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.
Specifically, the mono spot test is used to detect antibodies to EBV antigens. You may not have a detectable level of antibodies early in the illness. If this occurs, the test may need to be repeated in 10 to 14 days.
