Based on the creatinine concentration of the specimen, the MRO may request the employee take a second test in the same manner as the first or they may request recollection under direct observation. According to DOT, only one recollection is allowed, and the second collection becomes the recorded result — even if it is another negative dilute.
In other words, you are not permitted to require the employee to take an additional test. To prevent or reduce instances of diluted test results, share the following tips with your employees to help them prepare for testing:.
Home Negative Dilute — Now What? What does it mean? What are the causes? There are several possible causes for a urine sample to become diluted. Among these are Being overly hydrated, which comes down to drinking excessive water. Secondly, the individual may have health problems involving the kidneys which can result in a release of too much water in the urine. Creatinine is a compound produced when an individual metabolizes creatine.
First of all, if a test comes back as a positive dilute, that means that the client has drugs in his or her system. It means that while there was more than the usual amount of water in the sample, the presence of drugs was still there. However, if the test comes back as a negative dilute, this does not automatically mean that drugs were present in the urine sample.
It simply means there was too much water to tell one way or the other. The laboratory might ask the client to submit another urine sample, and to not drink anything beforehand.
Diluted drug test results make it difficult to determine if the participant is using drugs, as they may provide inconclusive results. There are two types of dilute specimens: positive and negative.
A dilute specimen is a urine sample that has higher water content than the average specimen, which minimizes the drug levels visible in the urine. Sometimes dilution is intentional, but it can happen accidentally as well. If the drug levels do not reach a certain cut-off point established by the laboratory, the specimen will not be marked positive for the drug even if it is detected. Below we explore what causes diluted drug test results and how you can prevent specimens from being diluted.
Most diluted drug test results are produced unintentionally by the participant. This can occur when an applicant consumes an excessive amount of fluid, diluting the concentration of urine in the sample.
However, it is also possible for specimens to be diluted on purpose by someone who hopes to cheat the test and hide their drug use. The participant could 1 intentionally ingest lots of fluid or 2 pour fluid directly into their urine sample. Both techniques will lower drug ratios in the urine, and the laboratory will detect the diluted drug test results. Neither technique guarantees a negative result.
