About this item

As empowerDX states it

  • How it measures: Passive radon sampler, laboratory analysis
  • Exposure time: 48 hours to 96 hours
  • Lab fee: Included in the kit
  • Power: None needed

The empowerDX Standard Radon Test is a short-term, mail-in radon test: you leave one passive sampler on the lowest level of your home suitable for occupancy for 48 to 96 hours, then ship it to empowerDX's laboratory, which emails the result. empowerDX says the price covers outbound shipping and the laboratory analysis but not the return postage, and that results come 3 to 5 business days after the lab receives the sample. Its product text does not name the laboratory; the return address and sampler pouch in its kit photo point to Alpha Energy Labs of Carrollton, Texas, which the National Radon Safety Board's June 2026 list includes among the laboratories it accredits.

What you get

empowerDX says each kit comes with everything you need, including clear instructions and a professional-grade radon sampler. Its kit-contents photo shows four items: the kit box, an instructions-for-use booklet, the sampler in its pouch, and a shipping envelope for the return. There is no prepaid return label in the Standard kit; empowerDX says you return the sample in a box or package, or by applying postage directly to the return shipper, with any carrier you choose.

How it works

In our words, from the maker's documents

This is a passive test. empowerDX gives the collection method as a passive radon sampler, and nothing in the kit needs power or shows a number: you place the sampler, leave it for the exposure period, record the start and stop times and ship it back, and the laboratory works out the radon level afterwards. The EPA describes passive devices the same way: they do not need power to function, are exposed to the air in the home for a set period, and are then sent to a laboratory for analysis.

empowerDX's product text does not say what the sampler contains. The kit-contents photo on its product page does: the sampler's pouch is printed "eurofins RADON SAMPLER" and "CONTENTS: ACTIVATED CHARCOAL". Charcoal canisters are among the passive detectors the EPA says are most commonly used for short-term testing, alongside charcoal liquid scintillation devices, alpha track detectors and electret ion chambers.

The analysis is part of the price. empowerDX is the trade name of DNA Diagnostics Center, Inc., a home lab-testing company that its about page describes as a wholly owned subsidiary of Eurofins Scientific. It sells this kit among its home safety tests, next to water tests, and says its home testing is available in all 50 states. In the text of its product page, empowerDX does not name the laboratory that analyzes the sampler: it calls it "our lab" and describes it as certified by the National Radon Proficiency Program (NRPP).

A two-to-four-day test is a snapshot. The EPA says short-term tests remain in a home for two days to 90 days, depending on the device, that radon levels tend to vary from day to day and season to season, and that a long-term test, more than 90 days, is more likely than a short-term test to tell you a home's year-round average. This kit sits at the short end of that range: it tells you whether a home needs a closer look, not what its average is over a year.

The result comes back as a report, not a reading on a screen. empowerDX says Standard results are typically emailed within 3 to 5 business days after the lab receives the sample, and calls that an estimate. Its Express Radon Test uses the same testing method and gives the same type of result; the difference is the prepaid return and a faster turnaround, within 1 business day after the lab receives the sample.

Independent evidence

Who checks a device like this

C-NRPP's consumer evaluation covers electronic monitors, not laboratory-analyzed test kits, so it has no result for empowerDX Standard Radon Test. A kit's result comes from the laboratory that analyzes it. Where the maker names that laboratory, or the page cites the National Radon Safety Board's lists of approved devices and accredited laboratories for it, the “How it works” panel and “Questions people ask” say so.

NRSB lists
NRSB's Accredited Radon Laboratories list (June 2026) includes Eurofins Environment Testing Radon LLC d/b/a Alpha Energy Labs, Carrollton, TX, 25ARL003, accredited for 10325 Alpha Energy Labs Tray RD1 (AC), ARL expiration 07/30/2027; NRSB's approved device list (July 2026) includes 10325 Alpha Energy Labs Tray RD1. empowerDX's text names no laboratory or device. The return envelope in its kit-contents photo is addressed to 2501 Mayes Road Ste 100, Carrollton TX 75006, and the sampler pouch reads "Manufactured by Alpha Energy Laboratories", so this records the laboratory the printed return address points to, not a confirmed match. Checked October 8, 2026.

What is in the box

empowerDX says each kit comes with everything you need, including clear instructions and a professional-grade radon sampler. Its kit-contents photo shows four items: the kit box, an instructions-for-use booklet, the sampler in its pouch, and a shipping envelope for the return. There is no prepaid return label in the Standard kit; empowerDX says you return the sample in a box or package, or by applying postage directly to the return shipper, with any carrier you choose.

empowerDX publishes no model number for the kit. Its terms of service give products bought on its own site a one-year limited warranty against defects in materials and workmanship, extending only to the original purchaser from that site. For a kit bought at Amazon or another authorized retailer, the terms send refund and cancellation questions to the place of purchase, and they say empowerDX cannot accept returned or unused kits.

What it costs to run

The kit is used once. By empowerDX's statement, the laboratory analysis and the shipping to you are in the price, and the return shipment is yours to pay, by any carrier. New Jersey residents also pay a state-mandated laboratory fee at test registration, which empowerDX says is set by the state of New Jersey and applies to both its Standard and Express kits.

A faster result costs more. empowerDX's Express Radon Test adds a prepaid FedEx return envelope and results within 1 business day after the lab receives the sample, usually the same day when it arrives by 10 a.m.; the exposure is the same 48 to 96 hours.

Two other costs are worth planning for. empowerDX's terms ask you to use the kit within 60 days to avoid an expired kit, say samples that reach the lab after the expiration date on the outside of the kit will not be processed, and say an expired kit is not replaced. And a high first result means another test: the EPA says to take a follow-up test when a first short-term result is 4 pCi/L or more, and its side-by-side option for a home sale takes two short-term tests at the same time in the same place, which with this kit means two kits.

