Lambert-Eaton myasthenic syndrome may be diagnosed by demonstrating the presence of specific antibodies in the blood that are directed against aspects of the presynaptic nerve, such as the calcium channels.
Diagnosis of multifocal motor neuropathy usually requires both a careful physical examination, as well as electromyographic (EMG) testing.
Accurate diagnosis of congenital myasthenia requires specialized testing. These include testing specific nerves to determine if the nerves fatigue more quickly than is normal
electromyographic examination and nerve conduction studies are often the most accurate means to localize and determine the exact nature and site of the plexopathy.
Myotonic dystrophy is diagnosed clinically in individuals that have a specific type of muscle weakness. This is confirmed with molecular genetics testing, where the DMPK is analyzed
Blood tests, neuroimaging studies, genetic tests, electroencephalography (EEG) and other types of studies may be performed in order to determine the underlying disorder.
Periventricular leukomalacia can be diagnosed through cranial ultrasound, which allows the brain to be examined using ultrasound techniques through the soft spots, or fontanelles, in the baby's skull
The child is often placed by an open window so he/she may be checked in natural light. Blood samples may be taken to determine the bilirubin level in the blood.
Tests that can be performed in the doctor's office include taking a blood pressure reading, recording the heartbeat (an electroencephalogram, or EEG), and obtaining blood for laboratory analysis
specialized testing can be done to determine if the virus is wild type (that is, it has been acquired from the environment), or whether it is a vaccine type (polio vaccines utilize intact, but weakened viruses).
It involves determining the effectiveness of giving oral bile acids (cholic acid, chenodeoxycholic acid, and ursodeoxycholic acid) as therapy for affected individuals.
the examination of blood by various techniques in order to demonstrate either yellow fever viral antigens (the part of the virus that stimulates the patient's immune system to respond) or specific antibodies
Answering your question fully will entail further research on my part.
