Presumptive Positive: One colored line is visible in
the control (C) zone for that drug. No colored line whatsoever appears in the
test (T) zone, indicating a presumptive positive result for the corresponding
drug.
Negative: Colored lines are visible in both the
control (C) and test (T) zones, indicating that concentration of the drug is
below the detection limit of the test or not present.
Adulteration Tests
- Creatinine (CR)
- Glutaraldehyde (GL)
- Nitrite (NI)
- Oxidants/Bleach (OX)
- ph (PH)
- Specific Gravity (SG)
Adulteration (specimen validity) results are obtained by direct comparison of
the colored pads on reacted strips to color blocks on the Adulterant Color
Chart. Adulterated urine will show result colors similar to those in the
“Abnormal” columns of the color chart. Unadulterated samples will show strip
colors similar to those in the “Normal” column.
