What causes a false positive result on herpes test?
False-Positives are more commonly associated with IgM testing, not IgG
Hello ma'am and welcome.
Thank you for writing to us.
I have gone through your query with diligence and would like you to know that I am here to help. There are a couple of facts I would like to state for your better understanding on the test and its results, they are:
+The major problem with HSV testing are the false-negative results. This is because due to certain factors the test result can provide a negative result, despite the individual actually having HSV. This also means that when a positive result is seen, it is almost always because the virus is present
+IgM testing does provide a false-positive result at times, and thus is considered less accurate than IgG testing. But as mentioned by you, you underwent IgG testing, and this is almost always accurate
+IgG testing is time consuming, mainly because it takes time for an individual to produce detectable levels of IgG antibodies. This also means that once a positive result is seen, it always indicates the presence of the virus
I am sorry to be informing you this, but these are facts ma'am. Do not worry, as your doctor will most certainly help you to deal and cope with the virus, and you can continue living life in a healthy manner. Many individuals, in fact around 20 % or more individuals with HSV are asymptomatic just like you. But if you wish you can go for a retest.
I hope you find my response helpful. Please feel free to write back to me for any further clarifications, I am always here to help.
