How do I read my herpes test results?
Interpreting Results The results of your HSV blood test will generally be reported as either: Positive: IgG detected. Negative: IgG not detected. Equivocal: Results unclear.
What are the numbers for a positive herpes test?
0.80 – 0.99: Equivocal-Repeat in 10-14 days may be helpful. Greater than 0.99: Positive – May indicate a current or previous HSV infection. 0.90 – 1.09 IV: Equivocal – Repeat testing in 10-14 days may be helpful. Greater than 1.09: Positive – May indicate a current or recent infection.
What are the two types of herpes tests?
PCR finds the genetic material ( DNA ) of the HSV virus. This test can tell the difference between HSV-1 and HSV-2. Using the PCR test on skin sores isn’t common. PCR is used mainly for testing spinal fluid in rare cases when herpes may have caused an infection in or around the brain.
What are the ways to test for herpes?
If you have blisters or sores, your doctor or nurse will gently take a sample of fluid from the sores with a swab and test it. If you don’t have any sores, talk with your doctor or nurse about whether a blood test for herpes makes sense for you. But herpes tests aren’t normally recommended unless you do have symptoms.
What does a high herpes IgG level mean?
A positive HSV IgG blood test indicates that herpes immunoglobulin G is present. This means the person is carrying the herpes virus. An HSV IgG test will not be positive in the early stages of an infection.
What is the difference between IgG and IgM herpes test?
IgG tests are preferred because: For herpes, IgG and IgM antibodies show up around the same time — normally, IgM antibodies appear first. IgM antibodies may only last a few months and may not be made after the first outbreak — but IgG antibodies last indefinitely and are made during all outbreaks.
What does high HSV-1 IgG mean?
A positive test means you have been infected with HSV recently or at some point in the past. Tests can be done to help determine if you have a recent infection. About 70% of adults have been infected by HSV-1 and have antibodies against the virus.
What is considered a low positive for HSV-2?
If HSV-2 IgG type specific antibodies patient results fall between 0.91 (equivocal) and 5.00 (low positive) index values, the specimen will reflex to HSV-2 supplemental test per CDC guidelines.
What is the normal range of HSV-1 IgG?
0.89 IV or less: Negative – No significant level of detectable HSV IgG antibody. 0.90-1.09 IV: Equivocal – Questionable presence of IgG antibodies. Repeat testing in 10-14 days may be helpful. 1.10 IV or greater: Positive – IgG antibody to HSV detected which may indicate a current or past HSV infection.
What are normal IgG levels?
Normal Ranges Adult: IgG 6.0 – 16.0g/L. IgA 0.8 – 3.0g/L.
What IgG levels mean?
An IgG deficiency is a health problem in which your body doesn’t make enough immunoglobulin G (IgG). Normally, IgG is the most abundant antibody in the blood. It helps prevent infections. So, people with IgG deficiency are more likely to get infections.
What does HSV-2 0.90 mean?
0.90-1.09 IV: Equivocal – Questionable presence of IgG antibodies. Repeat testing in 10-14 days may be helpful. 1.10 IV or greater: Positive – IgG antibody to HSV detected which may indicate a current or past HSV infection.
What is high IgG levels?
High levels of IgG can mean you have an autoimmune disorder. An autoimmune disorder causes your immune system to attack healthy cells, tissues, and/or organs by mistake. These disorders can cause serious health problems.
What does a very high HSV-1 IgG mean?
What should your IgG level be?
Normal Ranges Adult: IgG 6.0 – 16.0g/L. IgA 0.8 – 3.0g/L. IgM 0.4 – 2.5g/L.
What does 0.91 mean on HSV test?
Test results for herpes fall within a numeric range. If your test returns a value of 0.91 or below you are negative. A value of 1.09 or above is a positive.
How to test for herpes?
For each available herpes test, we will mention: The swab test may be performed as soon as the first blisters appear (the sample to be tested must be collected from a herpes lesion). Technique: A doctor scrapes the fresh lesion (s), collecting skin and fluid.
Why does the IgG number fluctuate on the herpeselect test?
When the HerpeSelect test is performed, in addition to a positive test results it gives an IgG number that fluctuates. We will explain here why that happens and the practical significance of it. Let’s start with the basics: What is IgG? We produce different antibodies in response to infection.
How is a swab test performed for herpes?
The swab test may be performed as soon as the first blisters appear (the sample to be tested must be collected from a herpes lesion). Technique: A doctor scrapes the fresh lesion (s), collecting skin and fluid.
Can IgM reappear in a blood test after a herpes outbreak?
Many assume that if a test discovers IgM, they have recently acquired herpes. However, research shows that IgM can reappear in blood tests in up to a third of people during recurrences, while it will be negative in up to half of persons who recently acquired herpes but have culture-document first episodes.
