Sensa vs Everlywell: Lab hs-CRP by Mail or Saliva CRP in 15 Minutes

One thing to say up front: this comparison lives on the Sensa Wellness site, and Sensa is our product. We checked Everlywell's product and how-it-works pages on October 27, 2026, and we have tried to write the version of this article that is actually useful, which means naming the situations where Everlywell is the better choice.

The whole comparison comes down to one distinction. Everlywell is at-home sample collection for a laboratory test. Sensa is an at-home test. The wait, the cost, and the kind of number you get back all follow from that difference.

What Each Test Measures and How

Everlywell measures hs-CRP and vitamin D in blood. According to Everlywell's website, the Vitamin D & Inflammation Test reports high-sensitivity C-reactive protein (hs-CRP) and 25-hydroxy vitamin D from a finger-prick sample. Your dried blood spot goes to a CLIA-certified laboratory, where an hs-CRP immunoassay quantifies the protein in milligrams per liter, including the low levels a standard CRP test cannot resolve. If the distinction between the two assays is new to you, our explainer on hs-CRP versus standard CRP covers it.

Sensa measures CRP in saliva and reports a score. You spit into the vial, the reagent inside changes color in response to the CRP present, and you scan the vial with the Sensa app. The app converts that color change into an inflammation score from 0 to 100 and places it in one of three tiers: In range, Worth watching, or Time to reset. This score is not an hs-CRP value. Saliva CRP and blood hs-CRP are different fluids measured on different scales, and a Sensa score should never be read against blood reference ranges or cardiac risk categories. Sensa is a general wellness product, and its value lies in repeated readings that show direction over time.

What the difference means in practice. A lab hs-CRP value speaks the language your doctor uses. A Sensa score speaks the language of trends: is this week higher or lower than last week, and what changed in between? Neither replaces the other, which is why the rest of this article treats them as two tools rather than two versions of the same tool.

The Experience, Step by Step

Everlywell, from order to result. You order the kit online, and Everlywell says it usually arrives within three to five business days. You register the kit's unique ID on their site, then use the included lancet to prick a fingertip and drop blood onto the designated spots on the collection card. Once the card is dry, you pack it in the return mailer with the prepaid shipping label and drop it in the mail. The lab processes the sample, an independent board-certified physician in your state reviews the results, and they are released to your secure online account. You can download a PDF and a doctor's version to share with a provider. If a result is concerning, Everlywell says a team member from its physician network will call you.

Sensa, from box to score. You open the kit, spit into the vial, give the color change a few minutes, and scan the vial with the Sensa app. In about 15 minutes you have a score and a tier, saved automatically to your history. There is no card to dry, nothing to mail, no registration beyond your app account, and no waiting for an email. Kits ship free, and there is no subscription. If you keep a multi-pack on the shelf, your next test is always within reach.

Time to Result

Everlywell runs on shipping time plus lab time. The kit takes three to five business days to arrive, your sample takes time to travel back, and Everlywell says results are generally ready within five business days after the lab receives the sample. For a first order, plan on one to two weeks from click to result. Every test is a fresh kit, so the cycle repeats each time you want a new number, though keeping a kit on hand removes the first leg.

Sensa takes about 15 minutes. Once the kit is in your hands, the result arrives in the time it takes to make breakfast. Whether that speed matters depends on your question. If you want to know how a rough week of sleep showed up in your body, a two-week lag blurs the answer badly. If you need one solid number for an annual physical, the wait is irrelevant.

Cost per Result and Cost per Year

Everlywell lists the test at $99. That is the price shown on the product page on October 27, 2026. Everlywell also offers an Everlywell+ membership that earns a monthly credit redeemable for its tests, according to its how-it-works page. We did not verify the membership price, so the figures below use the list price.

Sensa is $49 for a single kit, $99 for a three-pack, and $129 for a four-pack. That works out to about $33 per test in the three-pack and about $32 per test in the four-pack, with free shipping and no subscription. Here is what the two cost over a year at several testing frequencies, using Everlywell's list price and Sensa four-packs.

What You Get With the Result

Everlywell delivers a lab value with physician review. According to Everlywell's website, your report shows your hs-CRP and vitamin D results, reviewed by an independent board-certified physician before release, in a digital and printable format with a doctor's version for sharing. This is the kind of result you can hand to a clinician and have a conversation about, because it is on the same scale they use.

