A small percentage of positive HSV-2 IgG results may be false-positive.1 Further testing may be appropriate for patients with a low or unexpected positive HSV-2 IgG result. The HSV-2 IgG Inhibition, ELISA performed at Focus Diagnostics Reference Laboratory can be used to further characterize the sample and distinguish a false-positive from a true-positive result.

Antinuclear Antibody Panel (ANA Test) However, other tests may still be needed based on your symptoms. Some people with autoimmune diseases may test negative for ANA but positive for other antibodies. A positive ANA test means that you have high levels of ANA in your blood. A positive ANA test is usually reported as both a ratio (called a titer) and a pattern, such as smooth or speckled. Certain diseases are more likely to have certain patterns. The higher the titer the more likely the result is a “true positive” result, meaning you have significant antinuclear antibodies and an autoimmune disease. However, a positive result doesn’t always mean that you have an autoimmune disease.
