The test will show the presence and quantity of specific drugs in the body. Definitive analytical techniques are used to guarantee the accuracy of the test result. Blood testing usually used to detect the presence of opiates. The urine test shows the presence of cocaine, barbiturates, amphetamines, some opiates, and other street drugs.
You need to arrive at the testing center with a full bladder. This means that you need to hold your urine for two hours before the appointment to give the best sample. The result will be sent to you via email.
Common symptoms of drug abuse include agitation, slurred or slowed speech, panic, small or dilated pupils, nausea, paranoia, delirium, changes in heart rhythm or blood pressure and difficulty breathing. A drug test usually requires you to give a sample of your urine in a lab. Your doctor will provide you with instructions on how to get a clean catch sample.
Wash your hands first. Use a cleansing pad given by your provider to clean your genital area. Women have to open their labia and clean their genital area from front to back. Men have to wipe the tip of their genitals. Move the container under the urine stream and collect at least one to two ounces of urine. The container should have markings to show the amount. Finish passing the rest of your urine in the toilet. Give the collection container to your health care provider or lab technician. The presence of a medical technician may be required while you give your urine sample.

The risk of a false positive is almost zero. However, there are instances when a drug test can have a false positive result. Some decongestants that contain ephedrine can lead to a false positive result for amphetamines. In extremely rare cases, the consumption of poppy seeds can give a false positive result for opioids. Provide the clinic with a thorough and precise history of any herbal drug use or prescription medication you are taking to get the most accurate results.
