Common Drug Test Panels in Modesto, CA

Given the wide variety of illicit substances available these days, numerous drug test panels are needed to effectively detect their usage. To help you identify the drug compounds that concern you most, we offer the following testing methods:

10-Panel Drug Test

The 10-panel test can detect minute amounts of 10 different drug compounds, which include:

Expanded opiates can be included: Hydrocodone, Hydromorphone, Oxycodone, and Oxymorphone

Urine Sample Drug Testing

Urine sample-based drug testing services are very widely used, as they’re inexpensive and highly accurate. These tests are best for identifying recent instances of drug use, as the body rapidly cycles through urine. They’re also highly effective for cannabis detection, as THC compounds remain in urine for up to three months for heavy long term users. Typical detection time for urine drug testing is up to five days.

Hair Drug Testing

Companies that want to detect long-past drug use should turn to hair follicle testing. This method involves analyzing a small hair sample to detect various drug compounds. Hair holds onto drug compounds for months, which makes it difficult for employees to hide drug use. Detection is from 7 days to 3 months.
