. Hearing screening tests are not meant to diagnose hearing loss in infants. Instead, they are meant to find all infants that might have a hearing loss. Because they are not a diagnostic test, hearing screening tests sometimes misidentify infants as having a hearing loss. See similar questions...

Not usually. Most teeth that need a root canal have a living nerve that is inflamed and causing pain from cold and/or heat. Other teeth have a nerve that has gone through and past the inflamed stage and has died and decomposed. The percentage of teeth with a dead nerve is actually in the minority. A nerve MUST die before it can become abscessed (infected) because the bacteria need a food source on which to thrive. A living nerve does not provide a food source like a decomposed one.

Sensors placed on the skin directly above the muscles detect the small electric potential, or signal, which comes from active muscles. The strength and pattern of the signal is displayed on a computer screen and the data is collected in a software program that is able to run various analyses of the data to create useful reports regarding muscle function. See similar questions...

The full name is the pudendal nerve distal motor latency test. As the "Consensus Statement of Definitions for Anorectal Physiology and Rectal Cancer" for the United States defines it: quot;Pudendal nerve latency is the measurement of the time from stimulation of the pudendal nerve at the ischial spine to the response of the external anal sphincter. Normal pudendal nerve terminal motor latency is <2.2 ms." - Source This means the normal response time should be 2. See similar questions...

Some preliminary testing results are usually given to you, but a detailed discussion and proper counseling as to the testing results will be done by the physician who referred you for the study. See similar questions...

If you do not choose to take any medication for the test which is what most individuals prefer, there are no restrictions in driving to and from the test. See similar questions...
