Specimen validity test.

This is a simple test that will establish the integrity of human urine by testing for seven different adulterants.

  1. Creatinine: Tests for a waste product called creatine which is present in human urine.
  2. Glutaraldehyde: Tests for the presence of exogenous aldehyde.
  3. Nitrites: Tests for commonly used commercial adulterants.
  4. Oxidants: Tests for the presence of oxidants.
  5. pH: Tests for the presence of acidic and alkaline adulterants.
  6. BL: Tests for bleaching products.
  7. Specific Gravity: Tests for sample dilution.

Available in single test strips or packs of 25.

Urine drug tests will only work correctly if the urine sample is within normal parameters, as this is how they were to designed work.
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.

This is an example of the color comparison chart included in the 25 pack kit.

Instructions

Procedure.

1. Remove from the bottle only enough strips for immediate use and replace cap tightly.

2. Completely immerse reagent areas of the strip in fresh, well-mixed urine. Remove the strip immediately to avoid dissolving out the reagent areas.

3. While removing, touch the side of the strip against the rim of the urine container to remove excess urine. Blot the lengthwise edge of the strip on an absorbent paper towel to further remove excess urine and avoid running over contamination from adjacent reagent pads.

4. Compare each reagent area to its corresponding color blocks on the color chart and read at the times specified. Proper read time is critical for optimal results.

5. Obtain results by direct color chart comparison.


Interpreting the results

In general, all seven tests are based on the chemical reactions of reagents on the pads with components in the urine sample effecting a color changes. Results are obtained by comparing the color on each of the test pads with the corresponding pad on the container color chart label.

  • Creatinine: Testing, for sample dilution. In this assay, creatinine reacts with a creatinine indicator in an alkaline condition to form a purplish-brown color complex. The concentration of creatinine is directly proportional to the color intensity of the test pad.
  • Glutaraldehyde: Testing for the presence of exogenous aldehyde. In this assay, the aldehyde group on the glutaraldehyde reacts with an indicator to form a pink/purple color complex.
  • Nitrite: Testing for the presence of exogenous nitrite. Nitrite reacts with an aromatic amine to form a diazonium compound in an acid medium. The diazonium compound in turn couples with an indicator to produce a pink-red/purple color.
  • Oxidants: Testing for presence of oxidizing reagents. In this reaction, a color indicator reacts with oxidants such as hydrogen peroxide, ferricyanide, persulfate, or pyridinium chlorochromate to form a blue color complex. Other colors may indicate the presence of other oxidants.
  • pH: Testing for the presence of acidic or alkaline adulterant. This test is based on the well-known double pH indicator method that gives distinguishable colors over wide pH range.
    The colors- range from orange (low pH) to yellow and green to blue (high pH).
  • Specific Gravity: Testing for sample dilution. This test is based on the apparent pKa change of certain pretreated poly electrolytes in relation to the ionic concentration. In the presence of an indicator, the colors range from dark blue or blue-green in urine of low ionic concentration to green and yellow in urine of higher ionic concentration.
  • Bleach: Testing for the presence of bleach in urine. In this test, the presence of bleach forms a blue-green color complex.
  • Pyridium Chlorochromate: Testing for the presence of chromate in urine. In this test, the presence of chromate forms a blue-green color complex.
