CMV - DNA test is one of the types of tests to check whether the Cytomegalovirus virus exists in the patient's body. Detection of this virus can be done by culturing the virus or detecting its genetic material (CMV-DNA).
1. Meaning of CMV-DNA test
CMV stands for Cytomegalovirus, this is a common virus and many people are infected, however, Cytomegalovirus rarely causes significant symptoms to the patient's health. In addition, Cytomegalovirus belongs to the same family of viruses as Epstein-Barr, herpes and varicella viruses that cause chickenpox and shingles.
In subjects with CMV virus, the virus can be found through urine, blood, saliva, semen, cerebrospinal fluid or vaginal secretions, etc. However, usually after primary infection, The CMV virus remains dormant for life without causing symptoms, unless the body's immune system is severely weakened.
CMV - DNA test is one of the types of tests to check whether the Cytomegalovirus virus exists in the patient's body. Detection of this virus can be done by culturing the virus or by detecting the genetic material of this virus (CMV DNA).
CMV - DNA test is the traditional diagnostic method to detect viruses. The presence of the virus can be detected as early as 1 to 2 days. However, when cultures are all negative for the virus, it should be repeated after 3 weeks for the purpose of accurately diagnosing CMV virus in the body, as the virus may be present in very low numbers or as a slow-growing CMV virus.
Because the disease does not affect the health of adolescents and healthy people too much, most cases of CMV testing are pregnant women, immunocompromised people or people who need an organ transplant. Because these subjects are potentially dangerous when catching this virus.
2. When to test for CMV-DNA
CMV testing should be performed in the following cases: CMV-DNA testing of patients with suspected CMV virus infection When CMV infection is suspected, testing should be performed on patients with CMV infection. Suspected patients with this virus infection are those with weakened immune systems (immunocompromised individuals with signs and symptoms of influenza, mononucleosis with signs such as fatigue, weakness, fever, swollen lymph nodes, pneumonia, hepatitis, spleen inflammation...); organ transplant, ...
CMV virus testing for pregnant women CMV testing is really essential for pregnant women, because any presence of IgM antibodies whether it is very small, it can be the reactivation of the virus and transmission to the fetus.
Therefore, if a new infection is detected in the first trimester of pregnancy, the doctor will consider ordering amniocentesis to test the fetus for CMV virus infection.
Testing of newborns born to mothers infected with CMV In case if the doctor suspects that the newborn has congenital CMV infection, it is necessary to test for CMV during the first 3 weeks after birth. Early testing aims to conclude whether the baby has a congenital viral infection or a viral infection from the surrounding environment.
Most infants infected with CMV virus at birth may have hearing or vision problems, mental retardation a few months after infection. Meanwhile, there are some babies who may die right after birth or have symptoms such as jaundice, anemia, and small heads.

3. CMV . test results
In the case of a person with clinical symptoms of CMV infection and a positive cytomegalovirus culture, an active CMV infection can be concluded. If cytomegalovirus cultures are negative, clinical symptoms may be due to another cause or because the amount of CMV virus in the sample is too low to detect disease.
Depending on the CMV test results, the doctor will recommend different testing methods as well as treatment or health protection. However, monitoring the effectiveness of treatment as well as reducing the viral load will reflect the response to antiretroviral therapy or not. Because levels that do not decrease with antiretroviral therapy may reflect the virus's resistance to the treatments used.
In summary, testing for CMV virus is very necessary for pregnant women or people with immunodeficiency syndrome as well as those with weak immune systems such as children and the elderly. Early detection of CMV virus will help doctors prescribe treatment methods, thereby limiting the serious consequences caused by this virus. Especially for pregnant women, the early detection of CMV virus will provide appropriate treatment methods, limit the virus infection and birth defects to the fetus caused by the virus.
