This test is done if your caregiver suspects you presently have or have had a CMV (cytomegalovirus) infection. It is also done if you are in a clinical situation where it is important to know your CMV status, such as before surgery or organ transplant. It is sometimes done when a young adult, a pregnant female, or an immune-compromised patient has flu-like symptoms that suggest a CMV infection; or if a newborn has multiple congenital anomalies, unexplained jaundice or anemia, and/or if an infant has seizures or developmental problems that may be due to CMV.
Testing involves either a measurement of CMV antibodies (specific proteins created by the body's immune system in response to the virus) or the detection of the virus itself, through culturing and growing the virus or by amplifying the genetic material from the virus itself.
A blood sample is drawn from a vein in your arm for CMV antibody testing. To detect the virus itself, the sample may be blood, urine, or sputum, amniotic fluid, cerebrospinal fluid, duodenal (from the intestines) fluid, or other body tissue.
Negative growth, No virus located
Ranges for normal findings may vary among different laboratories and hospitals. You should always check with your doctor after having lab work or other tests done to discuss the meaning of your test results and whether your values are considered within normal limits.
MEANING OF TEST
Your caregiver will go over the test results with you and discuss the importance and meaning of your results, as well as treatment options and the need for additional tests if necessary.
OBTAINING THE TEST RESULTS
It is your responsibility to obtain your test results. Ask the lab or department performing the test when and how you will get your results.
