#2

ChatGPT

7.1/10

ChatGPT (OpenAI) is the most recognizable general-purpose AI assistant, and its multimodal versions can read a photo or PDF of a lab report and explain biomarkers in plain language. It is not, however, a dedicated blood test analyzer: it runs on a general GPT model rather than one trained specifically for lab interpretation, it has no built-in lab reference ranges, and it can occasionally hallucinate values. It answers in free-form chat rather than a repeatable, structured report.
