9-Month Hair Drug Test: Results Timeline | AMH Nationwide
9-Month Hair Drug Test Results Timeline for Reliable Turnaround
The 9-month hair drug test results timeline typically spans 7 to 14 days from sample collection to final report. Non-negative results undergo confirmation by a certified Medical Review Officer, which may extend processing time. Delays can occur due to sample issues or lab backlogs. Call (877) 731-6362 for detailed information.
What is the typical turnaround time for 9-month hair drug test results?
The typical turnaround time for 9-month hair drug test results ranges from 7 to 14 days after sample collection. This timeframe covers the entire process from receiving the sample at one of the five national lab networks to delivering the final report.
What happens during the 9-month hair drug test results timeline?
After collection, the hair sample is shipped to the designated lab for analysis. The lab performs an initial immunoassay screening to detect drug metabolites within the 9-month detection window. If the initial screen is negative, results are reported promptly.
If the initial screen is non-negative, the sample undergoes confirmation testing using gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS). This process ensures accurate identification of substances.
How does confirmation testing affect the 9-month hair drug test results timeline?
Confirmation testing is required for any non-negative initial screen to verify the presence of drugs. This step extends the timeline since it involves more sophisticated analysis techniques and quality controls.
The confirmation phase typically adds 3 to 7 days to the overall timeline, depending on the substance and lab workload.
What factors can delay the 9-month hair drug test results timeline?
Several factors can delay the reporting of 9-month hair drug test results. Common causes include insufficient or contaminated samples, shipping delays, and high lab volume. Additional confirmatory testing or administrative reviews may also extend processing times.