Fit and setup

Who it fits, and how to use it

The fit, then setup and placement as the guidance asks

Who it fits

Good fit if, and look elsewhere if

Good fit if

  • You want a first, short-term screening test with the laboratory analysis and the shipping to you in the kit price.
  • You can keep windows and outside doors closed for two to four days and the 12 hours before.
  • You are comfortable registering the kit online and getting the result by email.
  • You are happy to choose your own carrier and pay for the return shipment.
  • You can ship on a weekday soon after the test ends, so the sample reaches the lab within 10 days.

Look elsewhere if

  • You want return postage included; empowerDX's Express kit has a prepaid FedEx envelope, and some other kits include a prepaid mailer.
  • You want a year-round average; the EPA counts tests of more than 90 days as long-term.
  • You want the analyzing laboratory named in the maker's product text before you buy.
  • You need a test for a home sale; check your state's rules, which may call for a licensed or certified tester.
  • You want two samplers from one box for a side-by-side test; the Standard kit holds one sampler.

Setup and placement

4 steps

  1. empowerDX's placement rule is short: put the sampler in a central room on the lowest level of your home suitable for occupancy, finished or unfinished, and leave it exposed for 48 to 96 hours (2 to 4 days). Record the start and stop times, then ship it as soon as the test ends. empowerDX says the sample must arrive at its laboratory within 10 days of the stop date to remain valid, and its three-step outline has you mail it to the lab Monday to Friday.
  2. The pouch in empowerDX's kit-contents photo carries two handling rules of its own: do not remove, tear or puncture the paper, and keep the printed side facing upward during testing. Follow the instructions that come in your box; empowerDX says each kit includes them.
  3. Closed-house conditions matter for a test this short. The EPA says that for a short-term test of 2 to 4 days you should keep closed-house conditions for at least 12 hours before the test begins and for the whole test: windows closed, outside doors closed except for normal entry and exit. Heating and air-conditioning fans that re-circulate air may run, but not fans or other machines that bring in air from outside. The EPA also says not to run short-term tests lasting less than four days during severe storms or periods of high winds.
  4. For the spot in the room, the EPA's general guidance fills in what empowerDX leaves out: the lowest lived-in level of the home, in a room used regularly but not the kitchen or bathroom, at least 20 inches above the floor, and away from drafts, high heat, high humidity and exterior walls. Do not disturb the sampler at any time during the test.

6 questions about the empowerDX Standard Radon Test, answered

Asked about the Standard Radon Test

Which laboratory analyzes the empowerDX Standard Radon Test?

empowerDX does not name it in the text of its product page; it refers to "our lab" and describes it as certified by the National Radon Proficiency Program (NRPP). Its about page says empowerDX is a wholly owned subsidiary of Eurofins Scientific.

The kit-contents photo on the same page shows printed names. The sampler pouch reads "eurofins RADON SAMPLER" and "Manufactured by Alpha Energy Laboratories", and the instruction booklet's cover says the kit is "Powered by Alpha Energy Laboratories, a division of Eurofins". Those lines are quoted as printed in empowerDX's photo; check the instructions in your own box for where to ship.

The return envelope in the same photo is addressed to 2501 Mayes Road, Carrollton, Texas. The National Radon Safety Board's Accredited Radon Laboratories list, June 2026, includes Eurofins Environment Testing Radon LLC d/b/a Alpha Energy Labs of Carrollton, Texas, laboratory 25ARL003, accredited through July 30, 2027 for one device, 10325, the Alpha Energy Labs Tray RD1. NRSB's July 2026 list of approved devices includes that device under method AC, which NRSB's device definitions spell out as activated charcoal adsorption. empowerDX's text does not name its laboratory or its device, so this records the laboratory the printed return address points to, not a confirmed match.

How long should the sampler stay out?

empowerDX recommends 48 to 96 hours (2 to 4 days) and says samplers exposed less than 2 days or more than 7 days are invalid. The two statements leave a gap: five to seven days falls outside the recommended window but inside the valid one, so plan for two to four days and treat the longer limit as a margin, not a target. The EPA's minimum for any radon test is 48 hours.

When do results arrive, and how?

empowerDX says Standard results are typically emailed within 3 to 5 business days after the lab receives the sample, and calls the figure an estimate. The return trip comes on top: with no prepaid label, its length depends on the carrier you choose, and the sample must reach the lab within 10 days of the stop date.

Is the lab fee included?

Yes, except New Jersey's state fee. empowerDX says the cost includes outbound shipping and laboratory analysis, and that New Jersey residents pay a state-mandated laboratory fee at test registration. The return postage is not included in the Standard kit.

Can I use it for a home sale?

empowerDX describes the kit as suited to standard real estate transactions; that is the maker's description. The EPA's Home Buyer's and Seller's Guide recommends three short-term testing options for sales, one of them two short-term tests at the same time in the same location for at least 48 hours, and says any real estate test should include steps to prevent or detect interference with the test device. It also notes that many states require radon professionals to be licensed, certified, or registered. Check your state's rules before relying on a do-it-yourself kit.

What should I do with the result?

Follow the EPA's steps. If a first short-term result is 4 pCi/L or more, take a follow-up test, either a long-term test or a second short-term test; if the first result is more than twice the 4 pCi/L action level, the EPA says to take the second short-term test immediately. Consider fixing the home if the average of the first and second test is 4 pCi/L or more, and fix it if a long-term follow-up is 4 pCi/L or more. The EPA also suggests considering a fix between 2 and 4 pCi/L.
