Does equivocal mean positive HSV 1?
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.
Is an equivocal result positive?
What does an equivocal result mean? “Equivocal” means results cannot be interpreted as positive or negative because they are below the limit of detection (see below). Reasons may be: Very early or late in infection.
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.
Does HSV IgM go away?
IgM antibodies against HSV usually begin to form within 1-2 weeks after onset of the infection. The IgM antibody response usually declines rapidly such that after a few weeks or months (depending on the infection) they are undetectable.
Can equivocal be negative HSV?
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. 3.
When does HSV IgM become positive?
The time required for the development of IgG antibodies following HSV infection varies from 21 to over 42 days with most individuals having detectable IgG 21–28 days after exposure to the infection and probably lasting for life.7–,9 IgM antibodies are usually detectable 9–10 days after exposure and last 7–14 days.
What does equivocal STD test result mean?
An equivocal result interpretation indicates that the analyte being detected in the test system falls within the range between negative and positive.
What does an equivocal titer result mean?
A positive titer result indicates that you have immunity to that disease. A negative result shows you do not have immunity to that disease. Equivocal means that you are borderline.
What is a positive HSV-1 result?
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 causes equivocal result?
Equivocal antibody test results mean that the results could not be interpreted as positive or negative. Reasons for this may include: There is an immune response but it’s not strong enough to give a positive result. You may have had an infection in the past caused by another virus in the coronavirus family.
What does an equivocal Covid 19 antibody test result mean?
If your antibody test is equivocal, it means that the result is inconclusive. A repeat blood test 2 or more weeks after your first test may give a positive or negative result.
What does equivocal mean on HSV test?
Herpes IgM test results: 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 you test positive for HSV-1 and not have it?
Also, false positive test results (test results that say you have herpes when you do not actually have the virus) are possible. Even if you do not have symptoms, you should talk openly and honestly about your sexual history with your doctor to find out if you should be tested for any STDs, including herpes.
Are HSV IgM tests accurate?
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.
Does IgM test detect HSV-1 and HSV2?
– The IgM blood test cannot accurately distinguish between HSV-1 and HSV-2 antibodies and in many cases can provide a false-positive result for HSV-2 virus. In addition, the test can also connect with other viruses like the varicella-zoster virus or cytomegalovirus and provide misleading results.
What do IgG levels tell us about herpes simplex?
Support the diagnosis of Herpes simplex infection (type 1 or type 2). The presence of IgG antibody generally indicates past exposure and immunity. The presence of IgM antibody indicates recent infection. Single IgG levels are not useful for supporting the diagnosis of an acute infection.
Which antibody findings are characteristic of herpes simplex (HS) infection?
Support the diagnosis of Herpes simplex infection (type 1 or type 2). The presence of IgG antibody generally indicates past exposure and immunity. The presence of IgM antibody indicates recent infection.
How do you test for herpes simplex virus type 1?
Centrifuge, aliquot serum into a plastic vial and refrigerate. Test includes Herpes simplex IgG Type 1 (HSV1) and Herpes simplex IgG Type 2 (HSV2). Note that the Type 1 and Type 2 assays may also be ordered individually.
