How Long Can Lortab Be Detected in Your Urine?

Lortab is not detectable in urine after four days, as the kidneys continually flush toxins from the body. The body passes an average of 1 to 2 liters of urine daily, and the kidneys filter all substances, including Lortab, that pass though the urinary tract, according to Warde Medical Laboratory.

Lortab remains in urine longer than it does in saliva or blood serum, making urine drug screening the prefered test when checking for drug abuse or medication compliance, according to Warde Medical Laboratory.

Multiple substances are tested for in a drug urine screen, such as opioids and benzodiazepines, and urine drug tests are sensitive enough to detect the presence of a single drug such as Lortab, reports Warde Medical Laboratory.
