If you were reading the posts for a solid 3 weeks like you said you did, you likely wouldve discovered that..

A) gender is not tested in a urine sample collected for a drug test.

B) as long as your QF batch was unexpired (which is the case with yours) and kept away from exposure to direct sunlight, it wont be ruled a "non-human" sample.

Whether a "diluted" sample results in a retest depends on your employer. On pre-emp situations, some will grant a retest while others may simply move on to the next job candidate for hire.
