SiPhox Health is best for frequent, repeat at-home biomarker tracking with an AI read. LetsGetChecked is best for discrete home test kits with clinical follow-up on abnormal results. AMORTAL is neither: it takes whichever you use and decides when an at-home result is enough to act on versus confirm with a venous draw, what to watch, and when not to retest.
SiPhox Health and LetsGetChecked are two of the more popular ways to test biomarkers from home — and they’re built on different bets. SiPhox leans into a quick, self-collected panel designed for frequent repeat tracking, with an AI read on top. LetsGetChecked leans into discrete home test kits with results online in a few days and clinical follow-up when something comes back abnormal.
Both answer “what do my numbers look like?” from your kitchen table, in their own way. Neither is built to answer the harder question that comes next: “is this single at-home reading enough to act on, what should I actually change, and when do I confirm or retest?” That’s the gap this page is about — and where AMORTAL fits, on top of whichever one you pick. It’s educational, not medical advice.

Use SiPhox or LetsGetChecked for the at-home test. Use AMORTAL to decide when a result is enough to act on, what to ignore, what to watch, and when to confirm with a venous draw.
The short version: who each is for
Two of these collect at-home data in different shapes; the third decides what to do with whichever you have — including whether one reading is enough to act on. Here’s the honest split.
Which one fits which job
SiPhox HealthBest for repeat at-home trackingA quick, self-collected at-home test built for frequent repeat tracking — SiPhox advertises a 5-minute collection, 50+ biomarkers, results in roughly 7–10 days, and an AI read called Sai. Strongest when you want to check the same markers often without leaving home.
LetsGetCheckedBest for discrete kits + clinical follow-upDiscreet home test kits with results online in around 2–5 days and clinical follow-up when a result comes back abnormal. Strongest when you want a private at-home kit with a clinician in the loop on anything out of range.
AMORTALBest for deciding what to do nextNot a lab. A longitudinal decision layer that reads whatever at-home results you already have — from either provider — and returns one ranked next action, a watchlist, a clinician-ready question, and whether to confirm before you act. Including when to do nothing.
This isn't an "A beats B." SiPhox and LetsGetChecked answer what are my numbers in different at-home shapes; AMORTAL answers what should they change — and whether one reading is enough to change anything. The strongest setup is one provider plus AMORTAL.
SiPhox vs LetsGetChecked vs AMORTAL, at a glance
Tap between the three to see what each is actually responsible for.
What each one owns
Same goal — better decisions from at-home biomarkers — split into two collection shapes and one decision layer.
SiPhox — quick repeat at-home panels
A self-collected at-home test built for frequent tracking: SiPhox advertises a 5-minute collection, 50+ biomarkers, results in roughly 7–10 days, personalized supplement and lifestyle recommendations, and an AI read called Sai.
You want to check the same markers often, from home, with an AI read on the result. Verify the current biomarker count, turnaround and price before buying.
LetsGetChecked — discrete kits with follow-up
Home test kits ordered to your door, returned by mail, with results online in around 2–5 days (as advertised) and clinical follow-up when a result is abnormal — a private at-home option with a clinician in the loop on out-of-range findings.
You want a discrete kit and a clinician to follow up on anything abnormal. Verify the current catalog, turnaround and pricing before buying.
AMORTAL — the decision layer
Not a lab. It takes either provider's at-home results, normalises them into a memory, and produces one ranked next action, a watchlist, a clinician-ready question, and a call on whether to act now or confirm first — with restraint built in.
You already have an at-home result and the real question is "what now?" — is this enough to act on, what to change, what to ignore, what to watch, and when a retest is actually worth it.
AMORTAL has no direct integration with either — you bring the data in by upload or manual entry.

