Drug Screening
Split samples in drug screening
An advanced and safe drug screening methodology would be to collect the split samples in split specimen cup at the time of the primary sample collection. Split sample cup is an integral part of any corporate drug screening kit to prevent any possible contamination of the sample during the test process. Even if one part of the sample gets contaminated the other half of the sample, which will be collected in a split specimen cup would still be unhandled and uncontaminated and would be available for wholesome use as a pure uncontaminated specimen.
Split sampling collection for any drug screening is important because there are many chances that can validate a need to make more than one testing for a sample. Drug screening policy requires the sample to be tested more than once if it tests positive for a drug to avoid false positive confirmations.
A true drug screening fact is that samples are sent to laboratory for confirmatory test or retesting in cases where the person tested advocates telling that the results are false positive or due to wrong handling of the samples. In such cases, though a drug screening hair test can be obtained, laboratories adopt to do a different method of testing with the split sample that they have. Only after the sampled person further argues about being not guilty over again, a hair test would be warranted.
Traditional specimen collection methods did not have a provision for being able to collect samples separately. All they did was to collect the sample in a specimen cup, take it to the laboratory and split the samples in to further different small cups, to retain some untouched samples to handle discrepancy, such collecting methods had a disadvantage of the samples getting contaminated at the time they get transferred to further small units of samples. The split specimen collection cup eliminates such complexity and provides wholesome security from the sample getting contaminated due to splitting them to small units. Even if it does occur there is always going to be the split specimen for revalidation of the tests.
In the split sampling method the sample is tested for a drug, if it is turning out to be negative, them the sample is dumped, but if the result is going to be positive, it will be sealed and will be sent for further high level analysis to the labs.
