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. Sample collection is directed to a local site by AMH Nationwide. Samples are sent to one of five national labs: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, or ExperTox. Initial screening and confirmatory testing occur at the labs. Certified Medical Review Officers review all non-negative results. PROCESS ## 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](https://amhnationwide.com/hair-follicle-drug-test-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. Sample received and logged by the lab. Initial screening completed within 3 to 5 days. Non-negative samples sent for confirmatory testing, adding 3 to 7 days. Medical Review Officer reviews non-negative confirmed results. CONFIRMATION ## 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. Uses GC-MS or LC-MS/MS for definitive identification. Ensures false positives from initial screening are excluded. Reviewed by a certified Medical Review Officer for clinical interpretation. POTENTIAL DELAYS ## 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. Sample quality issues requiring recollection. Delays in courier or shipping services. Laboratory backlog due to volume or technical issues.
