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.
A monospot test works by detecting certain proteins called heterophile antibodies. The body makes these proteins to fight the Epstein-Barr virus (EBV) or cytomegalovirus (CMV) -- the two viruses that cause mono (see Mononucleosis Causes).
