[|AI|]  Hello, A single test cannot in itself give a diagnosis, except when done in an endemic area. In the early weeks, tests can be false negative. A rise in title of four-fold in a repeat test after 7 days is conclusive evidence of the presence of the disease. In a single test, the result is considered to be positive if the titles are seen in 1:160 dilution. As such, your test report is inconclusive. You may repeat the test after consulting your physician. Wish you good health.
