How accurate is the blood test for herpes?
The accuracy of any blood test for herpes depends on many factors. Some types of testing are more efficient than others and the time between virus contraction and testing can play a major role in whether the results are accurate. False positives and false negatives are quite common, mainly because of the fact that some tests do not check herpes specific to the type. In addition, some antibody tests may accidentally antibodies produced in response to other viruses for those who produce red in response, herpes. There are two common types of herpes, and these are the most tested. Herpes Simplex Virus 1 (HSV-1) is a species that causes oral symptoms such as ulcers. Herpes Simplex Virus 2 (HSV-2) is commonly known as genital herpes because it is mostly sexually transmitted and leads to blisters on and around GE and around genitals. In order to achieve the most accurate results, patients should apply for a doctor to perform a type test for herpes genital aspects because about half of the population is infected with HSV-1 and interrogationDky could show false positive.
Overall, there are two main types of blood tests for herpes. The ELISA test is about 92% effective for both positive and negative results for HSV-1 and 97% effective for HSV-2. The immunoblot test is about 99% effective for HSV-1 testing and 98% effective for HSV-2. The results will vary depending on how soon after the transmission the person is tested because the body takes time to produce antibodies in sufficiently high levels to detect in the blood.
It is generally not recommended for patients to receive a routine blood test for herpes if they believe they will be at risk of closing the virus. The reason is that false positive can cause disproportionate stress on those who actually do not have herpes. However, if it was sexually active without proper protection, the test may be necessary, as herpes may be transmitted before the presence of symptoms.
youJně accurate as a blood test for herpes can be, the most accurate way to be diagnosed, involves testing symptomatic patients by the fact that the blisters that form around the genitalia or mouth. This can provide a definitive diagnosis, even if it is necessary to wait for the first outbreak of symptoms before testing. Usually, those who are at high risk of herpes may initially undergo a blood test and subsequent testing would become symptoms after the negative first result.
