A drug-test cup combines urine collection and screening in one device. A dip card is immersed in a urine specimen collected in a separate cup and is often easier to store. An oral-fluid test uses saliva and may fit programs that prefer an observed, non-urine collection process.

Compare urine test cups, dip cards, and oral-fluid tests. Always follow the specific product IFU.

Start with the substances your program needs to screen for, then compare specimen type, cutoff levels, panel configuration, regulatory status, and collection workflow. Do not choose only by the number of panels: two products with the same panel count may screen for different analytes.

For example, browse the full drug-testing collection or contact us with the exact substances your program requires.

Yes, selected configurations include specialized panels such as fentanyl (FEN), ethyl glucuronide/alcohol metabolite (ETG), synthetic cannabinoids (K2), and kratom (KRA). Availability varies by format and configuration.

Examples include the 14-panel ECO-II cup with ETG and fentanyl, the 19-panel MEGA ECO-II cup, and the 12-panel Oral Cube with fentanyl and K2.

Kay Scientific carries selected single-panel dip tests for programs that need to screen for one specific analyte. Browse the dip-card collection, including the single-panel fentanyl dip card. Confirm the analyte, cutoff, intended use, and regulatory status on the individual product page before ordering.

Yes, selected urine and oral-fluid configurations exclude THC. Because the remaining panel contents vary, review the full analyte list rather than relying on the panel count alone. See the 6-panel Oral Cube without THC or ask our team to compare no-THC options.

Not necessarily. Panel count alone does not confirm that fentanyl is included, and two 10-panel or 12-panel products can screen for different substances. Look for fentanyl or FEN in the exact analyte list and confirm the cutoff and specimen type before ordering.

Browse current drug-test configurations or send Kay Scientific your required analyte list for a product match.

Fentanyl and norfentanyl are related but not identical targets: norfentanyl is a primary metabolite of fentanyl. Devices may be designed around different target compounds and cutoff levels, so an FEN and NFEN product should not be assumed interchangeable. Confirm the target and cutoff in the manufacturer IFU and match it to your program requirements.

Ask Kay Scientific to compare fentanyl-testing options.

Result rules are device-specific. On many competitive immunoassay drug screens, a visible test line—even a faint one—may be interpreted as negative when the control is valid, but you must follow the IFU supplied with that exact device. Read the result only within the manufacturer’s stated time window and never apply another brand’s instructions.

The required specimen amount varies by device. Urine cups have minimum fill requirements, dip cards require enough specimen to reach the indicated immersion level without exceeding it, and oral-fluid collectors use a product-specific collection indicator or procedure. Check the exact IFU before collection.

If specimen volume is an important workflow constraint, tell our team which format you use.

Do not assume that a point-of-care or instant drug test satisfies DOT testing requirements. Federally regulated transportation testing follows the U.S. Department of Transportation’s procedures in 49 CFR Part 40, including required specimen, laboratory, medical-review, and reporting processes. Use an instant device only when your applicable program and legal requirements allow it.

Review the official DOT Part 40 procedures and consult your program administrator or compliance adviser.

Yes. Send the current brand, product name or SKU, specimen type, complete analyte list, cutoffs, box quantity, regulatory status, and estimated order volume. A photo of the box or product insert is also helpful. Kay Scientific can identify the closest available match and explain any meaningful differences before you switch.

Request a product comparison.

Adulterant indicators are designed to help identify certain specimen characteristics that may be inconsistent with an unaltered urine specimen. The included indicators and interpretation ranges vary by product. Review the product page and manufacturer IFU for the exact checks and limitations.

The 19-panel MEGA ECO-II cup is one available configuration that includes adulterant checks.

Yes. Options include selected oral-fluid configurations with alcohol and ETG urine dip tests. These products screen different markers and use different specimen types, so review the intended use, cutoff, timing, and IFU for the specific device. Browse oral-fluid testing products or the single-panel ETG dip card.

Current offerings may include COVID-19 antigen, Influenza A/B, combination COVID-19 and Flu A/B, RSV, and Strep A rapid tests. Inventory and regulatory status vary by product.

Browse the current rapid health-test collection for available products and product-specific details.

Yes. Kay Scientific carries combination products designed to detect and differentiate SARS-CoV-2, Influenza A, and Influenza B from one collected specimen, as specified by the manufacturer. Examples include the Status COVID-19/Flu A&B Test and the Rapid Check COVID-19/Flu A&B Test.

Compare specimen type, workflow, result time, box quantity, and current regulatory labeling before selecting a product.

The better fit depends on the targets your clinic needs, patient workflow, seasonality, specimen type, testing volume, and product instructions. A combination test may simplify testing when COVID-19 and influenza differentiation is needed; separate tests may be appropriate when only one target is required.

