Cytomegalovirus Antibodies, Qualitative, IgM
(CMV)

Sample type:

• Serum.

Uses:

• To diagnose a current, past or reactivated cytomegalovirus (CMV) infection or if it is important to know if you ever had a CMV infection, such as prior to receiving an organ transplant.

Precautions:

• The sample required depends on the type of testing.

• For CMV antibody testing, a blood sample is drawn from a vein.

• To detect the virus itself, in patients who are symptomatic, the sample may be blood, urine, sputum, amniotic fluid, cerebrospinal fluid, duodenal fluid, other body tissues, or saliva in newborns.

• Some samples, such as amniotic fluid, cerebrospinal fluid, or body tissue (biopsy), may require a special procedure to collect.

• Your healthcare provider may also order a test called polymerase chain reaction (PCR) to hunt for the DNA of CMV in your urine, saliva, blood, CSF, or biopsy tissue. He or she may also order a viral culture test from any of these sample types.

Interfering Factors:

• Taking antibiotics or other medicine before doing the test. This will affect the result of the test.
