10 General Chemistry in the Workplace Laboratory Testing Validity Testing Initial Screening (Immunoassay). –Negatives >>> negative (>95%). –Non-negative >>> confirmation process. Confirmation process. –Gas Chromatography –Mass Spectroscopy
11
11 General Chemistry in the Workplace Validity Testing pH –Normal 4.0 – 9.0. Specific Gravity (density relative to water) –Normal 1.003 – 1.030. Creatinine –>20 mg/dl.
12
12 General Chemistry in the Workplace Oxidizing & Adulterant Agents PCC (pyridinium chlorochromate) –UrineLuck (hexa-valent) –Chromax (chromium picolinate – tri-valent) OK. Glutaraldehyde –UrineAid, Clear Choice
13
13 General Chemistry in the Workplace Oxidizing & Adulterant Agents Nitrites (NO2 - ) –Klear, Whizzies –Poppers, Huffers (alkyl nitrites, butyl nitrite) Peroxide –Stealth –Peroxidase and H2O2.
14
14 General Chemistry in the Workplace Initial Screening - Immunoassay Immunoassay – A biochemical test that measures the presence or concentration of a substance in complex mixture of substances.
15
15 General Chemistry in the Workplace Immunoassay – Initial Screening Antibody – Proteins in your body’s immune system that are used to identify and neutralize foreign objects. Antigen – A molecule that binds to an antibody. Basic Idea – Use the body’s immune system to find & identify analytes. Two Volunteers, please.
