What does 0.9 herpes mean?
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.

HSV 1 and 2-Spec Ab, IgG w/Rfx Negative <0.91 Equivocal 0.91 - 1.09 Positive >1.09 Note: Negative indicates no antibodies detected to HSV-1. Equivocal may suggest early infection. If clinically appropriate, retest at later date. Positive indicates antibodies detected to HSV-1.
What is negative numbers for herpes?
A negative (normal) test most often means you have not been infected with HSV-1 or HSV-2. If the infection occurred very recently (within a few weeks to 3 months), the test may be negative, but you may still be infected. This is called a false negative.

What is the normal range for herpes?
Optimal Result: 0 – 0.9 index.
What is a normal herpes test?
HSV testing is usually done as a swab test, blood test, or lumbar puncture. The type of test you get will depend on your symptoms and health history. For a swab test, a health care provider will use a swab to collect fluid and cells from a herpes sore.
What is a low positive for herpes?
An index value above 1.1 is considered positive, but some experts regard values less than 3.5 as “low positive” and recommend a confirmatory test such as the HSV Western Blot, long considered the gold standard with regards to accuracy and consistency of results.
How do you read herpes results?
A positive result indicates that HSV antibodies were detected and you had an active outbreak or past infection. Negative results from antibody testing indicate that HSV antibodies weren’t detected in the sample. This result could occur because you don’t have an active outbreak or past infection.
What percentage is positive for herpes?
More than 50% of adults in the U.S. will test positive for HSV-1. Most HSV-1 infections are oral and plenty of people don’t recall ever having a cold sore or symptoms that would explain their HSV-1 diagnosis.
What does 0.91 HSV test mean?
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. See additional test results and what they mean at our STD Test Results Sample page.
Does equivocal mean positive HSV-1?
A positive test result means that herpes IgM was detected in the sample. A negative result means that no IgM was detected. An equivocal test result means that the test was unable to determine whether or not there was an antibody present.
Can an HSV IgG test be wrong?
These tests have limits. For example, if a person gets a blood test too soon after an infection, the result could be wrong. A wrong result is also possible when the person has a low risk of infection.
What are the numbers of herpes?
Overview. Herpes infections are very common. Fifty to 80 percent of American adults have oral herpes (HSV-1), which causes cold sores or fever blisters in or around the mouth. Genital herpes, caused by HSV-1 or HSV-2, affects one out of every six people in the U.S. age 14 to 49.
Can you have herpes antibodies and not have herpes?
It is possible to have a false-positive result for herpes antibodies. This means that a person gets a positive result when they do not have the virus.
How accurate is a herpes blood test?
Herpes blood tests have a sensitivity level of about 80-98%. This type of test detects antibodies to the herpes virus, so it may not be as accurate when performed soon after infection.
How is herpes measured?
Standard viral culture: Tube culture isolation is the traditional gold standard for HSV detection and the reference method against which all other tests are measured (16,17). While the test has 100% specificity for HSV-1 or HSV-2, the sensitivity depends on the stage of the lesion at the time of specimen collection.
Can you tell how long you had herpes?
Unfortunately, most people who are diagnosed will not be able to determine how long they have had the infection. In addition, IgM tests cannot accurately distinguish between HSV-1 and HSV-2 antibodies, and thus very easily provide a false positive result for HSV-2.
How often are herpes tests wrong?
A test that is 90% sensitive will correctly identify 90 people out of 100 who have the disease. Ten people will have a false-negative result.
Does equivocal mean positive?
Equivocal: Your test results could not be interpreted as Positive or Negative. The most common reasons for equivocal results are presence of an immune response but unclear if against the infection being tested for (COVID-19 in this case) or similar infections (the common cold is a type of coronavirus).
Can equivocal HSV-2 be negative?
If the second specimen is also equivocal, the patient is negative for primary or recent infection, and equivocal for antibody status. If the second sample is positive, the patient can be considered to have previous experience with HSV-2 infection.
