Quick Fix 4.0 was introduced in late 2003, replacing the 3.0.

I've read on other boards that some nurses, med assistants at collection facilities (surly facisits) are smelling the QF and making people pee again. These situations are exceptions. Collectors at facilities are not supposed to make judgement calls on urine and it is entirely against the protocols set up by SAMSHA, Quest, LabCorp and other labs that test.
A lack of odor is present in some human samples too. There are no standards set for urine odor. Therefore, its improper for a collector to reject a sample on the basis of a lack of odor, without running the appropriate integrity checks first. However, a collector can flag a sample if a bleach odor, or similar is detected.
