and my antibody  norma

QSART: Quantitative sudomotor autonomic reflex testing (qsart) is used to diagnose: painful small fiber neuropathy when nerve conduction test results are normal; disturbances of the autonomic nervous system, which controls the sweat glands, heart, gastrointestinal tract, other organs, and blood pressure; complex regional pain syndrome or reflex sympathetic dystrophy. A discussion with ur neurologist next. ...Read more

Receptor (Definition)

An organ, cell or molecule that accepts an outside signal and causes an internal change. Eyes receive light, touch receptors send messages to the brain when stimulated by pressure and estrogen receptors bind Estradiol causing responses of normal breast, ovary and uterus cells to rising and falling levels of the female steroid hormones. Most of the time "receptor" refers to one ...Read more

What other diseases can give the same symptoms as systemic myasthenia gravis when antibodies against the acetylcholine receptor are negative?

What other diseases can give the same symptoms as systemic myasthenia gravis when antibodies against the acetylcholine receptor are negative?

Anti-titin: There is a second type of antibody that is a perfect mimic. Eaton-Lambert antibodies are worth checking if you smoke. You may also be weak for other reasons, of if life's difficult, that itself can make you floppy and feel like you are getting MG. ...Read more

What are acetylcholine receptor antagonists and what are they used for?

What are acetylcholine receptor antagonists and what are they used for?

Neuromusculat ransmi: Acetylcholine is an import neuromuscular transmitter that controls muscle functions and bodily and organ movements inside. So using antagonists can block these processes and cause trouble especially with the function of our smooth muscles of the bowel(constipation)bladder(urine retention) and eyes(blurred vision). ...Read more

Tested for acetylcholine receptor ab panel; both binding and blocking were 0, but modulating came back at 10. Does this mean I have myasthenia gravis?

Tested for acetylcholine receptor ab panel; both binding and blocking were 0, but modulating came back at 10. Does this mean I have myasthenia gravis?

AchRAntibodies: Binding antibodies are the most sensitive--they are positive in over 80% of ms patients. Blocking antibodies are positive in about half. Modulating antibodies alone don't support the diagnosis and have a lot oof false positives. In summary the achreceptor antibody panel does not suggest that ou have ms>. ...Read more

What do acetylcholine receptors agonists do and what are they used for?

What do acetylcholine receptors agonists do and what are they used for?

different things: Agonists stimulate receptors while antagonists inhibit them. Most often we use the antagonist drugs in treating different diseases. However, those conditions that decrease sputum, sweat or tear production are sometimes treated with an agonist . Pilocarpine (an agonist) is used to treat glaucoma but by a different mechanism as mentioned above. ...Read more

Do ACh antibodies block or destroy ACh receptors ?

Do ACh antibodies block or destroy ACh receptors ?

Both in a way: ACh or acetylcholine antibodies can be both blocking and binding. They are nearly specific for Myasthenia Gravis. Binding essentially destroys the function. Acetylcholine is essential for nerve muscle and nerve nerve impulse transmission. ...Read more

Do you know if acetylcholine is considered an agonist for the cholinergic receptors?

Terminology: Why are cholinergic receptors called cholinergic receptors? You can apply acetyl choline to cholinergic receptors and see the physiologic changes. ...Read more

Could antibodies to the nmda-like receptors in the epidermis cause dysesthesias?

Dysesthesias: There is some data about nmda-receptor antibodies leading to encephalitis and inflammatory issues, but this would need to be discussed with your neurologist. ...Read more

What does the result of 'Low Positive' for an NMDA Receptor Antibody test mean?

What does the result of 'Low Positive' for an NMDA Receptor Antibody test mean?

Depends: Why was the test ordered? I would contact the Dr who ordered the test to explain the results to you. They know the clinical context. Low Positive can also mean not exactly positive or not clinically significant. ...Read more

Antibody (Definition)

An antibody is a protein the body's immune system makes to identify potentially harmful substances in the body. Antibodies attach to the substance on a molecular level and mark it so the immune ...Read more
