Evaluation of causal reasoning for large language models in contextualized clinical scenarios of laboratory test interpretation

Advanced AI shows meaningful but incomplete causal reasoning for lab test interpretation, highlighting gaps before clinical deployment.

GPT-o1 demonstrated superior causal reasoning on 99 clinical lab test scenarios (AUROC 0.80) compared to Llama-3.2-8b (0.73), with intervention reasoning better than counterfactual reasoning for both models. This benchmarking study reveals important capability gaps limiting LLM deployment for clinical laboratory decision support.
