Read the SVT results in two to five (2-5) minutes after receipt of specimen. Do not read after five (5) minutes. Compare color development on each pad to the corresponding test on the color chart included.

pH: Tests for the presence of acidic and alkaline adulterants. Normal urine pH ranges from 4.0 to 9.0 Values below pH 4.0 or above pH 9.0 are indicative of adulteration.

Specific Gravity: Tests for specimen dilution. Normal levels range from 1.003-1.030.

Oxidants: Tests for the presence of oxidants such as bleach, nitrites, peroxide, and chromates. A blue or green color will form on the oxidant pad when oxidants are present in the specimen.

Note: the SVT should not be interpreted by persons that are color blind.
