What does the Drug Test Report Mean?


Now that you have submitted your hair sample for the drug test to be done, another concern includes knowing the outcome of the drug test. The drug test report will make you acknowledge three different results. Those are-

Positive– A positive drug test report signifies that some elements of drugs are found in your hair follicle. Therefore, after getting a favorable report, the hair sample is sent for further tests, which are gas chromatography and mass spectrometry. It happens within the next 72 hours. Various other tests are then done before finally accusing the person of drug consumption.

Negative– You are saved from pain and botheration if you get a negative drug test report. A negative hair drug test report means that you have passed the drug test and that the drug test report came clear and clean. You can get a negative test report in 24 hours after all kinds of screening are suitably done.

Inconclusive– Another word you can see on your drug test report is “inconclusive.” Apparently, an inconclusive drug test report means that the hair sample given to the laboratory is not capable enough for screening. When no conclusion can be drawn from the drug test, you will get an inconclusive report. After this, you will be asked to submit another hair sample.

Hair follicle drug test detection time?

Drug testing on hair follicles finds substances or metabolites in a hair sample. A drug metabolite is a chemical produced in the body during the breakdown and elimination of a drug.

Drug tests using hair follicles provide a more comprehensive detection window than other tests. Even though drug use and abuse may not become apparent in the hair for 7 to 10 days after exposure, once it does, it stays there for weeks, months, or even years. Hair follicle drug testing may reveal drug exposure patterns, but it cannot identify active intoxication.

The window of detection is the time drugs may still detect in hair. The quantity and frequency of drug use or abuse and the pace at which the drug is metabolized in the body affect how long the detection window is. For many months after a person’s last drug exposure, certain substances may still be found in newly growing hair.

The quantity of hair examined affects the window of detection as well. Even though lengthier samples of hair may use to test for drug exposure over more extended periods, a typical scalp sample of 1.5 inches of hair can provide information about roughly 90 days of previous drug use. The detection window for a hair sample collected from a different body area where hair grows more slowly may be up to 12 months.

How to read a hair follicle drug test?

Drug testing on hair follicles may provide positive or negative findings. Positive test findings mean that the hair sample submitted for analysis contained a drug or its metabolite.

Negative test findings show that the hair sample contained no drugs or metabolites. Negative results imply that a person did not use the prescription that was the subject of the test, that they did so outside the test’s detection range, or that they did not use enough of the substance to leave enough hair for the test to detect it.

Understanding the testing procedure employed in the laboratory may be helpful when interpreting the findings. Similar to or significantly modified versions of the laboratory procedures used in more popular types of drug testing, such as urine drug testing, are utilized in hair follicle drug testing.

Drug testing laboratory techniques are often classified as initial or confirmatory methods:

Immunoassays are a popular technique for drug testing. However, they only provide early findings. The drugs or drug classes found over the lab’s limit for positive findings are included in the results. Positive test findings should be followed by testing using a confirmatory test technique to lower the chance of incorrect results on the first test.

Confirmatory test procedures: Confirmatory test procedures, including gas or liquid chromatography, provide more thorough findings than preliminary test procedures, including details on individual metabolites found in hair.

Hair follicle drug test cutoff levels?

For the 5-panel test, screening cutoff values were determined according to the laboratory’s regular procedures: GC/MS confirmation cutoffs were one pg/mg for marijuana, 500 pg/mg for cocaine and amphetamines, and 300 pg/mg for opioids. The following dosages are given for various drugs: 0.30 pg/mg for the carboxy-tetrahydrocannabinol (THC) metabolite, 500 pg/mg for cocaine, and 50 pg/mg for cocaine metabolites (benzoylecgonine; norcocaine), 500 pg/mg for amphetamines, methamphetamines, and 3,4-methylenedioxy-N-methylamp Thus, only morphine, codeine, and heroin were tested according to a study.
