InsideTracker and SiPhox Health both turn blood testing into a health plan, but they are built differently. InsideTracker sells a yearly platform membership, with blood tests bought on top or in a bundle, and adds DNA and wearable data to its analysis. SiPhox Health sends an at-home kit that collects a small sample from the upper arm, on a cadence you choose. FitScript publishes this page and is shown alongside them as a third option built around reading the labs you already have. Every fact below is linked to where it came from.
FitScript publishes this comparison and is one of the services compared. Competitor facts come from each company's own website as of October 16, 2026. Prices and features change, so check their current terms before you decide.

InsideTracker lists the InsideTracker Membership at $149 as an annual platform fee, with no blood test included. Membership with one Ultimate Blood Test is $489, including the annual platform fee, and InsideTracker calls it the most popular option. Bundles bring the price per test down. Membership with two Ultimate tests is listed at $761, down from $829, and membership with four is listed at $1,305, down from $1,509. Members can also buy Ultimate tests on their own at $340 each, or $578 for two and $1,088 for four.
InsideTracker's help centre states that memberships are annual and that you can cancel at any time, keeping access to the platform until the membership expires one year from activation. Add-ons listed on its tour page include InnerAge for biological age, a DNA kit and an Estradiol and Progesterone test.
SiPhox Health lists a price of $99, down from $124, plus shipping and handling, as an introductory offer. Its home page states that the membership renews on the cadence you pick, monthly, quarterly or every six months, with no monthly fees and the option to change cadence or cancel anytime. Its FAQ says the membership includes at-home testing with your choice of panel, personalised insights and action plans, supplement recommendations, the Sai AI, unlimited third-party lab uploads, wearable integrations and one dashboard.
SiPhox Health also lists member pricing on extras, including a Prenuvo whole-body MRI at a discounted price, coaching credits for a 30-minute video call or a written plan, and a gut microbiome test. The Ultimate 360 panel is an upgrade, which its FAQ lists at an additional $125.

InsideTracker's Ultimate Blood Test looks at up to 54 biomarkers. Its help centre groups them into 10 healthspan categories, among them heart health, hormone balance, sleep, inflammation, metabolism and recovery, with markers such as ApoB, hsCRP, HbA1c, fasting insulin in the US, cortisol, SHBG, ferritin, vitamin D and RBC magnesium. Estradiol and progesterone are add-ons at checkout.
InsideTracker also offers a DNA kit, which it says covers up to 38 wellness traits based on 20,000 genetic markers, and an InnerAge analysis for biological age. Its site describes InsideTracker as combining blood, DNA, biological age and wearable data in one platform.
SiPhox Health includes four core panels with membership, Longevity Essentials, Thyroid Focus, Hormone Focus and Heart and Metabolic, and members can switch between them anytime. Longevity Essentials lists 31 biomarkers per test, among them HbA1c, ApoB, lipoprotein(a), hsCRP, TSH, cortisol, DHEA-S, SHBG, free testosterone, vitamin D and ferritin, along with ratios such as triglycerides to HDL and ApoB to ApoA1. The Ultimate 360 upgrade is described as its most comprehensive panel, which its FAQ lists at 60 biomarkers across heart, metabolic, hormone, thyroid, liver, kidney, inflammation and nutrient health.
SiPhox Health states that it works with CLIA and CAP accredited labs, and that its tests show a 95 to 99 percent correlation with standard venous draws. It describes itself as a wellness-only service that is not designed to diagnose, prevent or treat disease.
In the US, InsideTracker states that you can test at a nearby Quest lab or choose a mobile blood draw, where a phlebotomist comes to you. Members in New York, New Jersey, Rhode Island, Arizona and Hawaii must choose the mobile draw, which InsideTracker explains is because the law in those states keeps Quest from running discretionary bloodwork ordered through third-party companies. Members can instead test at a Quest location in another state if they select that state when activating the test. Canada is served with the mobile draw, and other countries can use a membership for uploaded results.
InsideTracker asks for a 12-hour fast before every blood test, no strenuous exercise for 48 hours, no alcohol for 24 hours and a morning test for the most accurate cortisol reading. It also asks members taking biotin to stop at least 72 hours before testing.
With SiPhox Health, testing happens at home. The kit arrives in 3 to 5 days, the EasyDraw collector attaches to the upper arm and collects a sample with a single click, and live one-on-one support is available while you collect it. You drop the kit at FedEx the same day with a prepaid label, and SiPhox Health says it uses temperature-controlled overnight shipping with a cold pack. No doctor's referral is needed. Its state coverage page lists Hawaii and New York as not yet served.

