VARICELLA ZOSTER VIRUS IGG

The Varicella Zoster Virus (VZV) IgG test is a blood test that checks for the presence of antibodies against the VZV, which causes chickenpox and shingles. The test measures the level of IgG antibodies in the blood, which indicates whether a person has been infected with VZV in the past or has been vaccinated against it. A positive result means that the person has immunity to VZV and is protected against developing chickenpox or shingles. This test is particularly important for people who are at a higher risk of developing severe complications from chickenpox or shingles, such as pregnant women or those with weakened immune systems. A healthcare provider may recommend the VZV IgG test as part of routine screening or as a diagnostic tool to confirm suspected cases of VZV infection.
