REFERENCE INTERVAL/RESULT INTERPRETATION: Not Applicable

LIMITATIONS/INTERFERENCES:

• The cut-off levels used by Omega Laboratories for hair testing are based on the Federal Recommendations issued April 2004. Our interpretation of these levels is that they are designed to catch repeat usage - IE a single usage of a drug may not result in a positive hair test.

• Since hair testing covers a much longer timeframe than urine (90 days vs. 2 - 3 days for drugs), the intent is to show more of a pattern or lifestyle choice of usage. While a negative hair test cannot necessarily be used to disprove a laboratory-confirmed positive urine test, it can still show that the donor is at least not a chronic or frequent user of the drug.
