Cut off levels are the minimum concentrations of a substance that a point of care rapid toxicology test can detect. These levels are important because they determine whether a test result is positive or negative. If the concentration of a substance is below the cut off level, the test result will be negative, even if the substance is present in the sample. It is important to understand these levels to properly interpret test results and make informed decisions regarding patient care. In addition, cut off levels can vary depending on the type of test and the substance being tested, so it is important to have a thorough understanding of the specific test being used.
