Urine Specimens 101 – While it is the most common drug testing method, Urine testing is not foolproof. Common Alterations of Urine include Adulterated specimen, Diluted specimen, Substituted specimens. Often not detectable by POC cups

UDT+ Includes Specimen Validity Testing. With specimen validity testing, we can help ensure the integrity of the test by measuring pH, creatinine and specific gravity.

Pros vs. Cons

POCT testing cup

Disadvantages of POCT testing include:

Less accurate and reliable compared to laboratory analysis.

POCT often reports false positives especially if the employee is taking legal medications that fall into the same class of substance as illegal drugs.
Chances of false positive=5% Chances of false negative = 40% *

POCT is unable to distinguish between individual compounds, and therefore only reports the class of drug. In other words, a POCT can test for the metabolites of opiates but not tell if it is specifically heroin.

The sensitivity of the POCT device varies based on manufacturer, target compound and the threshold set for detection. (High Cutoffs)

Typically, doesn’t test for specimen validity and sample adulteration

Lab Based Testing equipment

Advantages of Lab Based Testing:

It is more reliable and accurate compared to on-site POCT. Immunoassay technology has an accuracy rate of over 99 percent

The reagents used are more Specific and Sensitive to the drug classes

Specimen Validity Testing can detect whether or not a urine specimen has been tampered with prior to testing

Lab performs Daily QC checks, Weekly Calibrations, and Ongoing Proficiency testing programs. This greatly reduces the chance of false test results.

Lab staff have higher levels of expertise/training in the conduction and interpretation of tests.

The results can be stored for future medical or legal access.

Definitions

Adulterated specimen: A urine specimen containing a substance that is not a normal constituent or containing an endogenous substance at a concentration that is not a normal physiological concentration.
Diluted specimen: A urine specimen with creatinine and specific gravity values that are lower than expected for human urine. 2017-00979.pdf (govinfo.gov)

Substituted specimen: A urine specimen with creatinine and specific gravity values that are so diminished or so divergent that they are not consistent with normal human urine. 07-4428.pdf (govinfo.gov)
Creatinine is endogenously produced and cleared from the body by the kidneys. It is a normal constituent in urine. Normal human urine creatinine concentrations are at or above 20 mg/dL.

pH is the measurement of acid-base. Human urine is usually near neutral (pH 7), although some biomedical conditions affect urine pH. HHS set the program cutoffs for pH based on a physiological range of approximately 4.5 to 9

Specific Gravity is a measure of the density of a substance compared to the density of water. For urine, the specific gravity is a measure of the concentration of dissolved particles in the urine. Normal values for the specific gravity of human urine range from approximately 1.001 to approximately 1.020.
