How does Specimen Validity testing work?
One of the best ways to detect adulteration is to look for certain characteristics such as pH, Specific Gravity, Oxidants, color and Temperature, – pH test for acidic or Alkaline products in urine. Normal pH should be in the Range of 4.0 to 9.0. Values outside this range may indicate the sample has been spiked or altered – Oxidants/PCC (Pyridinium Chlorochromate): test for the presence of oxidizing agents such as bleach and hydrogen peroxide. Pyridinium Chlorochromate (sold under the brand name UrineLuck) is a commonly used adulterant. Normal human urine should not contain oxidants or PCC – Specific Gravity test for sample dilution. The normal range is between 1.003 and 1.030. Values outside this range should be considered adulterated. – Glutaraldehyde: test for the presence of an aldehyde. Adulterants such as UrinAcid and Clear Choice contain Glutaraldehyde which may cause false negative screening results by disrupting the enzyme used in some immunoassay test. Glutaraldehyde is not no
