Diagnosis of herpes meclizine hcl 25 mg antiemetic

• Type-specific herpes blood tests look for not only whether you have antibodies against a herpes virus, but also for whether the antibodies are against HSV-1 or HSV-2. Type-specific testing will not tell you where your herpes infection is located in your body since the oral herpes virus can infect the genitals and vice versa.

HerpeSelect ELISA – 21 days for people who were HSV-1 negative and 23 days for people who were HSV-1 positive Western Blot – 40 days for people who were HSV-1 negative and 47 days for those who were HSV-1 positive Western Blot – 68 days Kalon ELISA – 120 days Focus ELISA – 21 days

It usually takes around two weeks for symptoms to appear after you have been infected with HSV type 1 or 2. It is a good idea to wait at least a month or two before getting an HSV-2 test after a potential exposure.

If you have a strong reason to believe that you have been infected, you might want to consider getting retested after six months because some of the tests take longer to become positive.

There is some possibility that herpes blood tests may detect antibodies to similar viruses through cross-reaction. This result would be a false positive, which is a test result that suggests that you have an infection when you don’t. The risk of getting such a false positive is related to the specificity of the particular herpes blood test being used and also to the prevalence of herpes in the population getting tested.

Because it takes time for your body to produce antibodies after you have been infected, this may lead to false negatives. False negative results occur when test results suggest that you do not have an infection when you actually have the infection. False negatives may occur if you have the test before you have produced antibodies.

The diagnosis of herpes in newborns is challenging. Generally, babies are not screened for herpes infection. Symptoms, such as lesions around the mouth or eye, may alert caregivers that there is a problem. This should prompt diagnostic testing, which can be done using a swab sample. However, more complicated neonatal herpes infections, such as encephalitis (infection of the brain), require more specific tests such as a lumbar puncture. Differential Diagnosis

• Canker sores: Canker sores are usually red, raised sores with a painful, raw whitish pit in the center. They may be present in the mouth, and they tend to occur as a result of trauma in the mouth. The initial painful sensation of canker sores and cold sores is similar, but the lesions look different, and canker sores do not test positive for herpes simplex virus.

• Syphilis: A sexually transmitted disease that produces painless genital sores, syphilis can be confused with herpes. Your doctor may be able to tell the difference by visually inspecting the lesions. If you have syphilis, your blood tests should be positive for Treponema pallidum, the bacteria that causes syphilis infection, while they would be positive for HSV if herpes is the cause of your genital lesions.

• Cancer/ pre-cancer: Lesions in and around the genital area can be signs of cancer. The appearance of cancerous or pre-cancerous lesions should not have the blisters that often are present with HSV induced lesions. But if your doctor needs to distinguish between cancer and herpes, a swab or a needle biopsy (sample of the lesion), can differentiate the two conditions by inspection under a microscope.
