Related similar thing when I sent my dog's recent bloodwork to an LLM, including dates, tests, and values. The model suggested that an advancement in her kidney values (all still within normal range) were likely evidence of chronic kidney disease in its early stage. Naturally this caused some concern for my wife.

But, I work in healthcare and have enough knowledge of health to know that CKD almost certainly could not advance fast enough to be the cause of the kidney value changes in the labs that were only 6 weeks apart. I asked the LLM if that's the best explanation for these values given they're only 6 weeks apart, and it adjusted its answer to say CKD is likely not the explanation as progression would happen typically over 6+ months to a year at this stage, and more likely explanations were nephrotoxins (recent NSAID use), temporary dehydration, or recent infection.

We then spoke to our vet who confirmed that CKD would be unlikely to explain a shift in values like this between two tests that were just 6 weeks apart.

That would almost certainly throw off someone with less knowledge about this, however. If the tests were 4-6 months apart, CKD could explain the change. It's not an implausible explanation, but it skipped over a critical piece of information (the time between tests) before originally coming to that answer.
