Your cat's blood test report: organize questions, not self-diagnoses

Unfamiliar abbreviations or a mark outside a reference interval can be worrying. Keep the original report first, then turn uncertainties into questions. This article does not interpret test values. If a change in your cat's condition concerns you, contact a veterinary clinic without waiting to finish reading.

An editorial guide to keeping reports and preparing questions, based on public resources from veterinary institutions and organizations. It is not veterinarian-reviewed and does not diagnose or interpret results. Ask your veterinarian about your cat's findings. The illustration does not depict a particular cat or test result.

01

Keep the whole report legible

Keep a photo or copy with the cat's name, date, laboratory, test names, results, units and printed reference intervals visible together. If you make a transcription, retain enough detail to compare every symbol and decimal with the original. Avoid cropped images or file names that could mix up cats.

  • Distinguish each cat and date when keeping current and prior reports
  • Keep the printed units and interval with each test name
  • Record only known facts about the visit, medicines or food separately
02

A reference interval is not a universal pass/fail line

Laboratory guidance explains that intervals can depend on the analyzer, method and reagents, and results can vary with age. Do not apply a number from another website directly to your cat's report. A single flag does not make a diagnosis; ask the treating veterinarian what it means in the context of your cat and the full test panel.

  • Use the units and interval printed on this report
  • Ask whether the laboratory or method changed since the prior test
  • Tell the veterinarian about age, treatment and other relevant context
03

Importance cannot be ranked by flag color or count alone

Veterinarians consider bloodwork with the history, examination and earlier results. A report from a cat with symptoms has a different context from a routine wellness check. Rather than ranking one value yourself, ask which finding the veterinarian is focusing on first and why.

  • Do not connect a searched abbreviation directly to a disease
  • Share appetite, drinking, toileting or movement changes with dates
  • Ask whether another test or follow-up is needed to interpret the result
04

Compare with prior reports together

Earlier results can help the veterinary team understand what is typical for this cat. A rise or fall alone does not prove disease or improvement: ask whether timing, health, treatment and measurement conditions are comparable. Plan any follow-up interval with the veterinarian around age, history and current condition.

  • Which earlier report is being used for comparison?
  • Are the laboratory, test, method and units comparable?
  • What should be noted before the next visit, and what is its purpose?
05

Take these five questions to the appointment

It is fine not to absorb everything at once. Point to the relevant part of the report and separate what is known, what remains uncertain and what happens next. If cost or travel is difficult, say so and ask about options.

  • Given my cat's condition today, which findings are the priority and why?
  • How do you consider these results alongside symptoms and the examination?
  • What changed—or stayed the same—compared with the prior report?
  • Is any additional check needed, and why?
  • Can you explain the next step, when to call, and the follow-up plan in a form I can note?
06

Choose a private place for your own notes

You can copy the blank template below to your own device or paper. This page has no form for entering, submitting or storing records. Reports may contain names, contact details or clinic information. Do not post originals in public comments or social media; ask the clinic how to share them safely.

  • Check sharing settings wherever report photos or PDFs are stored
  • When sharing with family, pass on the veterinarian's explanation, not a guessed diagnosis
  • If you are worried about a change, contact the clinic before making notes