Sensa delivers a score, a tier, and a history. Each reading is a 0 to 100 score labeled In range, Worth watching, or Time to reset, time-stamped and stored in the app alongside every earlier reading. The history is the point. One score tells you little. A line of scores across the weeks you changed your sleep, cut back on alcohol, or started training again tells you something you can act on. Sensa does not diagnose anything, and the app will tell you so.

The honest framing. A lab value tells you where you stood against a population range on one day. A trend tells you which direction you are moving. Most people benefit from knowing both, and most people do not need the lab version very often.

When to Pick Which

Pick Everlywell when the number has clinical stakes. If your doctor asked for an hs-CRP, if you are following up on a previously elevated result, or if you want a value to bring to an appointment, you need a laboratory result. Everlywell gives you one without leaving home, and the vitamin D result rides along at no extra cost.

Pick Sensa when you want to watch the trend. If you are changing your diet, sleep, training, or stress load and want to see whether it shows up in your body, you need frequent, cheap, needle-free readings. Testing weekly or every other week with Sensa costs less than a single Everlywell test per month and gives you far more points on the chart.

Use both when you want anchor and direction. Many people land here. Take a lab hs-CRP once or twice a year as an anchor and use Sensa in the months between. Because the two live on different scales, compare direction rather than numbers: if your Sensa trend has been drifting toward Worth watching and your next lab value also rose, the two are telling the same story in different languages.

Alternatives to Everlywell for Inflammation Testing

Everlywell is not the only mail-in option. LetsGetChecked sells a mail-in finger-prick CRP test, with blood test kits that generally run $89 to $119. Labcorp OnDemand sells an hs-CRP test for $69 that you buy online and complete with a venous draw at a Labcorp location, with results posting about a day after the sample reaches the lab. Both figures were verified in August 2026 for our roundup of the best at-home CRP tests, and our newer guide to at-home hs-CRP kits with lab results goes deeper on the lab options. Sensa rounds out the list as the only saliva option, and our Sensa versus mail-in kits page compares the two approaches head to head.

Frequently Asked Questions

Is Sensa an alternative to Everlywell?

For trend tracking, yes. Sensa gives you a saliva CRP score at home in about 15 minutes for about $32 to $49 per test, which makes frequent testing practical in a way a $99 mail-in kit does not. For a laboratory hs-CRP value, no. Sensa does not produce a clinical number, so if your doctor wants an hs-CRP result, Everlywell or another lab-based test is the right tool.

Does Everlywell test CRP or hs-CRP?

hs-CRP. Everlywell's Vitamin D & Inflammation Test lists high-sensitivity C-reactive protein (hs-CRP) and vitamin D as its two markers, according to Everlywell's website. hs-CRP is a higher-sensitivity version of the standard CRP assay that can quantify the low levels of CRP associated with chronic, low-grade inflammation.

Can I get Everlywell results faster?

The timeline is set by shipping and lab processing. Everlywell says the kit usually arrives within three to five business days and results are generally ready within five business days after the lab receives your sample. You can shorten the front end by keeping a kit on hand and mailing your sample the day you collect it. We did not find an expedited option on the pages we reviewed. If you need a same-week lab value, a draw-site test such as Labcorp OnDemand is usually quicker, and for a same-day read, Sensa gives a saliva score in about 15 minutes, though it is a different measurement.

Which is cheaper, Sensa or Everlywell?

Sensa, per test and per year. Sensa is $49 for a single kit and about $32 per test in a $129 four-pack, while Everlywell lists its Vitamin D & Inflammation Test at $99. Testing monthly for a year costs about $387 with Sensa four-packs versus $1,188 with Everlywell at list price. The two are not the same product, though: Everlywell's price includes a lab hs-CRP value, a vitamin D result, and physician review.

Can a saliva CRP test replace a blood test?

No. Saliva CRP and blood hs-CRP are different fluids measured on different scales, and a Sensa score is not an hs-CRP value. It should not be compared with blood reference ranges or used in place of a test your doctor ordered. Saliva testing is for watching your trend between lab tests; blood testing is for getting a clinical number.
