How Far Back Does a Lab Urine Test Go?

Drug tests are one of the most effective ways to find out if someone is using drugs, whether it’s for work or for personal reasons. There are different kinds of tests. However, the urine drug test is the most popular because it is easy to use. It doesn’t cost much and works well. “How far back can a urine drug test find drug use?” is a question that a lot of people have. This blog post will discuss about how far back different testing methods can find drugs. It will focus on 4-panel, 6-panel, 8-panel, and 13-panel tests.

How Far Back Does a 4-Panel Drug Test Go?

A 4-panel drug test is usually used for basic checks, like when someone is applying for a job or going to court, apart from it, you can also take professionals 5-panel drug and 10-panel drug testing services. It can find drugs like cocaine, marijuana (THC), opiates, and amphetamines that are overused most often. This panel’s urine drug test has different detection windows for each drug and the amount of time the person uses it. Most drugs can be found for a shorter time in people who only use them sometimes. However, for people who use them all the time, the effects may last longer. For example, cocaine can be found for two to four days, marijuana for three to thirty days, opiates for two to four days, and amphetamines for one to three days. The time it takes to test positive for most drugs is pretty short, but heavy users can test positive up to 30 days after using.

How Far Back Does a 6-Panel Drug Test Go?

The 4-panel drug test is more limited than the 6-panel test because it doesn’t look at benzodiazepines and barbiturates. This kind of drug test is often used for more thorough checks where abuse of medicinal drugs is also a worry. A 6-panel urine drug test can usually find drug use between 2 and 10 days for benzodiazepines and between 2 and 4 days for barbiturates. Other drugs, like marijuana and cocaine, will also show up in the same amount of time as the 4-panel test. If someone uses weed regularly, it can take up to 30 days longer to be detected.

How Far Back Does an 8-Panel Drug Test Go?

An 8-panel drug test goes even further because it checks for drugs like methadone and propoxyphene. When opioid medicines or treatment drugs might be a problem, these other drugs are often tested for as well. Compared to propoxyphene, methadone can be found for only 1 to 2 days, while it stays in the body for 7 to 10 days on average. The general discovery period for most drugs in this urine drug test is still pretty short, normally between a few days and a week. The only drug that can stay in the system for a much longer time is marijuana.

How Far Back Does a 13-Panel Drug Test Go?

The 13-panel drug test is one of the most thorough tests out there. It is often used in high-risk jobs or other cases where a wider range of drugs needs to be screened. There are 13 panels in the test, and they look for drugs like ecstasy (MDMA), methamphetamines, PCP, tricyclic antidepressants (TCAs), and fake painkillers like oxycodone and hydrocodone. Different drugs have different detection windows. However, for most of them, a urine drug test can find use within 2–10 days. Methamphetamines and ecstasy, on the other hand, can be found for two to four days, while PCP can be found for up to ten days. Depending on the drug, synthetic opiates can stay in the body for two to four days.

How long drugs can be found in pee can also be affected by things like body mass, age, and how well someone is hydrated.

Professionals in the medical field, the legal system, and companies all like them. This is because they are quick and cheap ways to check for recent drug use.

For example, someone who uses marijuana often can have it in their system for up to 30 days. However, drugs like cocaine, opiates, and amphetamines are usually only found for 2–4 days.
