Specimen validity test.
This is a simple test to establish the integrity of human urine with seven different checks.
- Creatinine: Tests for a waste product called creatine which is present in human urine.
- Glutaraldehyde: Tests for the presence of exogenous aldehyde.
- Nitrites: Tests for commonly used commercial adulterants.
- Oxidants: Tests for the presence of oxidants.
- pH: Tests for the presence of acidic and alkaline adulterants.
- BL: Tests for bleaching products.
- Specific Gravity: Tests for sample dilution.
Available in single test strips or packs of 25.
Without a preliminary specimen validity test you can never be sure if the urine has been tampered or modified. The drug test will be compromised and overt the true result of the test.
We recommend that every drug test be supported with a specimen validity test.
The HHS recommend that a specimen validity test for pH and specific gravity be used for initial and confirmatory tests.
Note: The use of adulterants can cause false negative results either by interfering with the screening test and or by destroying the presence of drugs in urine. Dilution may also be employed in an attempt to produce a false negative result. Dilution of urine with water is probably the simplest urine adulteration method. Bleach, vinegar, Visine, sodium bicarbonate, sodium nitrite, Drano, soft drinks and hydrogen peroxide are examples of adulterants that can compromise a drug test.
