DRUG DETECTION TESTING

Discovery times in urine are significantly greater than the time of discovery in the blood, which is also usually much more expensive. The presence of a drug or drugs in urine does not provide information as to whether the individual is actually under the influence over a particular time. Likewise, no determination can be made from the urine as a total dose or time of dose.

Blood tests, on the other hand can provide more useful information on whether an individual is "under the influence", although this may not be conclusive in all cases.

The accuracy of medical tests of urine is variable depending on how the tests are done. Medicine tests are very accurate and reliable when all aspects of the testing process are done properly. Moreover, the information obtained can be very misleading and inaccurate when poor procedures or testing methods are used. Medicine tests are reliable only when the consumer knows how they should be made and then require the industry to be done properly drug testing information.

Unfortunately, today, most medical evidence is badly done and annoyed with unreliable information. Below are issues that should provide enough information to allow consumers to demand proper testing procedures. There are three aspects to reliable medical evidence:
Strict collection procedures;
Appropriate testing procedure;
Notification arbitrary.

Specimen Collection: Collection of Urine should be done after the positive identification process of the individual and full chain of custody procedures. Moreover, and most importantly the specimen should be certified by a means of measuring temperatures with a digital thermometer. Acceptable varieties of temperature measurement should be within 96 to 99 degrees to prevent adulterated samples are replaced me.

Attested collections are not needed and in fact are not as reliable as the digital measurement of temperature within 96 to 99 degrees. (If the collection is attested fact, she should also make digital measurement).

The "temperature plastic strips" that are attached to the bottle should not be used to measure temperature. The current widespread practice is for collection facilities to allow certification of temperatures within a range from 90 to 100 degrees Fahrenheit. It is also common to use "temp strips" for the determination of the temperature. These practices do not prevent adulteration and / or replacement of the specimen and are probably the source of most of the inaccuracy and inconsistency of medical urine test today.

SAMSHA (Substance Abuse Issues Administration Mental Health Services) has encouraged these practices without being aware defective declaring these broad limits (90 to 100 degrees) of the admissibility of temperatures within the regulations. This has raised the national incompetence in this area, allowing subjects 'positive' to substitute or adulterate his urine tested and causing undetermined number "of false negative results.

The procedure of the DDL for the collection of specimens is available to any library facility that wants to improve its procedures for collection (see the collection of specimen).

Testing Procedure:

Ensure that all positive results are confirmed by GC / MS Analysis LC / MS. This is critical to ensure that no "false-positive results occur.

There are two approaches to test, test limit type and limit discovery test. A test type has a set limit "limit" administrative to report a positive result. If medication is identified, but is below the threshold, is told as "undiscovered".

THE EXTENT OF DISCOVERY - the limit of discovery evidence tells any detectable amount present within the capabilities of the laboratory. This is typically low "limits" over administrative spoken. Test results 'negative' most reliable are those that are determined by a test procedure of zero tolerance. SAMSHA certified laboratories are required to adhere to established threshold concentrations. In other words, a specified amount of medicine or drugs is allowed to be present and still be told as "negative. This again causes an increased number "of false negatives," or the report of a test result as "negative" when the drug is actually present.

To provide the most accurate and reliable test "negative", a zero-tolerance test should be done. Require that the laboratory follow the zero tolerance limit for requesting the discovery of medicine and medicine be governed by the procedure LIMIT DISCOVERY GC / MS. If the laboratory can not accommodate this request, find another lab that is certified. (SAMHSA laboratories shall not engage in zero tolerance testing because regulations require that the boundary limits were set in a row).

Zero tolerance tests may also be more expensive but provide the most reliable if the tests are "negative" (assuming of course that the specimen was collected properly).

Arbitrary Call: arbitrary notification is an important aspect of the reliability of medical discovery. The discovery of any medication is subject to timing and amount of dosage. Individuals who have used illicit drugs can allow the system to be cleared if they have enough time. The notification of the individual should be made not to allow plenty of time allows the person cleaning the medicine. Usually a limit of 24 hours is acceptable for most discovered drugs other than alcohol (ethanol). If ethanol is the concern the collection should be done within 3 to 4 hours.
