How to Tell What Your Urine Drug Test is for

Urine Drug Test: What Am I Being Tested For?

 (Panel Codes & Abbreviations Explained)

If you’ve ever looked at a urine drug test form, you’ve probably noticed a mix of numbers, abbreviations, and codes printed at the top. For most people, these labels are confusing — but they actually tell you exactly what substances are being screened.

Understanding your test panel helps you know:

• What drugs are included
• Whether THC is being tested
• If extended opioid testing is included
• Whether specimen validation checks are used
• How strict the testing process will be

This guide breaks down common urine drug test panels, lab abbreviations, and real examples so you can understand what your test form actually means.

What Do Drug Test Codes Mean?

Most urine test forms contain two types of identifiers:

Billing or Lab Codes

Numbers such as 2480 or 65304N are primarily laboratory billing codes.
They are used internally by labs and usually do not describe the substances tested.

Panel Abreveations

(Important Part) example: 35726N SAP9 w/nit

The abbreviations tell you:

• Number of drugs tested   
• Drug categories included
• Add-on testing
• Exclusions (such as NO THC)

These are the details you should focus on.

The Standard Urine Drug Test: 5-Panel

The most common workplace drug screen is the 5-panel urine test.

Standard 5-Panel Includes:

• AMP — Amphetamines
• COC — Cocaine
• THC — Marijuana (Cannabinoids)
• OPI — Natural Opiates (Heroin, Morphine, Codeine)
• PCP — Phencyclidine

This panel is widely used for employment screening and federal testing programs.

What Is a 4-Panel Drug Test?

A 4-panel test is NOT standardized — it can vary depending on employer or state rules.
most common in past few years is no THC ( look at state laws)
  NOTE  Standard test are 5 Panel so if it is a 4 panel THC would most likly be the missing one

Common 4-Panel Version
Version 1

• THC
• Cocaine
• Opiates
• Methamphetamine

Version 2

• AMP — Amphetamine
• BZD — Benzodiazepines
• COC — Cocaine
• THC — Marijuana

Version 3 (No THC States or Employers)

• Amphetamines
• Cocaine
• Opiates
• PCP

Some locations exclude marijuana testing entirely.

“NO THC” — What Does It Mean?

You may see labels such as:

• NO THC
• –THC
• XM (Exclude Marijuana)

This means marijuana is NOT included in the screening panel.
This is common in states or workplaces where THC testing is restricted or optional.

Understanding Drug Screen Panel Labels

Example:2480 – 7DSP/NO THC/PHN
Breakdown:

• 7DSP = 7 Drug Screen Panel
• NO THC = Marijuana excluded
• PHN = Additional amphetamine metabolite testing

PHN indicates screening for 4-hydroxynorephedrine, a metabolite used to confirm amphetamine results and reduce false positives.

Example:5111 – 9DSP/EXP OPI/NO THC/PPX/OXY/ECS/PHN
Meaning:

• 9DSP -- 9-panel test
• EXP OPI -- Extended opiate testing
• NO THC -- Marijuana excluded
  
• PPX -- Propoxyphene
• OXY -- Oxycodone testing added
• ECS -- Ecstasy (MDMA)
• PHN -- Expanded amphetamine confirmation
  

Extended Opiates Include:

• Oxycodone
• Hydrocodone
• Fentanyl (varies by panel)
• Other semi-synthetic opioids

Standard opiate panels only detect natural opiates like heroin, morphine, and codeine.

Add-On Validation Testing (SVT or TestSure)

Many modern tests include specimen integrity checks.
Example:
10SAP (-THC) + SVT
SVT = Specimen Validity Testing

These checks detect tampering or dilution.
SVT Measures:

• CR — Creatinine levels
• GL — Glutaraldehyde
• pH — Acid/alkaline balance
• NI — Nitrites
• OX — Oxidants
• SG — Specific gravity

These confirm the urine sample is genuine and unaltered. 
This is why you use Powdered synthetic urine like Fake It its undetectable 

E-Cup Tests (Point-of-Collection Testing)

E-Cups are rapid tests performed immediately at the collection site.
Example:
XCup4-4045 — 4 Panel (No THC)
Typical cutoffs:

• Amphetamines: 500/250 ng/mL
• Cocaine: 150/100 ng/mL
• Opiates: 2000 ng/mL
• PCP: 25 ng/mL

Results are screened instantly before lab confirmation.

