Upload your lab report instead of typing values in. FixFirst reads every marker and tells you which ones are worth acting on, ranked by clinical urgency, adjusted for your age and sex.
Three steps from lab report to plain-English interpretation. About 45 seconds end to end, online, with nothing to install.
Any lab report works: Quest, Labcorp, NHS, hospital portals, at-home kits. PDF or a photo of the printed page. There's no form to fill in and no values to type — the analyzer reads the report itself.
Each value is compared against published clinical ranges, adjusted for your sex and age. A hemoglobin of 13.3 g/dL is low for a man and normal for a woman. The analyzer knows the difference; many tools don't.
Instead of 40 rows of numbers, you get the three findings most worth acting on, ranked by clinical urgency, each with what it means and what to do next.
Most tools that promise to help you understand your results ask you to type each one into a form. FixFirst skips that step.
Instead of typing dozens of values, units, and reference ranges into a form, upload the report itself, a PDF or a photo of the printed page, and FixFirst reads every value for you. That's faster than manual entry and removes the copy errors that come with retyping small numbers off a lab printout. You still get to input your lab results in the sense that matters: your data goes in and a plain-English interpretation comes out. It just doesn't require a keyboard.
This works whether you want to interpret lab results online from Quest, Labcorp, an NHS portal, a hospital system, or an at-home test kit. It's free, there's no account to create, and the reference ranges adjust for your sex and age automatically. Upload once and every marker on the report gets checked.
Kantesti, testresult.ai, Docus AI, and SiPhox also analyze uploaded reports. ChatGPT can explain what a marker measures. Here's where they differ.

This table covers the upload-based tools. Our roundup of the best AI blood test analyzers (2026) scores all of them, plus testing services like InsideTracker and Function Health, on six factors — and names the cases where another tool is the better pick.
Before or after running the analyzer, this is the framework clinicians use when they review a panel.
Every report prints a reference range next to each marker — the values considered normal for the lab's population. Results outside it are flagged H or L. Start there.
Slightly out of range is not the same as far out. A ferritin of 29 ng/mL (range 30–400) is barely low. A ferritin of 6 is significantly depleted and likely symptomatic. Degree matters.
Many printed ranges are population averages. Normal hemoglobin for a 25-year-old man (13.5–17.5 g/dL) differs from a woman of the same age (12.0–15.5 g/dL). FixFirst applies these adjustments for you.
One marker tells part of the story. Low ferritin alongside low hemoglobin and high RDW points to iron-deficiency anaemia more clearly than any single value. The ranking weighs co-occurring findings.
Most full panels have five to ten markers slightly out of range. Acting on all of them at once is neither practical nor necessary. The top 3 tells you where to start, highest clinical impact first.
Reading a report and interpreting it are two separate jobs. FixFirst keeps them separate on purpose.
A language model reads your PDF or photo and pulls every marker: name, value, unit, reference range. It handles different lab layouts, abbreviations (MCH vs. mean corpuscular hemoglobin), and unit conventions (ng/mL vs. µg/L).
A medically reviewed rule engine compares each value to sex- and age-adjusted ranges from published guidelines (AACC, NHS). This step is deterministic, not AI-generated, which removes hallucination risk from the part that matters most.
An urgency algorithm ranks out-of-range markers by severity, direction, co-occurring findings, and your lifestyle context. You get a top 3, not a wall of flags to decode yourself.
No dashboard to learn, no subscription to cancel. Three priorities, in plain English.
