How do you interpret HSV IgG results?
How do you interpret HSV IgG 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 is the size of HSV-1?
Electron microscopy (EM) and electron tomography (ET) studies of HSV-1 have revealed that virus particles have a spherical shape4, with diameter ranging from 155 to 240 nm, each containing an icosahedral capsid with a diameter of 125 nm5,6, which contains the viral DNA.
What is the difference between HSV-1 IgG and HSV-2 IgG?
Most commonly, herpes type 1 causes sores around the mouth and lips (sometimes called fever blisters or cold sores). HSV-1 can cause genital herpes, but most cases of genital herpes are caused by herpes type 2. In HSV-2, the infected person may have sores around the genitals or rectum.
What does it mean if HSV-1 IgG is high?
A positive result means that the patient has an HSV infection. The patient may be experiencing an initial outbreak or a recurrent outbreak from a past infection.
What is considered positive for HSV-2?
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.
Can HSV antibodies go away?
It may take between six and eight weeks to detect antibodies in a herpes blood test after first becoming infected with HSV. Also, antibodies may disappear with time, especially if the person has infrequent recurrences of herpes.
What is a high range for 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.
What does positive HSV IgG mean?
Your body produces IgM and IgG antibodies after HSV infection. The IgM test can detect HSV earlier than the IgG test. A positive IgM test might mean you have a new or recurrent HSV infection. If you have a positive IgM test and a negative IgG test, you likely have a new infection.
