Your home kit is not as accurate as many professional methods. If you are working for an industry where security is very tight, then they might pay for high end tests. Some tests can also detect masking compounds, but again this is unlikely for most jobs..

Actually, specimen integrity checks have become SOP in most employment-related U/A's since the rise of adulterated/substituted/diluted samples.

The "masking compounds" all rely on copius amounts of fluids, which is mere dilution. The dilution factor is what serves as the "mask".

Since they function on the same principle, the instant assays used by the labs for the initial screening are no more reliable or accurate than the home test kit.

A failure due to being too diluted just means a retest.

Not always so. In pre-employment situations, there are employers that wont accept a "too-dilute" test result and just simply move on to the next applicant for hire.