Where AMORTAL fits — whichever you pick
The model is the same regardless of which at-home option you choose: let the provider do the testing, then run the result through a decision process instead of a dashboard.
- Bring the result in. Upload your SiPhox or LetsGetChecked report, or enter the key markers — there's no direct integration, so you carry the data over.
- Normalise into memory. AMORTAL files each biomarker into a longitudinal record, not a one-off screen.
- Connect the context. Results are linked to your goals, symptoms, wearables, medications and constraints.
- Activate the standards. The guidelines and decision rules that actually apply to your situation switch on.
- Produce a Decision Contract. One change at a time, with the expected signal and the window written down in advance — or a call to confirm before changing anything.
- Rank one Next Best Action. Not ten. The single highest-value move — which may be "confirm this reading first" or "do nothing yet."
- Set the watchlist. Markers worth re-checking get an expected direction and a recheck window.
- Close the loop. When the next panel or outcome signal arrives, AMORTAL checks whether the action worked — and keeps or discards it.
A decision loop, end to end
Here’s the same flow on a single example — illustrative numbers only, not a target or a reference range.
From an at-home result to a tracked outcome
Your SiPhox or LetsGetChecked panel returns an HbA1c a touch above your usual range (illustrative only — not a target or a reference range). On a dashboard — or in a chat reply — that's a red number and a vague nudge.
AMORTAL files it next to your prior readings, your goals, your medications and your wearable trends — read as a trajectory, not a single dot.
One lever, not five. If this is a single at-home data point, the first move may be to confirm rather than change — the expected signal and the window to see it are written down before anything happens.
Framed as a clinician-ready question — "given this trend, is [one specific lever] the right first move, or is this worth confirming first?" — not a treatment directive AMORTAL has no authority to give.
The marker goes on watch with an expected direction and a recheck window — so you retest when it's informative, not on a guess or every time a kit is convenient.
At the next reading, AMORTAL checks: did it move as expected? If yes, the change earns its place. If not, it's dropped — no story told over one noisy at-home dot.
AMORTAL doesn't diagnose and isn't a substitute for your clinician — anything urgent goes to a professional, now.
Is an at-home result enough to act on?
At-home convenience is genuinely valuable — but it’s easy to read one self-collected panel as a verdict. Before you change anything off the back of a single result, tick what’s honestly true. The more boxes you can tick, the safer it is to act on your own.
Is this at-home result enough to act on?
Answer honestly for the result in front of you. The fewer boxes you tick, the more this is a signal to confirm — not a decision.
Tick what's true above
Your read on whether to act appears here.
A guide, not a guarantee. Anything urgent or alarming goes to a clinician now, whichever provider produced the number.
Where each is strongest — and where it isn’t
In fairness to all three:
- SiPhox is strongest when you want frequent, repeat at-home tracking of the same markers with an AI read — and less ideal if your bottleneck is deciding what a single self-collected reading should actually change.
- LetsGetChecked is strongest when you want a discrete home kit with clinical follow-up on anything abnormal — and less ideal if you’re after dense, frequent self-tracking rather than occasional kits.
- Verify before you buy. Biomarker counts, turnaround, kit catalogs, prices and promotions change for both — confirm the current details on each provider’s own pages.
- One at-home reading is a beginning, not an answer. Some results need a clinician or a confirmatory venous draw; AMORTAL should never be read as a diagnosis, whichever provider produced the number.
Bring your results into a decision, not a dashboard
AMORTAL doesn’t need to be where you buy your tests. The stronger model is to let a provider like SiPhox or LetsGetChecked do the testing, then use AMORTAL as the longitudinal decision system around those results. Upload the report, or enter the markers that matter. AMORTAL turns the result into memory, evaluates whether one at-home reading is enough or worth confirming, ranks the next best action, sets a watchlist for the signals to expect, and later checks whether the action actually worked.
Already have results from SiPhox or LetsGetChecked? Bring them into AMORTAL and ask the only question that matters: “What should I do next?”

Frequently asked
SiPhox vs LetsGetChecked — which should I choose?
It depends on how you want to test. SiPhox is strongest for frequent, repeat at-home biomarker tracking — it advertises a 5-minute self-collected test, 50+ biomarkers, results in roughly 7–10 days, and an AI called Sai. LetsGetChecked is strongest for discrete home test kits with clinical follow-up on abnormal results and online results in around 2–5 days. Both publish their own panels, turnaround and pricing, which change often — verify the current details before buying. Whichever you pick, AMORTAL works on top of the results.
Can AMORTAL work with results from either SiPhox or LetsGetChecked?
Yes. AMORTAL is lab-agnostic and works from results you already have — you bring them in by uploading the report or entering key markers (there's no direct integration with either). It normalises the biomarkers into a longitudinal memory, connects them to your goals, wearables and protocols, and returns one ranked next action rather than another dashboard. The provider you chose stays your data source; AMORTAL is the decision layer that also weighs whether an at-home reading is enough to act on.
Does AMORTAL replace SiPhox Health or LetsGetChecked?
No. They do a different job. SiPhox and LetsGetChecked collect and report biomarker data; AMORTAL decides what that data should change, what to ignore, what to watch, and when an at-home result should be confirmed with a venous draw or a clinician. Most people who use AMORTAL keep their provider for the testing and use AMORTAL to turn each result into an auditable decision and an outcome loop.
Should I just test more often, or run a bigger at-home panel?
Not automatically. At-home convenience makes it easy to test often and to run broad panels — but more readings and more markers also mean more borderline results that tempt over-reaction, and a single at-home reading can move on normal variation. AMORTAL evaluates whether a result is a confirmed trend or a one-off, whether it's worth confirming with a venous draw, whether a clinician should weigh in, and when a retest would actually be informative versus premature.
Is an at-home finger-prick result as reliable as a clinical lab draw?
An at-home self-collected sample is convenient and useful for tracking trends, but a single reading can be affected by collection technique, timing and normal day-to-day variation, and some markers are better measured from a venous draw. That's exactly the call AMORTAL is built for: it weighs whether an at-home result is a confirmed trend you can act on or one worth confirming before you change anything — and anything alarming or far out of range goes to a clinician now, not to an app.
SiPhox has an AI called Sai — how is AMORTAL different?
An AI read like Sai answers questions and surfaces recommendations in the moment. AMORTAL produces a Decision Contract: it writes down one change, the single signal you'd expect it to move, and the window to watch — in advance — then checks later whether it actually worked. It's auditable and outcome-tracked rather than conversational, lab-agnostic across providers, and deliberately built to recommend doing nothing, or confirming a result first, when that's the right call.
