Healgen Scientific 6 Parameter Adulteration Test Strips for Urine #HUAD-164

Tests for: Oxidants/Pyridinium (PCC), Specific Gravity, pH, Nitrite, Glutaraldehyde, and Creatinine

Urine reagent strips for Adulteration is a screening test device for the visual qualitative determination of creatinine, nitrite, glutaraldehyde, pH, specific gravity, and oxidents/pyridinium chlorochromate in urine, it does not indicate the level or concentrations of compounds present in the sample.
Results in one minute.

Healgen SVT Adulteration Test Strips #HUAD-164

The validity of DAU screening depends on the integrity of the urine samples. Contaminated or adulterated samples may cause erroneous results leading to
significant consequences. Hence, it is important to ensure that the samples are intact and consistent with normal human urine.

The urine adulteration test strips are plastic strips affixed with seven reagent pads. The pads are chemically treated with specific reagents to
provide visual comparison of these pads with the color chart on the container label after dipping the test strip into a urine sample, the following information
can be obtained which may be useful in assessing the integrity of the urine sample:

    • Whether the sample is diluted or substituted with water or other liquids as indicated by the creatinine and specific gravity tests.
    • Whether the sample contains commercially available adulterants including nitrite3 “KLEAR”, glutaraldehyde4, bleach, pyridinium chlorochromate “Insta Clean
      ADD-IT-IVE”, “LUCKY LAB”, and other oxidizing agents “STEALTH”, “Urine Luck”.
    • Whether the sample is contaminated with common household items, such vinegar, Drano, Hydrogen Peroxide and Bleach as indicated by the pH, Bleach and
      Pyridinium Chlorochromate tests.




Creatinine In this assay, creatinine reacts with a creatinine indicator in an alkaline medium to form a purplebrown color complex.
The color intensity of the test pad is directly proportional to the concentration of creatinine in the sample.

Daily creatinine excretion, related to muscle mass of the human body, is usually constant. Urine specimens with creatinine
levels of less than 20 mg/dl are indications of adulteration. This test covers the most common form of specimen tampering,
specimen dilution. Dilution using diuretics is also often referred to as “flushing”.
Glutaraldehyde This analysis is based on the reaction of the aldehyde group on the glutaraldehyde with an indicator to generate a brown color

Tests for the presence of exogenous aldehyde. Glutaraldehyde is not a natural component of human urine and it
should not be present in normal urine. Common occurrences are the additives of such products such as Clear Choice or UrinAid.
Nitrite This test is based on the reaction of aromatic amine to yield a diazonium salt, which then couples with an indicator to form a
color complex ranging from pink to dark red depending on the concentration of nitrite in the sample.

Tests for the presence of exogenous nitrate. Nitrate level above 7.5 mg/dl in human urine is considered abnormal. Common
occurrences are the additive of such products as Klear.
Pyridinium Chlorochromate In this assay, a color indicator reacts with pyridinium chlorochromate to form a blue, brown or black color complex.
Bleach In this reaction, a color indicator reacts with bleach to form a blue complex.
pH Level This test utilizes the principle of multiple indicators that give a broad range of colors ranging from orange (low pH)
to yellow and green (pH 4 to 9) and brown (high pH). Tests for the presence of acidic and alkaline adulterants. Normal urine
pH ranges from 4.0 to 9.0. Values below pH 4.0 or above pH 9.0 are indicative of adulteration.
Specific Gravity This test is based on the release of protons from a polyacid in the presence of cations in the test liquid. When the released protons
react with the indicator reagent, a colored reaction is produced. The color ranges from green to light green, olive green to red
depending on the specific gravity of the sample.

Tests for sample dilution. Normal levels for specific gravity will range from
1.003-1.030. Specific gravity levels of less than 1.003 or higher than 1.030 is an indication of adulteration.
