Common peroneal nerve dysfunction is a type of peripheral neuropathy (damage to nerves outside the brain or spinal cord). This condition can affect people of any age. Dysfunction of a single nerve, such as the common peroneal nerve, is called a mononeuropathy.
What Is a Mononucleosis Spot Test? A mononucleosis spot (or Monospot) test is a blood test used to determine whether or not you are infected with the Epstein-Barr virus, which is the organism that causes infectious mononucleosis. Your doctor may order this test if you have symptoms of mononucleosis.
The monospot test and the EBV antibody test are not used to diagnose or monitor CFS. Children, especially those younger than 2 years, are more likely than adults to have a negative monospot test, even when they have mono. This is called a false-negative result.