InsideTracker states that blood analysis and recommendations for InnerAge and Ultimate plans are available 7 to 10 business days after the blood test, with an email when results are ready. DNA kit results take 4 to 6 weeks after the kit arrives. Members see healthspan category scores, an InnerAge estimate and an Action Plan of recommendations, with a new habit goal each week.
SiPhox Health states that results are typically ready 7 to 10 days after your sample reaches its lab, with an email when the report is in your dashboard. Reports use a scoring system its clinical team calls the Axes of Wellness, across categories such as inflammation, metabolic and cardiovascular health, and members can export a PDF to see the data in a traditional table.
InsideTracker describes Terra as an AI health guide that uses your data to answer questions and guide health decisions. Its recommendations are built into an Action Plan that you can customise by swapping actions in and out, and its site states that the plan draws on an evidence base of more than 7,000 studies. InsideTracker's help centre points members with questions about specific markers to its knowledge base and blog.
SiPhox Health's AI is called Sai, which it describes as a personal AI health advisor in the dashboard that helps you understand your biomarkers and data from wearables and blood tests. You can upload a lab report as a PDF or photo for Sai to analyse. SiPhox Health describes Sai as an AI assistant for information and insights rather than a medical doctor, and its site lists coaching sessions as an extra.
InsideTracker members can upload past lab results from the dashboard as PDF, PNG or JPEG files, review what was scanned and then receive an analysis. If the automated process has trouble, members can enter results by hand or ask InsideTracker's data team to check them, which it says takes 3 to 5 business days. InsideTracker lists wearable connections for Fitbit, Garmin, Oura Ring and Apple Health on iOS.
SiPhox Health includes unlimited third-party lab uploads in its membership and states that it supports over 300 devices across ten categories, with Apple Watch, Fitbit, Oura, Eight Sleep and FreeStyle Libre the most common. It explains that correlating biomarkers with wearable data turns the numbers into lifestyle changes.
If you already get bloodwork through insurance and mainly want it interpreted, a reading membership may be the smaller cost. If you want several large panels a year with DNA and wearable data analysed together, a bundle built for that may suit you better. Prices change, so check each company's current pricing before you decide.
InsideTracker brings several kinds of data into one analysis. Its site lists blood biomarkers across 10 healthspan categories, an optional DNA kit, biological age through InnerAge and wearable data, with recommendations ranked by the impact they are likely to have. It describes more than ten years in wellness technology and a peer-reviewed study of more than 20,000 users.
InsideTracker also encourages a steady testing rhythm. Its help centre recommends retesting every three months to see how biomarkers respond, and its multi-test bundles lower the price of each test for people who plan to do that.
SiPhox Health makes frequent testing simple. Its site describes a five-minute at-home collection without vein draws or fingerpricks, a choice of monthly, quarterly or six-monthly kits, and the freedom to switch panels each time. For people who dislike needles or lab visits, that removes the main reason testing gets put off.
It also brings uploads, wearables and an AI advisor into one dashboard, states a strict no-sell policy for personal data, and lets members export or delete their data at any time.

InsideTracker is a good fit for someone who wants blood, DNA and wearable data analysed together, likes a customisable plan focused on nutrition, supplements, exercise and lifestyle, and plans to retest every few months to track change.
SiPhox Health is a good fit for someone who wants to test at home on a regular rhythm, prefers an upper-arm collector to a needle or a lab visit, and likes switching between heart, hormone, thyroid and longevity panels as goals change.
FitScript publishes this page and is shown in the table as a third option. It is built around reading the labs you already have rather than around one fixed testing bundle. Protocol is $20 per month including a 7-day trial and covers Atlas, its AI, the Health Score and personalised recommendations on uploaded labs. Lab panels are sold one body system at a time, from $49 for a single test to $499 for FitScript Complete, and Peak adds provider access and two group coaching calls a week.
Its upload page accepts PDF reports from Quest, Labcorp, other testing services and hospital systems, as well as phone photos of paper printouts, and states that Atlas has a read in under a minute. So results from either service compared here can be uploaded and read against optimal ranges.

Start with the tests you actually want. A large biomarker count is useful when it covers the systems you care about, such as thyroid, hormones, heart, liver and kidney health. Read each provider's published list and look for the specific markers you have been told to watch, for example ApoB, fasting insulin or free T3, rather than comparing totals alone.
Next, think about how often you will retest. Seeing a number move after three or six months is often more useful than a single snapshot, so include the cost of a second draw in any yearly total. Check where you can be drawn, how long results take and whether a clinician reviews anything outside the standard range.
Finally, look at what happens after the results arrive. Some people want a clear written plan, some want to ask questions about their own numbers, and some want a licensed provider involved. Membership terms, renewal pricing and HSA or FSA eligibility are worth reading closely too, since they change over time.
Choose based on what you need most. InsideTracker sells a yearly platform membership, with blood tests bought on top or in a bundle, and adds DNA and wearable data to its analysis. SiPhox Health sends an at-home kit that collects a small sample from the upper arm, on a cadence you choose. Read each company's current terms, since prices and features change.
Whatever you choose, a licensed clinician is the right person to interpret results that fall outside the standard range and to decide on any treatment.

Atlas is FitScript's AI. It reads every marker against optimal ranges as well as the standard range, builds a daily protocol and answers follow-up questions about your own results. The FitScore is one score built from your results, tracked over time.
Many people retest a panel after about three months to see whether changes in sleep, training or diet have moved the numbers, then every six to twelve months once results are steady. A clinician can suggest a schedule based on your own results.
No. FitScript publishes it and is one of the services compared. Every competitor fact links to that company's own site and shows the date we read it, so you can check anything that may have changed.
