Quick answer: A 5-panel urine drug test needs enough urine to reach the cup's fill line, typically 30 mL or more. DOT-regulated collections require at least 45 mL, split 30 mL and 15 mL, under 49 CFR Part 40. The panel detects THC, cocaine, opiates, amphetamines and PCP. American Screening Corp supplies FDA-cleared, CLIA-waived cups.
- Fill to the line printed on the device; the package insert for your specific cup is the final word on volume.
- DOT split-specimen collections are a separate process with a 45 mL minimum.
- Every positive screen is preliminary; confirm by GC/MS or LC-MS/MS laboratory testing.
How much urine does a 5-panel test need?
Most instant 5-panel cups work when the donor fills the cup to the marked fill line. For many devices that is roughly 30 mL, but volume varies by manufacturer, so always read the package insert for the lot you are using.

A dip card needs less volume than a cup. The collector fills a clean container, then holds the strip in the urine to the dip line for the time the insert specifies, without letting the urine pass the arrow.
Our drug test cups and drug test dip cards both ship with printed fill and dip lines and a package insert.
What does a 5-panel test detect, and at what cutoff?
A 5-panel urine test screens for five drug classes. The HHS Mandatory Guidelines for Federal Workplace Drug Testing Programs (urine), published by SAMHSA, set the federal initial-test cutoffs shown below. Non-regulated cups may use different cutoffs, so confirm them on the insert.
| Drug class | Federal initial cutoff (ng/mL) | Typical detection window |
|---|---|---|
| Marijuana metabolite (THCA) | 50 | 1-3 days occasional use; longer with heavy use |
| Cocaine metabolite (benzoylecgonine) | 150 | 2-3 days |
| Opiates (codeine/morphine) | 2,000 | 1-3 days |
| Amphetamines (amphetamine/methamphetamine) | 500 | 2-3 days |
| Phencyclidine (PCP) | 25 | 3-8 days |
Detection windows are general ranges. Dose, frequency, metabolism and hydration change them for each person.
What volume does a DOT collection require?
Under 49 CFR Part 40, a DOT urine collection uses a split specimen. The collector pours at least 30 mL into the primary bottle and 15 mL into the split bottle, so the minimum is 45 mL. DOT collections go to a certified laboratory and are not decided by an instant cup.
The collector must also check the temperature of the specimen within four minutes. The acceptable range in Part 40 is 90 to 100 degrees F (32 to 38 degrees C). Employers with DOT-covered drivers should follow the rule text, not a product insert.
What if the donor cannot give enough urine?
A short sample is common, and it should be handled by procedure, not by guesswork. For non-regulated testing, set a written policy before the first collection.
- Keep the donor in the collection area and let them drink a reasonable amount of fluid.
- Do not combine specimens or top up a partial sample.
- Offer another attempt after a set time, as your written policy states.
- Record the attempts and the outcome on the collection form.
- For DOT collections, follow the shy bladder procedure in 49 CFR Part 40 and refer medical questions to a qualified professional.
Collection checklist for clinics, courts and employers
- Confirm the cup lot, expiration date and the cutoffs printed on the label.
- Have the donor wash hands and empty pockets as your policy requires.
- Check that the cup shows a valid temperature strip reading when the cup has one.
- Fill to the marked line; do not overfill.
- Read results within the window in the insert, usually a few minutes, and do not read after the time limit.
- Treat a non-negative result as preliminary and send a specimen for GC/MS or LC-MS/MS confirmation.
- Document chain of custody for any specimen that may be confirmed or used in a decision.
Why does the fill line matter for accuracy?
Too little urine can leave part of the test area uncovered, which can produce an invalid line or a late read. Too much can flood the device. A clean, correctly filled cup gives a readable result and fewer repeat collections, which saves staff time at volume.

Frequently asked questions
How much urine is needed for a 5-panel drug test?
Most instant cups need urine up to the fill line, typically 30 mL or more. DOT collections require 45 mL. Check the insert for your device.
Can a 5-panel test work with a small sample?
Only if the sample reaches the fill or dip line the insert requires. A short sample should not be topped up or combined; recollect under your written policy.
What does a 5-panel urine test detect?
It screens for THC, cocaine, opiates, amphetamines and PCP at the cutoffs on the device. A positive screen is preliminary and needs GC/MS or LC-MS/MS confirmation.
Is the volume the same for a DOT test?
No. DOT collections follow 49 CFR Part 40 and require at least 45 mL, split into 30 mL and 15 mL bottles, and are sent to a certified laboratory.