Common Quest Diagnostics Panel Examples

Drug Monitoring, Panel 4, Screen, Urine (Test Code: 39419): A qualitative screening assay designed to detect the presence or absence of specific licit or illicit drugs, often used for therapeutic drug monitoring and treatment compliance.

Drug Toxicology Monitoring 4 with Confirmation, Urine (Test Code: 91484): A urine screen (immunoassay) paired with confirmation via mass spectrometry, targeting classes like amphetamines, barbiturates, benzodiazepines, cocaine, marijuana, and opiates.

38490n sap 4/2k-3+6a/dx + bup

4/2k -3+6A/OX+BUP:   

  4 panel extended opiate w 2000 cutoff
 -3+6A: * 3: Generally indicates the testing of three specific analytes (Amphetamines, Methamphetamines, and MDMA/Ecstasy). 

OX: Stands for Oxidants. This is a specimen validity test to check if the sample has been tampered with or "bleached" using oxidizing agents.
 BUP: Stands for Buprenorphine (commonly known by the brand name Suboxone). This panel specifically adds Buprenorphine to the standard list

9-Panel Tests codes

35726N SAP9 w/nit

• Standard 9 drugs
• Includes nitrate testing (detects adulterants)

8145 – 9DSP / EXP OPI / NOTHC / OXY / 6AM / PHN

Includes:

• Extended opioids
• Oxycodone
• Heroin metabolite testing 
• Amphetamine confirmation
• No THC screening

10-panel

Code 35765N (XM):

The 35765N Base: This is a 10-panel urine drug screen with confirmation.

• The (XM) Suffix: This indicates that Marijuana (THC) is excluded from the panel.
• The "N": As mentioned before, this is just a regional laboratory identifier (likely Northeast or North).

What is actually being tested?
Even though it excludes marijuana, it is a comprehensive test that screens for the following 9–10 drug classes:

1. Amphetamines (including Methamphetamine)
2. Barbiturates
3. Benzodiazepines
4. Cocaine Metabolites
5. Methadone
6. Methaqualone (Quaaludes)
7. Opiates (Codeine, Morphine)
   
8. Phencyclidine (PCP)
9. Propoxyphene
10. Specimen Validity (Checks for pH, Creatinine, and Nitrites to ensure the sample is "clean" and not diluted).

This checks for "oxidants" like nitrates or bleach to ensure the sample hasn't been tampered with or "cleansed."

DOT Drug Test Panels

Department of Transportation testing follows strict federal standards.
Example:
65304N — DOT Drug Panel w/TS
Tests for:

• Amphetamines
• Cocaine
• THC
• Natural opiates
• Semi-synthetic opioids
• Oxycodone/Oxymorphone
• PCP

Includes full specimen validation.

What Are Cutoff Levels?

Sometimes panels list numbers such as:
AMP500 / COC150
These are detection thresholds.
Example:

• Cocaine cutoff 300 ng/mL = standard
• Cocaine cutoff 150 ng/mL = more sensitive test

Lower cutoff = stricter detection.

Why Understanding Your Panel Matters

Knowing your exact panel helps you:

• Understand what substances are screened
• Avoid assumptions about THC testing
• Recognize extended opioid panels
• Interpret lab paperwork correctly
• Prepare properly for testing

Many people misunderstand their results simply because they never decoded the panel information.

Conclusion
Urine drug test forms may look complicated, but they follow predictable labeling rules. Once you understand panel numbers, abbreviations, and validation markers, you can quickly determine:

• What drugs are included
• Whether marijuana is tested
• How sensitive the test is
• Whether confirmation or tamper detection is used

Reading the abbreviations — not just the code number — gives you the real answer to “What am I being tested for?”
