Upload a lab report.
Every marker explained, flagged, and tracked over time.
This AI-powered tool reads and explains lab reports for educational purposes only; your report is sent to a third-party AI provider to generate the analysis. It is not a diagnostic tool and does not replace professional medical advice. Always discuss your results with a qualified healthcare provider.
A reference range is the middle 95% of results from a healthy reference population — which means one healthy person in twenty falls outside it by definition. A single flagged value is a prompt to look closer, not a finding on its own.
Ranges also differ between laboratories, because they depend on the equipment and methods used. Always read a result against the range printed on your own report rather than one you found online, including the ones below. Context matters too: recent illness, dehydration, exercise, pregnancy, the time of day and medication can all move a value without anything being wrong.
An A1C test measures your average blood glucose over roughly the previous three months — the lifespan of a red blood cell. Unlike a fasting glucose test it is not affected by what you ate this morning, which is what makes it useful.
| Result | A1C | Means |
|---|---|---|
| Normal | Below 5.7% | No diabetes |
| Prediabetes | 5.7% – 6.4% | Higher risk of developing diabetes |
| Diabetes | 6.5% or higher | Diagnostic range |
For most adults already diagnosed with diabetes the usual goal is an A1C of 7% or lower, tested at least twice a year — though targets are individual and set with your own clinician.
A complete blood count is the most commonly ordered blood test. It counts the three cell types in blood and describes their size and content. Typical adult ranges:
| Marker | What it measures | Typical range |
|---|---|---|
| White blood cells (WBC) | Immune cells — infection and inflammation | 4,000 – 10,000 /mcL |
| Neutrophils | The largest white cell group | 2,500 – 7,000 /mcL |
| Lymphocytes | Immune cells including T and B cells | 1,000 – 4,800 /mcL |
| Red blood cells (RBC) | Cells carrying oxygen | 4.0 – 5.4 M/mcL (F) · 4.5 – 6.1 M/mcL (M) |
| Hemoglobin (Hb) | The oxygen-carrying protein itself | 11.5 – 15.5 g/dL (F) · 13 – 17 g/dL (M) |
| Hematocrit (Hct) | Share of blood made up of red cells | 36 – 48% (F) · 40 – 55% (M) |
| MCV | Average red cell size | 80 – 100 fL |
| MCH | Average hemoglobin per red cell | 27 – 31 pg |
| RDW | How much red cell size varies | 12 – 15% |
| Platelets | Cells involved in clotting | 150,000 – 400,000 /mcL |
F = people with female-typical reference ranges, M = male-typical. Your report may use different cut-offs.
Take it to whoever ordered the test. They have the context this page cannot: why the test was requested, what your previous results looked like, what you are taking, and what else they found. A trend across several tests almost always says more than one value in isolation.
Contact them sooner rather than at your next appointment if a result is flagged as critical, if you have symptoms that worry you, or if you were told to expect a call and have not had one.
