First check drug test faint line

We get many questions about faint lines. Although there is no single factor which leads to faint test lines, the following are examples of possible causes.

The composition of urine specimens from person to person can vary widely depending on health, fluid consumption, and medication intake of the donor.

Likewise, the composition of urine specimens from an individual donor may vary depending on the time of day and other factors. As a result of this inherent variation, the possibility exists that any donor may yield a urine specimen with a composition that produces faint test lines on certain immunoassays. Although they may not produce the same effect in the body, some medications are chemically similar to the drugs detected in a rapid drug screen test.

If a compound is similar enough in structure to the drug being tested, it is possible that the presence of that compound could lead to faint test lines or even a false positive drug screen result. This phenomenon is one of the primary reasons why presumptive positive drug screen test results should be confirmed by an alternate methodology.

In the most sophisticated products, as many as 12 drugs can be identified by a single drug screen device. For instance, some rapid drug assays are naturally lighter in line intensity than others.

Most often, the light-line phenomenon is seen in THC metabolite tests although drug-class assays such as Benzodiazepines or Tricyclic Antidepressants can also be affected. If this is the case, it is still critically important to note that the concentration of the drug is very likely below the cutoff level of the test, which indicates a negative result.

Cleaning Your System Of Weed // THC Detox

Thread starter Texag Start date Nov 4, Texag Member. I get tested for my probation on the November 10th. I smoked a few times a day on Oct. I'm not sure if it's just really faint kit says that's still negativeor a ghost line which would mean I tested positive. I'm really freaking out, so any help would be greatly appreciated. Also, if it is positive, what could I do to ensure I piss clean when I take the real test?

Kerovan Well-Known Member. No thats bullshit. When i was in the marine corps i slipped a few time's after we came back from deployment and took a few hits.Post a Comment. Negative or Positive Test Result? I have found this to be a very common question with people who are worried about seeing a faint line on the home reagent dip strip test.

Sometimes a lab will use a reagent stick validation before "accepting" the sample to sent to the labfor drug screening. What Does the Faint Line Mean? When reading the drug test result, you will find a line at the very top of every testing window and that is the control region C. The test is not considered valid without this line. Result is considered negative when a colored line appears in both the control C and test T region.

If the colored line appears in the control region but not in the test region, the test is considered to be positive.

Faint Line on Drug Test: Meaning and Causes

Nevertheless, presence of any faint line in the test region T will indicate negative results no matter how light it is. The color intensity of the line in a drug test result must not be confused with the quantity of drug present in the body. A positive urine drug test requires presence of minimum drug quantity in the urine specimen.

The lower the minimum amount thresholdthe lighter the line will be in negative urine. So a dark line is a high threshold and a faint line is a low threshold but still a negative. Now for the bad news. Labels: creatininecupfailfainthomelinepassphscreenselftestthcurinevalidation. No comments:.

Just took home drug test.... Is this passing, or a ghost line?

Using this test is as easy as Collect sample. Attach test lid, rest cup on legs. For in vitro diagnostic use. Bought this exact test just to make sure if my prescription Zoloft was giving me false positives for Benzo, took the test and passed all 12 drugs tested with flying colors. So I initially freaked out, as I was to take a real drug screen for a job. Went to the Lab to take the test and it was negative.

It scared the heck out of me. Yes, I take Xanax, but not recreational, but stopped for this job and lost it when it came out positive on this test that I bought from Walmart. So can recommend, and that is my story on this First Check. I do recommend if you are taking a drug test and want results before the test so you can clean your act up.

Here at Walmart. Your email address will never be sold or distributed to a third party for any reason.Answers to Common Questions. What does each panel represent? Codeine, Morphine Does a faint line indicate a negative result? Yes, faint lines do indicate negative results.

The presence of a test line, regardless of how light, indicates a negative result. Some test lines tend to run naturally lighter than others, for example 3.

You are more then welcome to send the specimen to the laboratory for additional testing if you are not convinced the result is negative, however, the intensity of the line plays absolutely no role in the At Home Drug Test. Why did the laboratory report the specimen as negative when I had preliminary results at home?

The test device, like all screening tests, is meant to distinguish negative urines from those that MIGHT contain drugs. The screening device often detects many of the drug breakdown products contained in urine. If there is not enough of that ONE specific compound, the lab will report the urine as negative. How long does Marijuana stay in the system if the person is not a chronic user? Occasional users: up to 10 days but may be as early as days. There are a lot of variables involved and that makes it difficult to project exactly how long the drug will remain detectable in a particular individual.

