Listed below are the chemicals most commonly tested for in a urine analysis.

Alcohol

While Alcohol is not part of the standard drug test, it is not uncommon to test for in some situations. It is less common in pre-employment tests, but is relatively common for parole testing or random on the job testing, especially for safety sensitive jobs.

Amphetamine

Amphetamines generally cause strong physical and mental stimulation, keeping users awake and alert for many hours, and some amphetamines cause mood lift / euphoria. There is however, a surprisingly long list of over the counter substances that can trigger FALSE POSITIVES for Amphetamines. These substances include: Ephedrine, pseudoephedrine, propylephedrine, phenylephrine, or desoxyephedrine ( Nyquil, Contact, Sudafed, Allerest, Tavist-D, Dimetapp, etc ) Phenegan-D, Robitussin Cold and Flu, Vicks Nyquil Over-the-counter diet aids with phenylpropanolamine (Dexatrim, Accutrim)

Over-the-counter nasal sprays ( Vicks inhaler, Afrin )Asthma medications (Marax, Bronkaid tablets, Primatine Tablets) Prescription medications (Adderall, Amfepramone, Cathne, Etafediabe, Morazone,...phendimetrazine, phenmetrazine, benzphetamine, fenfluramine, dexfenfluramine, ...dexdenfluramine,Redux, mephentermine, Mesocarb, methoxyphenamine, phentermine,... amineptine, Pholedrine, hydroymethamphetamine, Dexedrine, amifepramone, clobenzorex,...fenproyorex, mefenorex, fenelylline, Didrex, dextroamphetamine, methphenidate, Ritalin, ...pemoline, Cylert, selegiline, Deprenyl, Eldepryl, Famprofazone)

Barbiturates

Detection periods for barbiturates vary greatly depending on the specific barbiturate being used. Each barbiturate has a different half-life in the body, meaning they stay around for different periods of time. Medications that would trigger a false positive would be: Dilantin, Fiorinal, and Fioricet. Fiorinal and derivatives are often prescribed for migraines and chronic tension headaches.

Benzodiazepines

Benzylpiperazine (BZP) is a piperazine and a CNS stimulant. It is one of the more commonly used piperazines, providing stimulant effects which people describe as a noticeably different than those of amphetamines. In fact, laboratories screen for BOTH of these chemicals.

Cannabinoids(THC)

THC is one of the "NIDA 5", ( One of the five drugs tested for in the standard NIDA approved drug test.) It is detectable in Urine for 48-72 hours after single use. Habitual or chronic use can be detected in urine sometimes more than 12 weeks depending on quantity, duration, and frequency of use.

Cocaine

Cocaine is also one of the 'NIDA-5' tested for in drug tests. It can be detected for approximately 48-72 hours after single use. Frequent or heavy use can be detected much longer. Cocaine is metabolized in the liver and is then excreted though urine as benzoylecgonine and ecgonine methyl ester.

Opiates

Heroin breaks down into codeine and morphine. Codeine breaks down into morphine. The opiate drug tests look for codeine, morphine, and 6-acetyl-morphine. Opiates are excreted through the urine while their metabolites remain unchanged.

Phencyclidine

10% of PCP is excreted unchanged in the urine. The remainder is metabolized into hydroxylate or glucuronide. Standard urine screening and gc/ms test for both PCP and its metabolites. PCP is stored by the body in fatty lipid tissue for up to several weeks. Chronic users and individuals with high body fat count are at the greatest risk of long-term detection.
