Chickenpox and Shingles Tests
What Are Chickenpox and Shingles Tests?
Chickenpox and Shingles tests are diagnostic tests used to identify whether or not a person is infected with the varicella-zoster virus (VZV), the same virus responsible for chickenpox and shingles. The tests usually involve collecting a sample of fluid or cells from the body, such as a blood sample or tissue scraping from a rash, and then examining them under a microscope.
Preparation For Chickenpox and Shingles Tests
No specific preparation is generally needed for a chickenpox or shingles test. Your doctor may ask you questions about any prior or current infections that you may have had, as well as any medication or immunizations that you have had in the past.
Procedure for Chickenpox and Shingles Tests
The procedure for a chickenpox or shingles test typically involves collecting a sample from the body, such as a blood sample or skin scraping from a rash. The sample is then sent to a laboratory for analysis. In some cases, a biopsy may be taken. Results of the test are usually available in a few days.
Types of Chickenpox and Shingles Tests
- Polymerase chain reaction (PCR) tests - these tests can detect the presence of VZV in a sample of fluid or cells from the body, such as a blood sample or tissue scraping from a rash.
- Antibody tests – these tests measure the levels of antibodies in the blood that are produced in response to an infection with the VZV virus.
- T-cell tests – these tests measure the levels of a type of white blood cell called a T-cell, which fights against infections from viruses like VZV.
- Skin biopsy – this test involves removing a small piece of skin for examination under a microscope. It can be used to check for the presence of the virus in skin lesions associated with chickenpox or shingles.
Risks of Chickenpox and Shingles Tests
Chickenpox and shingles tests are generally safe and carry minimal risk. If you are concerned about any potential risks of the tests, be sure to discuss these with your doctor before the tests are performed.
Why Are Chickenpox and Shingles Tests Performed?
Chickenpox and shingles tests are used to confirm a diagnosis of VZV, since the symptoms of these infections can often be similar to other illnesses. They can also help to monitor how the body is responding to treatments and track the course of the infection.
When Are Chickenpox and Shingles Tests Performed?
Chickenpox and shingles tests are typically performed when a person is suspected of having been infected with the varicella-zoster virus. These tests may also be used to monitor the progress of the infection and the effectiveness of treatments.