Review the current respiratory options or ask us to compare products side by side.

Kay Scientific carries professional rapid-test options for Strep A and RSV. Product eligibility, specimen type, intended use, and regulatory status are specific to each device. Review the Rapid Strep A Antigen Test and the available products in the health-test collection.

A professional-use test is labeled for use in an authorized professional testing setting and may require specific training, certification, or CLIA considerations. An over-the-counter test is labeled for consumer self-testing under its instructions. The designation must be verified on the individual product page and manufacturer labeling; it should never be assumed from the product name alone.

See Kay Scientific’s FDA and regulatory disclaimer.

Result time varies by product and must be taken from the specific manufacturer IFU. Many rapid antigen tests are designed to provide results during the visit, but the correct read window is essential; reading too early or too late can produce an invalid interpretation.

Open the individual listing in the rapid health-test collection to compare current options.

Specimen requirements differ by device and may include anterior nasal, nasopharyngeal, or throat swabs. A swab type or collection method approved for one product should not be substituted for another. Confirm the intended specimen, included components, collection steps, and patient-age limitations in the exact IFU.

Box quantity varies by brand and product. Compare both the number of tests per box and price per test, then confirm which collection materials are included. The individual Kay Scientific product page lists the sales unit and available quantity pricing.

Browse respiratory tests or request a quote for your expected monthly volume.

Use the performance section of the manufacturer’s current package insert or IFU for that exact product. Performance measures can vary by target, comparator method, population, specimen type, and study conditions, so figures from one rapid test should not be applied to another.

Check the document links on the product page or request the current insert using the product name or SKU.

That depends on the intended-use statement and age range in the exact product labeling. Pediatric practices should verify specimen type, patient population, collection procedure, regulatory status, and any requirements for follow-up testing before purchasing. Kay Scientific can provide product documentation, but clinical testing decisions belong to the qualified healthcare professional.

Ask for an RSV product comparison.

A negative rapid result does not always rule out infection. Follow the specific IFU, current public-health or clinical guidance, patient presentation, and your organization’s protocol for repeat, confirmatory, or molecular testing. Kay Scientific supplies products and documentation but does not diagnose patients or replace clinical judgment.

For at-home COVID-19 antigen testing, the FDA provides current guidance on reducing false-negative risk.

Include the test targets needed, preferred brand or current product, expected boxes per order, ordering frequency, shipping ZIP code, and whether you need a professional-use or CLIA-waived option. This lets the team compare the closest available configuration and shipping plan.

Request clinic pricing.

Employers and staffing agencies commonly compare urine cups, dip cards, and oral-fluid devices based on observed collection needs, panel requirements, testing volume, storage, and internal policy. Kay Scientific can help compare products, but the buyer remains responsible for ensuring the selected testing program follows applicable laws and workplace requirements.

Start with drug-testing products or speak with a specialist.

Consider the substances your program needs to screen, specimen type, collection workflow, confirmatory-testing policy, expected volume, and whether specialized panels such as fentanyl, ETG, K2, or kratom are needed. Higher panel counts do not automatically mean a better fit; the exact analyte list matters.

See the 19-panel MEGA ECO-II cup or request a comparison based on your current product.

Yes. Kay Scientific supports nonprofit organizations, shelters, rescue missions, and community programs with product guidance, competitive pricing, and ordering assistance. Share your required configuration, budget, quantity, and delivery timeline so the team can recommend available options.

Request organization pricing.

Yes. For recurring or multi-location needs, provide the product, estimated quantity, ordering schedule, and destination ZIP codes. The team can review inventory planning, shipping options, and customized pricing based on the full requirement.

Discuss recurring or multi-location ordering.

Yes. Many product pages display quantity-based discounts, and customized pricing may be available based on product, box quantity, ordering frequency, and shipping requirements. For larger or recurring purchases, request a quote rather than assuming the single-box online price is the final available price.

Request volume pricing.

Yes. If you find a lower price for a comparable product, send the product configuration, brand, quantity, shipping terms, and current availability. Kay Scientific will review the comparison and provide the most competitive option available. Products must be comparable; panel contents and box quantities can differ even when product names sound similar.

Send us your current product and pricing.

Box quantities vary. Dividing the box price by the number of tests provides a clearer comparison, but also account for shipping, panel configuration, included collection components, expiration dates, and regulatory status. Selected Kay Scientific product pages display both box pricing and price per test.

Storage temperature, humidity limitations, light protection, and whether a product may be refrigerated vary by device. Follow the storage conditions printed on the box and in the current IFU. Do not freeze a product unless its labeling explicitly permits it, and allow any required equilibration time before use.

