The biological terrain assessment or BTA is a set of tests used to measure the pH, resistivity, and redox of a person's urine, blood, and saliva.[1][2] The measurements were first used by L.C. Vincent, a French hydrologist, in the early 1900s.[3] It is often associated with homeopathy and holistic health. The usefulness of the test is debatable and according to physician Stephen Barrett BTA is outdated, apart from pH measurement, and is an inferior assessment technique that should not be favored over more modern techniques.[1]
