Updated October 16, 2026. By FitScript Editorial.
SiPhox Health and FitScript both help people track their blood biomarkers over time, but they collect the data differently. SiPhox Health sends an at-home kit that collects a small sample from the upper arm, on a cadence you choose. FitScript centres on reading the labs you already have, with lab panels drawn at a lab or at home in select areas when you want new testing. This page sets their published facts side by side, each one 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.

The main difference is how the sample is collected. SiPhox Health mails an at-home kit called EasyDraw that collects a small blood sample from the upper arm in about five minutes, and you choose whether a new kit arrives monthly, quarterly or every six months. FitScript's Protocol membership is built around reading labs, whether you bring them from your doctor or another testing company, or order a panel that is drawn at a lab, or at home in select areas.
That shapes how often people test. SiPhox Health builds a testing cadence into its membership. FitScript lets you test one body system at a time when you want to, or add provider access and group coaching through its Peak plan.
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.
FitScript prices the reading layer and the testing separately. Protocol is $20 per month including a 7-day trial, with cancel anytime, and covers Atlas, the FitScore on labs you already have and a full daily protocol. Peak is $99 per month or $999 per year and adds provider access and two group coaching calls a week. Lab panels are sold on their own, from $49 up to $499 for FitScript Complete, and each panel page lists the panel as HSA/FSA eligible.

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.
FitScript sells panels by body system rather than one fixed bundle. FitScript Essential, with 40+ biomarkers, is $149. FitScript Complete, with 70+, is $499. A Hormone Panel is $229, Thyroid Complete is $149, Metabolic + Insulin is $99, Cardiovascular Deep is $129 and Heavy Metals is $179, with single tests such as Vitamin D at $49. Add-on panels are drawn from the same sample as a core panel, so going deeper on one system needs no second visit.

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.
FitScript emails a digital lab requisition when you order, which its panel pages describe as valid at 3,000+ Quest and Labcorp locations nationwide. You can walk in to a nearby lab, with no appointment needed, or choose at-home phlebotomy in select areas. Preparation is listed per panel. FitScript Essential, for example, asks for a 12-hour fast with water only.
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.
FitScript shows turnaround on each panel page, from 3 to 5 business days for panels such as Thyroid Complete and FitScript Essential up to 7 to 10 business days for Heavy Metals. Results land in the Atlas dashboard, where every marker is read against optimal ranges as well as the lab's standard range. They feed a FitScore, a Bio Age and a Living Health Map that groups markers by body system, and then a daily protocol built around them.

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.
FitScript's AI is called Atlas. It analyses labs against optimal ranges, syncs wearable data, tracks the FitScore over time and builds a protocol of supplements, nutrition and training, with AI chat for follow-up questions. When prescription treatment may fit, FitScript describes licensed physicians who review each case, with provider messaging over HIPAA-compliant channels, and the provider decides whether anything is prescribed. provider access and group coaching sit in the Peak plan.
So both pair an AI with a written plan. The main practical difference is that FitScript adds a licensed clinician route through its Peak plan, while SiPhox Health positions its service as wellness only and suggests consulting your own physician.
Yes, with both. 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.
Upload is the centre of FitScript rather than an extra. Its upload page lists PDF reports from Quest, Labcorp, Function, Lifeforce, Superpower and hospital systems, as well as phone photos of paper printouts, and states that Atlas has a read in under a minute. Wearable syncing covers Oura and WHOOP.
If most of your data already exists, from annual physicals, a past testing membership or a wearable you use every day, the upload path matters more than the test menu. If you have no recent labs at all, the test menu matters more.
See Upload your labs
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.
FitScript starts with the labs a person already has. Protocol at $20 per month, including a 7-day trial, adds Atlas, the Health Score and personalised recommendations on top of uploaded labs from almost any provider. When you want new testing, you choose a panel by system and give a standard venous sample at one of 3,000+ Quest and Labcorp locations, or at home in select areas.
Panels such as FitScript Complete go up to 70+ biomarkers in one draw, and add-ons run from the same sample. Results are read against optimal ranges as well as the standard range, across up to 149 biomarkers, and Peak adds provider access for people who want a licensed clinician involved.
A yearly total depends on the cadence you choose. SiPhox Health lists $99, plus shipping and handling, as an introductory price, with the membership renewing on a monthly, quarterly or six-monthly cadence, so check its checkout for what each renewal costs at the cadence you want. On FitScript, twelve months of Protocol is $240 before any lab panels, single panels run from $49 to $499, and Peak is $99 per month or $999 per year.
If you want to test often from home, a kit subscription is built for that. If you mainly want existing labs read, or a broad venous panel once or twice a year, the FitScript options may fit better. Prices change, so check each company's current pricing before you decide.
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 is a good fit for someone who already has bloodwork, from a doctor, an insurer-covered physical or another testing service, and wants it read against optimal ranges by an AI they can question. It also suits people who want to test one system at a time, such as thyroid or heart health, and pay for that panel alone, or who want provider access and group coaching inside the Peak plan.
People in between can use both. A SiPhox Health PDF report can be uploaded to FitScript, which reads lab reports regardless of who ordered the panel.
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 how you want to collect samples. If you want painless at-home kits on a set cadence, with the panel switchable each time, SiPhox Health is designed for that. If you already have labs, want them read against optimal ranges with an AI you can question, and prefer standard venous panels picked one system at a time, FitScript is designed for that.
Whatever you choose, a licensed clinician is the right person to interpret results that fall outside the standard range.
It depends on how often you test. SiPhox Health lists $99, plus shipping and handling, as an introductory offer, renewing on a monthly, quarterly or six-monthly cadence. FitScript Protocol is $20 per month including a 7-day trial, and lab panels are priced separately from $49. Check both companies' current pricing, since prices change.
Yes. FitScript reads uploaded PDF reports and photos from other providers and reads them against optimal ranges.
Yes. SiPhox Health sends an EasyDraw kit that collects a small sample from the upper arm in about five minutes, which you mail back overnight to a CLIA-certified lab. FitScript panels are drawn at a Quest or Labcorp location, or at home in select areas.
SiPhox Health lists 31 biomarkers per Longevity Essentials test, with the Ultimate 360 upgrade listed at 60 in its FAQ. FitScript reads up to 149 biomarkers across 11 systems, with FitScript Complete covering 70+ in one draw.
SiPhox Health states that results are typically ready 7 to 10 days after the sample reaches its lab. FitScript lists 3 to 5 business days for FitScript Essential, up to 7 to 10 for Heavy Metals.
SiPhox Health lists all its tests as HSA/FSA eligible and offers an itemised receipt if a card is declined. FitScript lists each lab panel as HSA/FSA eligible on its panel page. Check with your plan administrator to confirm.
Sai is SiPhox Health's AI health advisor in its dashboard, which can analyse uploaded reports and wearable data. Atlas is FitScript's AI, which reads your labs against optimal ranges and builds your protocol, with provider access in the Peak plan.
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.
