The Cytomegalovirus (CMV) PCR, QN, Plasma test measurably detects CMV DNA in blood samples to assist in diagnosing and managing CMV infections. CMV is a prevalent virus in the Herpes family that can affect people of all ages. The CMV virus is also associated with viruses that cause chickenpox and infectious mononucleosis (mono). Most of the time, people infected with the virus do not experience any symptoms or show signs of an infection. However, symptoms can become active in certain situations, such as stress or an immune system problem.

A healthy individual may experience mild, flu-like symptoms or no symptoms if infected with CMV. However, people with weakened immune systems, recent organ transplant patients, or pregnant women have a higher risk for further health complications if infected with CMV.

Individuals may order this test if they have a weakened immune system, are pregnant, or are experiencing the following symptoms:

  • Swollen lymph nodes
  • Sore throat
  • Fever
  • Fatigue
  • Weakness
  • Muscle aches
  • Headaches

This test is best used to help confirm the results of a CMV antibody test, diagnose a current, reactivated, or past CMV infection in people at risk for health complications, determine the severity of the infection, or monitor treatment. Contact your doctor or healthcare provider if you have significant concerns or questions about your recent lab results.
