Choose an 18 Panel Cup by Its Configuration

An 18-panel label describes the screening configuration. It does not tell you whether a particular cup includes gabapentin, xylazine, K2, kratom or specimen-validity indicators. Those details belong to the individual product.

Start with the substances your program needs to screen, then compare the available cups. A useful comparison includes the full panel list, cutoff levels, intended-use designation and collection format. Buying by panel count alone can leave a required target out of the order.

Compare Economy and Serenity Options

Product Format Main comparison point
Economy cup with K2, kratom and tramadol 90 mL cup Compact configuration with K2 and kratom among its listed panels.
Economy kit with specimen-validity indicators 90 mL cup pH, specific gravity and creatinine indicators alongside its drug-screening configuration.
Serenity drug screen with ADLTX 120 mL cup Serenity format with specimen-validity indicators.
Serenity cup with gabapentin and ADLTX 120 mL cup Dedicated gabapentin panel plus pH, specific gravity and creatinine indicators.
Serenity cup with EtG, fentanyl and ketamine 120 mL cup TCA and two THC screening thresholds distinguish this configuration.
Serenity cup with xylazine and kratom 120 mL cup Dedicated xylazine panel alongside kratom, ketamine and other listed targets.

Capacity is the size of the collection cup. Follow the product instructions for the amount of specimen required. A 120 mL capacity does not mean that the cup must be filled with 120 mL of urine.

What to Check Before Ordering

  1. Required panels: compare every requested drug or drug class with the exact product configuration.
  2. Cutoff levels: check the concentration and units for each panel. The same abbreviation can appear at different screening thresholds.
  3. Specimen-validity features: confirm whether pH, specific gravity and creatinine indicators are included.
  4. Intended use: use the designation on the exact device and its current instructions.
  5. Order details: select the quantity and review current pricing, availability and shipping options.

Drug Panels and ADLTX Indicators Serve Different Purposes

Drug-screening panels evaluate the targets listed for the cup. ADLTX indicators provide information about selected specimen characteristics. They are counted separately from the drug panels, and an unusual indicator result does not independently establish intentional tampering.

Our guide to specimen-validity indicators explains pH, specific gravity and creatinine, including how their color-pad readings differ from drug-panel results.

Match the Cup to the Intended Use

Panel count does not establish FDA clearance, CLIA-waived status or suitability for a particular testing program. For products labeled Forensic Use Only, follow the restrictions on the exact package and insert. Review our Forensic Use Only and intended-use notice when selecting a configuration.

Rapid screening results are preliminary. Follow the applicable program's procedure for review and laboratory confirmation of non-negative results. General website guidance does not replace the instructions supplied with the device.

Ordering 18 Panel Drug Test Cups in Quantity

For a repeat order, use the product SKU as well as the name. This helps keep the same configuration on subsequent purchases, especially when two cups have similar titles.

Compare the current quantity tiers on the product page. For a larger order, contact DrugTestingCup with the SKU, number of cups and delivery requirements. Our bulk purchasing guide covers useful questions about ordering and inventory planning.

If your required panel list is shorter, compare the 12 panel drug test cup collection. You can also browse all drug screen cups to find a configuration that matches the targets and intended use you need.

Frequently Asked Questions

Do all 18 panel drug test cups screen for the same substances?

No. The configuration varies by product. Compare the full list of panels and cutoff levels on the exact cup rather than assuming that every 18-panel device is interchangeable.

Does every 18 panel cup include gabapentin or xylazine?

No. Choose a configuration that specifically lists the required panel. Gabapentin and xylazine are separate targets and should not be inferred from the overall panel count.

Do adulterant indicators add to the drug-panel count?

No. pH, specific gravity and creatinine indicators evaluate specimen characteristics. They are separate from the drug-screening panels.

Does a 120 mL cup require a 120 mL specimen?

Cup capacity and the required specimen volume are different specifications. Follow the minimum collection amount stated in the instructions for the exact device.

How should I compare prices for bulk orders?

Compare the price per cup at the same order quantity, the exact SKU and configuration, current availability, and applicable shipping charges or offers.
