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 mono test may be repeated at a later time and/or tests specific for EBV antibodies may be performed to help confirm or rule out the mononucleosis diagnosis. Most infants and young children will not make heterophile antibodies, so they will have negative mono tests even when infected with EBV.
