No matter how neatly your medical record is written, if the doctor can't find the exact white blood cell count for that day during a follow-up appointment, they'll still ask you to look for that shiny photo in your album. We've seen many families where the photo was taken, but no searchable information was available.
Lab report archiving doesn't need to be perfect. Just copy the following four points into the "Laboratory" or "Visiting" notes (a full-page photo can be kept, but a text summary is essential):
Sampling date (on the report, not the date you paid; a one-day difference is common).
Item + Result + Unit (e.g., CREA 1.8 mg/dL; if there are abnormal arrows on the same screen, copy them ↑↓).
Reference range (write exactly what's printed on the report; different laboratories have different ranges, don't fill in "normal" from memory).
Related information from the same visit: a brief chief complaint + weight on that day (kg, one decimal place).
If several tubes were drawn during one visit, separate them by report number; don't merge them into "all blood tests are fine"—no one will be able to identify which report it is two weeks later.
For puppies, senior pets, and pets with chronic diseases undergoing follow-up examinations, it is recommended to add a note in the remarks section stating "Was the pet fasting? Was medication discontinued?" and link this note to the medication record (if vaccinations/deworming were performed on the same day, create a separate entry; do not cram them into the same section).
The above is a guide to record-keeping practices and does not constitute an interpretation of examination results or treatment advice. Any abnormal results should be interpreted by a licensed veterinarian.
