Translate your blood test results into plain English
Lab reports are full of abbreviations, codes, and numbers with no context. BloodId translates them into clear language — what each biomarker measures, whether your value is in range, and what high or low might mean.
From lab jargon to plain English
Upload a PDF, scan, or photo of your results and BloodId reads every biomarker — WBC, ALT, eGFR, HbA1c and the rest — then explains each one in everyday language instead of medical shorthand.
Because the interpretation is based on your own uploaded report, the context is specific to you: your values, your units, and your reference ranges, not a generic article.
What is actually on a blood test report
Most lab reports show the same four things for every test, laid out in columns. Once you know what each column is, the page stops looking like code.
The test name or its abbreviation (for example "WBC" for white blood cells). Your result — the measured number. The unit that number is in (such as mg/dL or mmol/L). And a reference range: the interval the lab considers typical, often with an "H" or "L" flag when your value falls above or below it. Some reports also show your previous results so you can see the direction of change.
BloodId reads all four for every biomarker and restates them as a sentence: what the test measures, your value with its unit, and whether it sits inside or outside your report’s reference range.
What a reference range is — and why labs differ
A reference range is the interval of values seen in most healthy people for that test. It is not a personal target and not a pass/fail line; it is a statistical band that each laboratory sets for its own equipment and the population it serves.
That is why the same test can show a slightly different range on reports from two labs, and why ranges can vary by age and sex. It is also why a value flagged "H" or "L" simply means it is outside that lab’s band — which is a prompt to look closer and talk to a professional, not a diagnosis on its own.
BloodId always shows the reference range that came with your report next to each value, and when results span multiple labs it explains which range it is using.
Common blood test abbreviations
A large part of "translating" a report is just expanding its shorthand. Common ones include: WBC (white blood cells), RBC (red blood cells), HGB (hemoglobin), HCT (hematocrit), PLT (platelets), MCV (mean cell volume).
On the chemistry side: ALT and AST (liver enzymes), eGFR and creatinine (kidney function), HbA1c (average blood sugar), TSH (thyroid), LDL and HDL (cholesterol fractions), CRP (an inflammation marker), and ferritin (an iron store). BloodId recognises these and hundreds more, including the aliases different labs use for the same test.
How to read your results in four steps
Find the value and its unit. The same test can be reported in different units, so the number only means something alongside its unit.
Compare it to the reference range on the same row, and note any H/L flag. Being just outside a range is common and is not automatically a problem.
Look at the trend. One reading is a snapshot; the direction across several tests is usually more informative than a single value.
Bring anything unclear or flagged to a qualified healthcare professional. A translation tells you what a result says — a clinician tells you what it means for you.
Works with US and international reports
BloodId understands both US conventional units (mg/dL, g/dL) and the SI units used across Europe (mmol/L, g/L), and interprets each value against the matching reference range — so a report from a US lab or a European lab is translated correctly.
It also lines up results reported in different units on a single chart — useful if you have tested in more than one country — by converting at display time while keeping each lab’s original numbers intact.

Frequently asked questions
- How do I read my blood test results?
- Read each row as four parts: the test name, your value, its unit, and the reference range. If your value is inside the range there is usually no flag; if it is outside, the report marks it "H" (high) or "L" (low). Comparing the value to its range, and watching the trend over several tests, is the core of reading a report. BloodId does this for every biomarker and writes it out in plain language.
- What are normal lab values?
- The "normal" values for a test are the reference range printed on your own report — the band the lab expects for most healthy people. There is no single universal set of numbers: ranges vary by laboratory, method, age, and sex, which is why BloodId shows the range that came with your result rather than a generic one.
- What does "H" or "L" next to my result mean?
- It means your value is above ("H") or below ("L") the lab’s reference range for that test. It flags a value worth looking at; it is not by itself a diagnosis, since values sit just outside the range for many ordinary reasons. Use it as a prompt to review the trend and speak with a professional.
- What does "non-reactive" mean on a blood test?
- On tests that screen for a substance or antibody (for example certain infection screens), "non-reactive" means the test did not detect it — generally reported as a negative result, as opposed to "reactive". For what it means for your specific test, check the report’s notes or ask the ordering professional.
- Why are the reference ranges on my two reports different?
- Because each lab sets its own ranges for its equipment and population, and ranges can differ by age and sex. BloodId keeps each report’s own range and, when your results span multiple labs, tells you which range it is charting against.
- Does it handle US and European units?
- Yes. BloodId reads both US conventional units (mg/dL) and international SI units (mmol/L), interprets each against the correct reference range, and lines up multi-country results on one chart.
- What can I upload?
- A PDF lab report (digital or scanned) or a photo of a printed result in JPG, PNG, or WEBP. BloodId reads scans and photos directly.
- Is the blood test translator free?
- Yes. You can sign up and translate your results for free — new accounts include 3 free uploads and AI chats.
- Is the translation a medical diagnosis?
- No. BloodId provides educational explanations only and does not diagnose or treat conditions. Always consult a qualified healthcare professional.
