A note is the fastest place to put a number, and free text is the worst structure for a value. No unit column, no reference range, no date field, and no chart. Doctano reads the report instead, keeps the unit and range from that lab, and puts each marker on its own history with a link to the source.
Why the note happens
The report arrives as a PDF. You are on a phone. The appointment is in ten minutes. You copy the two values you are worried about into a note and close the file. This is a reasonable response to a bad moment. The note is already there, it opens instantly, and it asks for nothing.
The note is good at capture. It can hold context a form cannot: how you felt, what you ate, what you want to ask. It is a record of the moment, not a record of the result.
That difference matters later. A number without its unit, its reference range, and the date the sample was taken is hard to interpret even a week after the appointment, and much harder a few years on.
What free text cannot do
- No unit column. The value and the unit sit in a sentence, or the unit is left out.
- No range. The reference range from that report is not a field, so normal becomes a memory.
- No date field. The note's timestamp is when you typed, not when the sample was taken.
- No conversion. The same marker in mg/dL and mmol/L becomes two unrelated lines.
- No marker identity. Vitamin D typed once and 25-OH D typed later may never join.
- No chart. Seeing a trend means reading every line again.
- No source. The line has no link back to the page it came from.
None of that is a criticism of notes. Free text is for thoughts. A lab result is a small record with a name, a value, a unit, a range, a date, and a source, and it needs a structure that holds all six.
What a structured version looks like
Doctano extracts test names, values, units, reference ranges, panels, and report dates. It maps markers to LOINC codes and normalizes names and units across labs so a result from one lab lines up with the same marker from another. Each result is classified against the reference range printed on its own report as healthy, borderline, critical, or unknown. A result without a usable range stays unknown. Those labels are not diagnoses.
Every extracted value links back to the original uploaded report, and the report page has View original. The timeline and per-marker history show change across reports, and an overall health score per profile gives a rough summary.
Profiles keep people's timelines separate. Sharing is with an existing Doctano account, and people with access can view and add reports.
DoctanoAI answers from the selected profile's biomarker values, history, out-of-range results, and report text, and may link back to reports. It does not diagnose, prescribe, or recommend dosages, and it can be wrong.
The app is free, in the browser, mobile-first, with an English interface. There is no native iOS or Android app, and Google Sign-In is the only sign-in method. Export is not available yet, so the note can still be the place you keep a plain copy.
Where a note is still the right tool
Keep the note for what it does well. Write down the question you want to ask, the symptom you noticed, the food or medicine change you want to mention. Then put the report itself somewhere that can hold the value, the unit, the range, and the date. The two records do different jobs, and neither one needs to be deleted.
If you do keep values in a note, write dates in one format and write each marker the same way every time. It will still not chart, but it will be easier to read.
Side by side
| What matters | A notes app | Doctano |
|---|---|---|
| Speed of capture | Very fast, one line | One upload per report, then no typing |
| Structure per value | Free text, whatever you type | Name, value, unit, range, panel, and date |
| Units and ranges | Only if you copied them | Normalized units, range from each report |
| Finding a value across years | Search the text, if you worded it consistently | Marker history across every report |
| Trend for one marker | No chart unless you build one | Yes, per marker |
| Source behind a value | No, unless you pasted a link | Every value links to its original report |
| Family separation | Separate notes, or one shared note | Profiles in one account, sharing with an existing Doctano account |
| Explaining a marker | Only if you wrote it down | DoctanoAI and per-biomarker context |
| Effort per report | Retype what you need | One upload |
The honest recommendation
Keep the note if
- You are capturing a symptom, a question, or how you felt.
- You need a quick copy of one number for an appointment.
- You want a plain text record you can read anywhere.
- You are not trying to compare values across years.
Use Doctano if
- The value needs its unit, range, and date attached.
- You use more than one lab and the units differ.
- You want a per-marker chart without building it.
- You want to check a number against the page it came from.
The two belong together. The note holds what you noticed and what you want to ask. Doctano holds the extracted values, their ranges, and the reports behind them. Use the note to remember the question, and the timeline to answer it.
