In medicine, baseline testing refers to any test that measures a patient’s current or pre-treatment condition. In a clinical study, a baseline test would be conducted at the beginning of the study. Baseline testing results are used as a reference point for comparison to subsequent test results.

This panel contains the following components: Amphetamine, Barbiturates, Benzodiazepines, Cocaine, Methadone, Methamphetamine, Opiates, Oxycodone, Phencyclidine, Propoxyphene, Cannabinoids (THC), and Tricyclic Antidepressants or their metabolites.

Standard 10-panel test: typically looks for cocaine, marijuana, PCP, amphetamines, opiates, benzodiazepines, barbiturates, methadone, propoxyphene, & Quaaludes. 12-panel test: often administered as an extension to the 10-panel test.

The sample adequacy window turns blue when the oral fluid sample quantity is sufficient for testing, thereby taking the guesswork out of collecting oral fluid specimens and reducing repeat drug test collections.

A colored band must be visible in each control region (C) to indicate that the test is valid. If a colored band is visible in any of the Test Regions (T), it indicates that concentration of the drug in the corresponding test zone is absent or below the detection limit of the test.

The anti-inflammatory drug sulfasalazine (Azulfidine),phenazopyridine, some laxatives and certain chemotherapy drugs might cause your urine color to be orange. The antidepressant amitriptyline, the pain reliever indomethacin (Indocin, Tivorbex) and the anesthetic propofol (Diprivan) may turn your urine blue or green.

Leukocyte esterase is a screening test used to detect a substance that suggests there are white blood cells in the urine. This may mean you have a urinary tract infection. If this test is positive, the urine should be examined under a microscope for white blood cells and other signs that point to an infection.

A dipstick — a thin, plastic stick with strips of chemicals on it — is placed in the urine to detect abnormalities. The chemical strips change color if certain substances are present or if their levels are above normal. A dipstick test checks for: Acidity (pH).

Guidance from PHE [PHE, 2017] states that if dipstick is positive for nitrite or leukocyte and red blood cells (RBC) UTI is likely; if urine dipstick is negative for nitrite and positive for leukocyte, UTI is equally likely to other diagnoses; and if urine dipstick is negative for all nitrite, leukocyte and RBC UTI …

Some of the most common agents that are added to a urine sample include bleach, eyedrops, hand soap, vinegar, table salt, and lemon juice. These chemicals can be easily concealed in small vials and are usually added to the sample when individuals are taking the test unsupervised.

Leukocytes in the urine without nitrite If the test for leukocyte esterase is positive but finds no nitrite, an infection may still be present. The test is particular to certain bacterial enzymes, which means it can pick up specific bacterial infections with more certainty.

Treatment for leukocytes in the urine depends on the cause and if there is an infection. For some conditions, such as a bacterial UTI, antibiotic therapy will clear up the infection relatively quickly. For more severe infections or those that will not resolve easily, more in-depth medical treatment may be needed.

If your doctor tests your urine and finds too many leukocytes, it could be a sign of infection. Leukocytes are white blood cells that help your body fight germs. When you have more of these than usual in your urine, it’s often a sign of a problem somewhere in your urinary tract.
