Biomarker levels: Florbetapir (AV45): 0.96 SUVR (normal ); Amyloid beta: 1139.00 pg/mL (normal ); Total tau: 218.40 pg/mL (normal ); Phosphorylated tau: 17.69 pg/mL (normal ). ",

  "gpt_diagnosis": "Reasoning: The MMSE score of 24 is borderline (normal range is typically 24-30), while the MoCA score of 19 suggests mild cognitive impairment (normal is ≥26). Biomarkers (Aβ, T-tau, P-tau, AV45) are normal, ruling out Alzheimer's pathology, but cognitive scores indicate impairment.  \nDiagnosis: MCI  \nConfidence: Medium (cognitive scores suggest impairment, but biomarkers are normal, and other causes of MCI cannot be ruled out without further clinical context).",
