Recent Ingestion Of The Drug – Forensic Urine Drug Test
The drugs that you take in through the oral cavity are absorbed through the gastrointestinal mucosa and reach the blood within minutes. Then it circulates in blood till its half life gets over and exerts its maximum action at its desired site and is finally metabolized in the liver or kidney or both and is excreted in urine. Thus the maximum duration of detection of drug in blood is from the point of appearance of drug in blood to its disappearance which is very short and the drug leaves blood within a day.
The most advantageous part of blood drug testing is that the presence of drug in blood denotes recent ingestion of the drug. Moreover the specimen collection is easier with blood than urine as it is not all that embarrassing. The blood sample can be collected under supervision and the need for rest rooms or private places is excluded. This also excludes the possibility of contamination of specimens.
One disadvantage of blood drug testing over its urine counterpart is that the drug can be detected for a longer period in urine than blood. And the drugs in blood can be cleared much faster than its original duration by using detox products.
Serum is a very effective alternative for blood. The whole blood is collected in containers or tubes having an anticoagulant which is mostly EDTA and the sample is tested for drugs using the rapid drug testing kits which takes few minutes to give accurate results.
Doing blood drug testing is the ultimate after the preliminary screens show up to be positive. Drug test strip with for forensic urine drug test or OrAlert oral saliva test or oratect oral screening seems to the common mode for drug testing. Once the preliminary tests are positive then higher levels of tests are performed.
