Drug Test Panels in Torrance

Confidential Panel Testing Backed by More Than a Decade of Experience

A drug test panel groups several substance categories into one screening request. The correct panel depends on instructions from your employer, court, agency, school, attorney, or testing program. Confirming those requirements before collection can help you avoid ordering the wrong test.

At Fastest Labs of Torrance, we provide confidential drug testing for individuals and organizations. Our certified collectors can review your instructions and complete the collection in a clean, professional setting.

5-Panel, 10-Panel & 12-Panel Drug Test Options

Panel numbers describe the breadth of the screening, but exact substance categories can vary by specimen method, laboratory, and testing program. We’ll match the order to the requesting party’s requirements rather than assume a broader test is automatically appropriate.

Common panel levels include:

5-panel drug test: Provides a narrower standard screening scope for requests that specify five drug categories.
10-panel drug test: Expands the screening beyond the five-category scope.
12-panel drug test: Adds two categories beyond the 10-category scope when a broader screening is requested.

Bring the written order or describe the purpose of the screening when you contact us. We can verify the available configuration before collection.

Clean Facilities, Short Waits, & Certified Collection

We maintain clean, inviting facilities and strive to keep wait times under five minutes without compromising secure procedures or confidentiality.

We serve individuals, small businesses, schools, and government agencies. For employers, we also assist with workplace drug testing programs through policy creation, implementation, and ongoing management.

What to Expect During Panel Drug Testing

We begin by confirming the requested panel, specimen method, and documentation requirements. The requesting organization’s instructions determine whether you need rapid screening, laboratory testing, chain of custody, or another review step. Chain of custody is the documented record of how a specimen is collected, handled, and transferred.

A typical testing visit includes:

Request verification: We review the order and identify the specified panel and method.
Identity confirmation: We verify the donor and required documentation before collection.
Specimen collection: A certified collector follows the applicable collection and security procedures.
Result reporting: Results are communicated according to the selected test and requesting party’s requirements.

Many rapid drug screens provide immediate screening results. When confirmatory laboratory testing is required, results may take one to three business days. Timing also depends on the specimen type, laboratory analysis, review requirements, and whether the initial screen is non-negative.

For random screenings and ongoing workplace programs, we also offer mobile, on-site testing. We can discuss the testing method and program structure that fits your organization’s requirements.

When You May Need a Panel Drug Test

Common testing situations include:

Pre-employment and workplace screening: Testing conducted before hiring or as part of a random, post-incident, or reasonable-suspicion program.
Court-related testing: Screening ordered through a court, probation program, or attorney.
School or agency requirements: Testing that specifies a particular scope or documentation process.
Personal testing: Screening selected according to the individual’s purpose and the information needed.

How to Choose the Right Panel Size

A larger panel isn’t necessarily the right one. A 12-panel test screens more categories than a 10-panel test, and a 10-panel test covers more than a 5-panel test. However, the requesting party’s written instructions should guide your selection.

Before choosing a panel:

Check whether the order names a specific panel number.
Look for required substance categories, specimen methods, or documentation.
Confirm whether the request calls for rapid screening or laboratory testing.
Ask whether chain-of-custody documentation or a formal review process is required.

Don’t substitute a broader panel without confirming that it satisfies the order. If the instructions are unclear, have them available when contacting us rather than choosing based on the panel number alone.

Specimen Methods & Result Timing

We offer urine, hair, saliva, fingernail, and sweat or skin patch drug testing methods. Specimen choice affects the collection process, detection period, turnaround time, and suitability for the stated purpose.

Choosing a Specimen Type

Available specimen methods include:

Urine drug testing: Commonly used for many screening programs, with the applicable scope determined by the order.
Hair drug testing: Uses a different detection period and collection method than urine or saliva testing.
Saliva drug testing: Provides another collection option when it matches the testing instructions.
Alternative specimens: Fingernail and sweat or skin patch testing may suit certain purposes and timelines.

Rapid Screening & Laboratory Confirmation

Rapid screening and confirmatory laboratory testing are separate stages. A non-negative screening result may require laboratory confirmation before a final interpretation is reported. The specimen, findings, laboratory process, and required review all influence the final turnaround time.

Schedule the Correct Drug Test Panel

Whether you know the required panel or need us to review your instructions, we offer confidential collection in a clean facility with a focus on efficient service. Have your order available so we can identify the appropriate option and documentation before your visit.
