Put the page on a flat surface in even, indirect light, hold the phone parallel to it, and fill the frame with one page at a time. Keep all four edges visible, avoid shadow and glare, and check the image before you upload. A lab PDF is better than a photo when you can get one.
A readable photograph is not about a good camera. It is about even light, a flat page, and a straight angle. Those three fix most failed uploads.
Get the PDF first
If the lab or hospital portal offers a download, use it. A PDF keeps the text selectable and the columns intact. An email from the lab may also carry the original file. Photograph the paper only when the digital copy is not available.
If you only have paper, photograph the original, not a photocopy. A photocopy has already lost contrast and may have cut off a margin.
The checklist
- Use indirect daylight. A hard lamp, a flash, or direct sun creates glare and shadow.
- Lay the page flat on a plain, dark surface that contrasts with the paper.
- Hold the phone parallel to the page, not at an angle.
- Fill the frame with one page, and keep all four corners and a little margin.
- Tap the screen to focus on the values, then hold still.
- Do not use digital zoom. Move the phone closer instead.
- Press the page flat, or weight the corners, to remove curl at the spine.
- Photograph multiple pages one at a time, in order.
| Problem | What it does to the image | Fix |
|---|---|---|
| Shadow across the page | Dark bands hide digits | Move the light source or step back from the lamp |
| Glare on glossy paper | Text is washed out | Change the angle so the reflection misses the lens |
| Curl at the spine | Columns bend and go out of focus | Flatten the page or weight the corners |
| Cropped edge | The reference range or unit is missing | Include the full page and margin |
| Too far away | Digits are too small to read | Fill the frame with one page |
| Two pages in one photo | Both pages are small and skewed | One page per image |
| A finger in the frame | A value is covered | Hold the page by the edges |
Check the image before uploading
Zoom in on the smallest values and the reference range column. If a digit is ambiguous, retake the photo. Check that the patient's name and the collection date are visible, and that the page is not rotated or upside down.
What makes a report hard to read
- Handwritten corrections or a doctor stamp over a value.
- Thermal paper that has faded or been folded.
- Coloured paper or a coloured scan that reduces contrast.
- Dense multi-column layouts where two panels share a line.
- Staples, folds, or a binding that obscures a column.
- A screenshot of a portal page with small text and cropped columns.
If the upload fails
Doctano accepts PDF, PNG, JPEG, and TIFF files up to 50 MB each. If a phone saves photos in HEIC format, export or convert to JPEG first. A photograph that is too dark, too small, or cropped may upload but extract poorly; a clearer copy is worth the extra minute.
Privacy while photographing
A lab report carries your name, age, and sometimes an identifier. Photograph it at home rather than at a public counter, and upload it only to a service you trust. Doctano keeps reports private to your account and the profiles you share; there are no public report pages.
How Doctano handles a photo
Doctano reads the values, units, ranges, and dates from the image, and keeps the original file linked to the results. Extraction can be wrong on a blurred or crowded page. If a value looks wrong, open the original and compare before relying on it.