Contact Kay Scientific with the product name and lot if you need help locating its storage instructions.

Shelf life is product- and lot-specific, and remaining dating can change as inventory rotates. If your program has a minimum dating requirement—especially for a large, seasonal, or low-volume purchase—contact Kay Scientific before ordering so the team can confirm current lot availability when possible.

Ask about current expiration dating.

Samples or smaller trial quantities may be available for selected products, depending on manufacturer programs and inventory. Tell Kay Scientific the product, intended testing setting, estimated future volume, and what you need to evaluate. Availability is not guaranteed.

Ask about a sample or trial order.

Business purchasing options depend on account approval, order details, and Kay Scientific’s current terms. Send your organization name, billing and shipping information, requested products, quantities, and required timeline. The team will confirm whether a purchase order or account terms can be accommodated before the order is released.

Contact the team about business purchasing.

Yes. Organizations can contact Kay Scientific for commonly requested vendor information and account setup assistance. If your purchase is tax exempt, provide valid exemption documentation before ordering or as directed by the team; eligibility and documentation requirements vary by jurisdiction.

Request vendor-onboarding assistance.

Many product pages include downloadable instructions or brochures. Other documentation—such as safety data sheets or manufacturer certificates—depends on the product and what the manufacturer makes available. For lot-specific or expiration information, send the product name, SKU, quantity, and the document your organization requires.

Request product documentation.

Kay Scientific can review recurring demand, ordering frequency, preferred products, acceptable substitutes, and destination locations to help plan replenishment. Inventory cannot be guaranteed without a confirmed arrangement, so programs with critical timelines should discuss forecasts and alternatives before stock becomes low.

Discuss recurring inventory needs.

Individuals may purchase products when the specific item is legally offered and appropriate for the intended use, but a professional-use product should not be treated as an at-home test. Before ordering, verify that the listing and manufacturer labeling identify the product for over-the-counter or home use and follow all instructions.

If you are unsure, ask Kay Scientific to confirm the product designation before purchasing.

We ship in-stock orders the same business day when placed before 2 PM PT. Processing times may vary based on the destination and shipping method selected.

Have a time-sensitive order? Contact our team to confirm availability and delivery options.

Yes. Available services depend on destination, order time, inventory, and carrier availability. Contact Kay Scientific before placing a time-sensitive order so the team can confirm stock and available delivery methods. An expedited shipping method changes transit speed; it does not override product availability or processing requirements.

Kay Scientific ships within the United States and may serve U.S. territories according to the current shipping policy and available carrier services. Review the shipping policy or contact the team with the destination ZIP code for confirmation.

Product pages show current storefront availability, but time-sensitive or high-quantity orders should be confirmed directly because inventory can change. Send the product name or SKU and requested quantity through the contact and quote form.

Return eligibility, timing, fees, and final-sale exclusions are governed by the current policy and may vary by product condition or category. Review the return and refund policy before sending anything back. Contact Kay Scientific for authorization and instructions before returning an order.

CLIA-waived status applies to specific tests and intended-use conditions. It does not mean every product in a category is waived or that every setting may use it without requirements. Verify the exact product’s current labeling, manufacturer IFU, and applicable testing-site obligations before use.

Kay Scientific identifies CLIA-waived products where applicable; see the individual listing and regulatory disclaimer.

No. Regulatory status varies by product. A product may be FDA cleared, FDA authorized, CLIA waived, intended for over-the-counter use, intended for professional use, or labeled Forensic Use Only. Availability on the website does not by itself establish any particular status.

Confirm the exact listing and manufacturer labeling, and read the FDA and regulatory disclaimer.

A rapid drug screen provides a preliminary qualitative result. A non-negative or preliminary positive result may require confirmation using an appropriate laboratory method, such as GC/MS or LC/MS, according to the product labeling, your program protocol, and applicable requirements. Do not treat a screening result as a final laboratory-confirmed result.

Interpretation varies by device. Many competitive immunoassay drug screens use the presence or absence of control and test lines in a way that may feel counterintuitive, while respiratory tests can follow a different pattern. Always use the instructions supplied for that exact product and read results only within the stated time window.

Never apply instructions from a similar-looking product to a different device.

Detection windows are not fixed and can vary based on the substance, specimen type, cutoff, individual factors, timing, and other conditions. Cutoff levels are product-specific. Review the product page and manufacturer IFU, and do not use a general detection-window chart as a substitute for the device documentation or professional guidance.

Many Kay Scientific product pages include downloadable brochures, product inserts, or instructions beneath the ordering information. Open the individual product page and look for the document links. If a document is not listed, contact the team with the product name or SKU.
