Drug detection test kit DBZ-12

ascorbic acidspecific gravitycotinine

Product overview
The Urinalysis Reagent Strips (Urine) are firm plastic strips onto which several separate reagent areas are affixed. The test is for the qualitative and semi-quantitative detection of one or more of the following analytes in urine: Ascorbic acid, Glucose, Bilirubin, Ketone (Acetoacetic acid), Specific Gravity, Blood, pH, Protein, Urobilinogen, Nitrite and Leukocytes.

Explain / Principle
The Rapid Response Drugs of Abuse Test Device detects drugs of abuse through visual interpretation of color development on the internal strip. Drug conjugates are immobilized on the test region of the membrane. During testing, the specimen reacts with antibodies conjugated to colored particles precoated on the sample pad. The mixture migrates through the membrane by capillary action and interacts with reagents on the membrane. If drug molecules are below cutoff, the antibody-colored particle conjugate binds to immobilized drug conjugates forming a colored band at the test region (negative). If drug molecules exceed the cutoff, they compete for antibody binding sites preventing formation of the colored band in the test region (positive). A colored band at the control region indicates proper specimen volume and membrane wicking.

pH | 60 seconds | Methyl red sodium salt; bromthymol blue; non-reactive ingredients | Permits quantitative differentiation of pH values within the range of 5-9.

Urobilinogen (URO) | 60 seconds | p-diethylaminobenzaldehyde; buffer and non-reactive ingredients | Detects urobilinogen as low as 0.2-1.0 mg/dL (3.5-17 μmol/L).
Nitrite (NIT) | 60 seconds | p-arsanilic acid; N-(1-naphthyl)ethylenediamine; non-reactive ingredients | Detects sodium nitrite as low as 0.05-0.1 mg/dL in urine with low SG and <30 mg/dL ascorbic acid.
Leukocytes (LEU) | 120 seconds | Derivatized pyrrole amino acid ester; diazonium salt; buffer; non-reactive ingredients | Detects leukocytes as low as 9-15 white blood cells Leu/µL in clinical urine.

Adulteration Test Strips (Specimen Validity Tests)
Drug adulteration test strips identify whether a urine sample has been intentionally manipulated, contaminated or diluted. The six-in-one Adulteration Test Strips detect:

• Creatinine – checks for dilution; absence (<5 mg/dL) indicates specimen not consistent with human urine.
• Specific Gravity – checks sample dilution; normal human urine 1.003–1.030.
• Nitrite – detects common commercial adulterants that oxidize metabolites; normal urine contains no nitrite.
• Glutaraldehyde – identifies adulterants that disrupt immunoassay enzymes; not normally found in urine.
• pH – normal pH range 4.0–9.0; values outside may indicate tampering.
• Oxidants/PCC – detects oxidizing agents (bleach, hydrogen peroxide, pyridinium chlorochromate) used as adulterants.
