Most likely it does. You should try to keep it that way. However, there’s a small percentage of cases (about 5–9%) where the results aren’t clear enough. Moreover, in older people, toxoplasma antibody levels may be so low as to cause false‑negative results. Sometimes, a repeated blood taking and a new test may help, but more often the results remain unclear even after that. The interpretation of results should always be handled by specialists, such as those from the National Reference Laboratory for Toxoplasmosis of the National Institute of Public Health in Prague.
