Blood Drug Testing

If you've been involved in an accident, DUI, or you've been injured on the job, you may be asked to take a drug test to test for the presence of alcohol or other illegal substances. In these cases, blood drug testing is usually performed because this is the only accurate method for determining legal intoxication. If you've been involved in a work-related accident and your blood drug test is requested by an insurance agency, you'll probably be taking a urine drug test as well.

Blood drug testing has limitations and the process is considered to be invasive by many people. This method for testing offers a small window of time for detection. This type of test has to be given by a qualified individual in a controlled setting in order to be valid. Additionally, the expense involved with blood drug tests make administration less practical for general use in employment screenings.

Drug blood tests are designed to test for the presence of drugs at the time your test is taken. These tests can also be used to determine whether or not you have current health issues in conjunction with screen for drugs. Some conditions commonly tested for include, cholesterol levels, hepatitis, HIV, AIDS, and diabetes. This type of test can allow for more flexibility in the types of tests and detection of the levels of substances. This can offer more insight into how often someone uses a specific substance.

Blood drug tests have a much shorter time for drug detection than other types of drug tests. This test detects the presence of drugs, not drug metabolites that the body creates. In most cases, drugs are only present in the blood for a very short period of time. The time that drugs remain present in your blood can be as little as a few hours to a few days.

Of course, there are exceptions. Long term use of marijuana can be detected in the blood for as much as 7 days. Nicotine and opiates can also be detected for several days.

Blood drug tests can have different cutoff levels for detection which can affect the length of time that the drug can be detected in your system. It's impossible to know the sensitivity levels of the test used by each lab; betting on the minimum time for detection may not be an effective method for avoiding a positive result. Because of this limitation, blood drug testing is not widely used for employment.
