There are many good tests available to determine whether you have Candida.
Testing for Candida albicans antibodies has drawbacks, as the sensitivity, or accuracy, of tests varies from person to person and test to test. False positives may result from various influences, past or present. If blood tests are done prior to the immune system developing a response to Candida infections, then there may be a false-negative test result. If the immune system is suppressed or fatigued from a longstanding infection, then a false-negative test result may also be present. If the immune system has been sensitized, but the infection is no longer present, it may produce a false-positive. While all tests can be useful, it is hard to determine the accuracy from any one test.
The “Candida Spit Test” is not a valid test for Candida as it may indicate the presence of: yeast, mold, fungus, allergies, bacteria, viruses, cold weather, changes in weather, or dehydration.
