Window of Detection

The window of detection refers to the time period during which a substance can be detected in a patient’s sample using point of care toxicology screening. Understanding the window of detection is important because it can vary depending on the substance being tested and the type of test being used. It is necessary to know the window of detection for a specific substance in order to interpret test results accurately and make informed decisions regarding patient care.