Why do some lines show up fainter than others? There is a minimum amount of drug that has to be present in the urine specimen in order for the test device to consider the urine positive. The lower the minimum amount, the lighter the line will be in negative urine. Does a faint line mean there is some drug present in the urine? The presence of a test line, regardless of how faint, indicates a negative result. Even if there is some drug in the urine, if the line is present, the urine does not have the MINIMUM amount of drug needed to consider it positive, so it is considered negative.

The laboratory test also relies on minimum amounts. Will I get the same results from another laboratory? The laboratory that performs the confirmation testing is one of only 70 laboratories in the United States certified to perform regulated drug testing. A majority of employment, Federal government and criminal justice drug tests performed in the United States are done at those 70 laboratories. My child admitted to using drugs a week ago, but I got a negative result.

Most drugs are eliminated from the body within a few days, with the exception of chronic marijuana use.The kit employed for urine drug test is reliable yet a cheaper way of screening the drug abuse. Every drug test involves a predetermined detection level which can tell if a drug test is positive or negative.

At times, people get a faint lineon drug test which may be due to several possible reasons that will be further discussed here. When reading the drug test result, you will find a line at the very top of every testing window and that is the control region C. The test is not considered valid without this line.

Result is considered negative when a colored line appears in both the control C and test T region. If the colored line appears in the control region but not in the test region, the test is considered to be positive. Nevertheless, presence of any faint line in the test region T will indicate negative results no matter how light it is. The color intensity of the line in a drug test result must not be confused with the quantity of drug present in the body.

A positive urine drug test requires presence of minimum drug quantity in the urine specimen. If the minimum amount is low, there will be a faint line on drug test. The urine composition differs slightly for each individual mainly because of the medication intake, fluid consumption and overall health. The urine test result of the donor may exhibit faint lines within the time limit on some immunoassays.

The test results will be considered negative of course. Some OTC drugs are chemically similar to the drugs that are screened in the rapid drug test. Due to the similar compound as that present in the drug being tested, the faint line might appear in the test region T or may even lead to false positive result.

This is one of the main reasons why counter checking with other techniques is often necessary. When performing a drug test, screening for multiple drugs, up to twelve, may be done simultaneously. As a result of this, it becomes difficult to remember each assay as an individual diagnostic test like some drugs may exhibit a lighter line. Due to this assays of tricyclic, antidepressants and benzodiazepines may also get affected.

At times, faint line on drug test maybe due to the presence of a little quantity of drug remaining in the urine sample especially in TCH screening test. If the drug concentration is below the cut-off level, the result will be considered negative. My child confessed he used drugs a week back.

H oweverthe test result was negative. Some drugs take a few days to eliminate from the body, except marijuana when used chronically. According to the studies, some amount of drug does get inside the body due to exposure to secondary smoke of marijuana.

A big fat no! Toilet urine may become diluted and has a chance of exposure to cleaning agents that may alter the result. If I drink plenty of water, will it affect my result of the urine test? Water may dilute the urine specimen. It only works if you are really close to the cut-off level. Dilution is also considered to be a cause of faint line on drug test.

Interpreting Test Results

If the test is valid, the line will appear in the colored region. The appearance of line in the test region will indicate negative results whereas no line will appear if the result is positive. You must wait for at least five minutes. What should I do in case of positive results?

Try following the instruction when doing the drug testing. The urine must be fresh and undiluted, dipped up for 10 seconds at least.Faint lines on drug tests are very common no matter what method of screening is being used. It's crucial to understand how to interpret drug test results, including faint lines, in order to make confident decisions and prevent liability claims for inaccurate results.

Drug test results do not vary based on the intensity of the colored lines. This means that even if the line is very faint, the test has not found any trace of that specific substance.

A negative drug test does not necessarily mean the donor has never used any of the substances being screened. In order for a test result to be positive, a certain quantity of metabolites is required to react with the built-in test strip reagents. Most home drug tests are FDA Approved to perform just as well as corporate drug tests.

A very faint line on a home drug test is indicative of a negative test result, as mentioned above. Instant drug tests are designed for easy interpretation. Both integrated urine test cups and saliva drug tests contain built-in strips that react to drug metabolites present in a donor's sample.

Each test strip features a Control line, to indicate the test is functioning properly; and a Test line, which will only appear if drugs have NOT been found for a particular substance.
