Saliva Drug Testing The FDA has recently given Epitope, Inc approval to begin manufacturing saliva drug testing. In a study using RIA (Radioimmunoassay) test, cannabinoids were detected in saliva 4 to 10 hours after subjects smoked a single marijuana joint. Epitope has recently developed a test which detects drugs or their metabolites in saliva. However, this sort of drug testing is limited to detecting very recent drug use. In one study, saliva testing was only able to detect cannabinoids 4-10 hours after the subjects had been smoking. It is likely that this drug testing will be confined to detecting current intoxication only. "Saliva drug testing has been touted as a "fitness for duty" test, as its window of detection begins as soon as a drug is ingested. Saliva drug testing will reveal only current or very recent (within the past twelve hours) marijuana use, but will detect use of cocaine, opiates, methamphetamine and Ecstasy over the past two to three days (urine will detect these drugs for three or four days after use). Saliva is typically experienced as cleaner and less intrusive than urine, and there are currently no known methods for defeating saliva drug testing. Saliva drug testing testing is useful for pre-employment, random, post-accident and for-cause testing. Both lab-based and on-site systems are available; the on-site system offers results ten minutes after taking the saliva sample. Saliva tests compare favorably in price to urine testing. " In oral fluid, drugs will be detected within minutes after use. In urine drug testing, drugs will remain undetected in the first 4-8 hours. * Marijuana 12-24 hrs * Opiates 24-48 hrs * Amphetamine 24-48 hrs * Methamphetamine 24-48 hrs * Cocaine 12-24 hrs

To abstract blood for DNA testing at home, you would first need to purchase a DNA extraction kit that is designed for at-home use. Follow the instructions provided with the kit to collect a small blood sample. It typically involves pricking your finger and collecting a few drops of blood onto a special collection card or tube. Ship the sample to the testing laboratory according to the kit's instructions for analysis.
