Laboratory Procedure Of Drug Testing

Drug testing is highly accurate and reliable when all features of the testing process are done correctly. If improper procedures or testing methods are used, the result can be very misleading and inaccurate. The three important aspects of good drug testing are strict collection procedures, proper testing procedures, and unplanned notification.

Drug testing must be done without notification. Specimen collection for drug testing should be done with proper monitoring or else there are chances for addicted person to mislead with other techniques. At first a screening test should be performed, which is very easy procedure, if the result is positive, then confirmatory test procedure should be done. The confirmatory test procedure is a sophisticated procedure and is done in laboratory using Gas Chromatography/Mass Spectrometry (GC/MS). If the result is positive in confirmation test, then he or she is said to have abused drug. As a particular drug has particular cutoff level, the positive result of screening test is not considered final. The result must be notified as early as possible, as it becomes late, the level of drug disappears from body and he or she may claim that they do not use drug.

Basic facts to know before investing in 2010

The recession seems to slow down and the economy is in recession mode. I’m sure lots of people will be aggressively back into the recovery mode. However, there are a few things that investors need to know before

Investing in companies relying on consumer spending, requires a cautious analysis. It is unlikely that the consumer spending is going to get back to its normal position as the experts are doubtful on the unemployment rate. Though the recession is slowed down there are no signs of decrease in unemployment rate. Some experts say that it may further increase.

We have already seen the fall in dollar in the international market. Experts say that the dollar is going to run slow and the commodity prices at high.

The interest rates are going to remain low. Federal Reserve announcing the extension of low short-term rates serve as hint for this.
