Urine
Adulteration Drug Test Strip is a fast dip-and-read test for the determination
of diluted or adulterated urine specimens ( how drug test clean ). It
is an important pre-screening test for any drug-testing program. The
Urine Adulteration Drug Test Strip is a one-step chromatographic immunoassay
for the qualitative determination of changes how drug test clean in
Creatinine, Nitrite, Glutaraldehyde, pH, Specific Gravity and Oxidantes
in urine. You could check how visible are your cleansing process.
TEST PRINCIPLE
In
general, all six tests are based on the chemical reactions of the indicator
reagents on the pads with components in the urine sample effecting color
changes. Results are obtained by comparing the color on each of the
test pads with the corresponding pad on the color chart.
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 exogeniuos aldehyde. In this assay the aldehyde
group on the glutaraldehyde reacts with an indicator to produce a pink-red
color.
Oxidants:
Testing for presence of oxidizing reagents. In this reaction, a color
indicator reacts with oxidants such as bleach, hydrogen peroxide or
pyridinium chlorochromate to form a blue color comples. Other color
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 polyelectrolytes 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.
