Drug Testing Is Hazardous To Your Work

The results of drug tests may be valid in some cases. These disadvantages of drug testing can reduce their freedom and lose your job.

Validity

The Center for Disease Control has tested the laboratories sending known amounts of drugs. The labs were unable to detect drugs present in the sample. Although the labs have improved the methodology and reliability, yet the problem continues.

The two donuts

Urine sample tested positive for opiates by RIA, EMIT. GC / MS identified morphine content. The individual denies the abuse of opiates and the research was carried out. Investigation revealed a diet consisting of a hamburger from Burger King the night before the specimen was taken and a breakfast apparently normal, two bagels in the college bar. Individual appears to be quite normal. They concluded that the spraying of poppy seeds just used for decoration in the bagel resulted in positive immune response.

Hemp seed food

Laboratory studies revealed that the cookies made from seeds of cannabis sativa (hemp) can cause a positive urine test for cannabis. Although the vines are low, can lead to positive after ingestion. Positive results were obtained cannabis to volunteers who ate the cookies from hemp.

Human Error

Most human errors are caused due to mismanagement, staff shortages, poor maintenance of equipment, glass products contaminated with positive samples of drugs, surveillance, etc. the quality of the work is done laboratories to ensure that no mistakes are made. The machines are as reliable as the people who operate them.

Regulations necessary

In a randomized trial or mass, without probable cause, the error is inevitable. Causes of errors in the tests:

1. Inadequate laboratory procedures
2. Involuntary change of the samples
3. Paperwork is lost or damaged.
4. Inhaling
5. Cross-reactivity with other drugs, legal
6. The sample handling
7. Unknown reasons

False Positives

It refers to a positive result on a drug-free sample. False positives can occur due to testing methodology, contamination of equipment, etc. There is a great personal and social significance in the positive drug test evaluation of physical work, prior to employment, candidates for promotion, etc. For Generally, screening is followed by a confirmation test using different methodologies.

False positives or opiates

The most difficult task for those interpreting the results of urine drug screening is the opiate positive. Most of the positive aspects of opiates due to poppy seeds and prescription drugs. Studies show that certain drugs are found after the ingestion of poppy seeds. As false positives of life interrupted several employees, Govt. has changed the mandatory guidelines for federal programs Screening by increasing the levels of cut and confirmation of opiates.

Many errors

Mistakes can be made anywhere in the process of drug testing. Employees become the guinea pigs used to develop tests that may be necessary. Operational problems at the laboratories, the defective conformation, legal action and lack of care appear almost immediately in the mass screening of military personnel for drugs.

Cross-reactivity

Was studied by Allen Stiles. They tested 161 recipes and nonprescription drugs issue and found that 65 of the prescription and sale products showed some cross-reactions, including values ​​above cut. Most of the positive requires that concentrations are not attainable in human urine and have no practical problems. If you use a prescription or nonprescription medicine before a drug test that could test positive. About 150 legal drugs, especially those containing synthetic compounds such as phenylpropanolamine have been reported to cause positive tests for amphetamine and can also cause a false positive test methedrine. Some sources claim that cocaine EMIT test can be positive if the person being tested drank large amounts of tea. If you have taken more of a pain-counter preparation or menstrual pain that could test is positive, you have to prove that he is addicted to drugs. So the cross-reactivity is a problem that has not been resolved and remains poorly understood. So, be smart, be informed, active and prepared to pass a drug test.
