How to Tell What Your Urine Drug Test is for

Urine Drug Test: What Am I Being Tested For?

Drug testing 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.

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.

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.

SAP (Substance Abuse Professional)

A SAP (Substance Abuse Panel) drug test is not a traditional drug screen, but a mandatory evaluation for employees (often DOT-regulated) who have failed or refused a drug test. It is a legally required process to evaluate the employee and determine the education or treatment needed before returning to safety-sensitive duties.

DSP (Drug screen Panel)

A DSP Drug Screen Panel. It is a rapid, preliminary test used to detect the presence of specific drugs or their metabolites in a biological sample, most commonly urine—typically a 4 or 5-panel urine test—before being hired, which often includes testing for marijuana (THC)

Screening (DSP) vs. Confirmation: A DSP is a preliminary screening. If it is positive, it is often sent for a more precise, second test called a confirmation test (GC/MS).

Add-On Validation Testing (SVT or TestSure)

Many modern tests include specimen integrity checks.

10SAP (-THC) + SVT

Example:10SAP (-THC) + SVT 
10 panel      
NO THC  
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 

"W/TS" stands for "Test Sure" Specimen Validation .

What "w/TS" Means

• Specimen Validity Testing: TS checks the urine sample for adulterants like nitrites, pH, and creatinine levels to ensure the specimen is not diluted or altered.
• Goal: To detect attempts to manipulate the drug test

NO THC Indicators

You may see abbreviations  such as:

XM

XM "exclude marijuana" drug test

NOTHC

self explanatory NO  THC 

-THC

Minus THC     -     this is also most 4 panel screens

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

FED (Federal Guidelines)

FED (Federal Guidelines)
This indicates that the test follows federal workplace drug testing guidelines, which are often used for pre-employment, reasonable suspicion, or high-safety positions.

The Standard Urine Drug Test: 5-Panel

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

Standard 5-Panel Includes:

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

AMP — Amphetamines

COC — Cocaine

THC — Marijuana (Cannabinoids)

OPI — Natural Opiates (Heroin, Morphine, Codeine)

PCP — Phencyclidine Phn

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.

Breakdown of Urine Drug Screen Panel Abbreviations

What is Phn on a drug test ?

Phencyclidine (PHN/PCP): Tests for the dissociative drug PCP.

   NOTE: confusing bad info may mention opioid  such as   Propoxyphene: true abreviation is PPX , or list   a minor   Amphetamine P-Hydroxynorephedrine:  which correct abbreviation is    HNE

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

example:
9DSP/EXOPI/NOTHC/PPX/OXY/ECS/PHN

The abbreviations tell you: 

• Drug categories included

• Number of drugs tested   
• Exclusions (such as NO THC)
• Add-on testing - Phencyclidine (PHN/PCP): Tests for the dissociative drug PCP
  

2480 – 7DSP/NO THC/PHN

PHN = Additional amphetamine metabolite testing

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

• 7DSP = 7 Drug Screen Panel
• NO THC = Marijuana excluded
• PHN =  Phencyclidine   PCP. 
  

Understanding Drug Screen Panel Abbreviations

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)

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)

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.

Breakdown of Quest lab code

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

Substance Abuse Panel

• 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."

10SAP FED (-THC) +SVT

drug test is a 10-panel, federal-guideline-based urine test that screens for commonly abused substances but specifically excludes testing for marijuana (THC), combined with a check to ensure the sample is valid

DOT Drug Test Panels

Department of Transportation testing follows strict federal standards.
The 65304N DOT Drug Panel w/TS is a standard urine drug test conducted by Quest Diagnostics for safety-sensitive employees regulated by the Department of Transportation (DOT). It is a 5-panel test that includes Test Sure (TS), a specimen validity testing process that checks for adulterants, substitution, or dilution

65304N — DOT Drug Panel w/TS

Example:65304N — DOT Drug Panel w/TS
The DOT 5-panel test screens for five specific drug classes (including various metabolites): 

• Opioids (codeine, morphine, heroin, hydrocodone, hydromorphone, oxycodone, and oxymorphone)
• Phencyclidine (PCP)

• Marijuana (THC) metabolites
• Cocaine metabolites (Benzoylecgonine)
• Amphetamines (including methamphetamine and MDMA)

• 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.
