About Reference Range

Reference Range makes small, sturdy stickers for the moments in medicine that deserve a marker: the last infusion, the glucose drink you did not enjoy, the day your NICU baby came home.

The shop is run by Blood Doctor Kelly, a hematologist-oncologist who spends her days on the other side of the desk from the people these stickers are for. The designs started as something to hand a patient at the end of a hard appointment. They turned out to be something people wanted to keep.

How the stickers are made

Every design is printed on demand as a 3″ × 3″ kiss-cut vinyl sticker, laminated and water-resistant, so it holds up on a water bottle, a laptop, or a chemo binder.

Design note: Created using a combination of AI-assisted and digital design tools, with final artwork curated, edited, and prepared for production by Reference Range.

What this shop is not

Stickers are not medical advice. If you have questions about your own labs, treatment, or diagnosis, your care team is the right place to take them.
