Biomarker levels: Florbetapir (AV45): 0.98 SUVR (normal ); Amyloid beta: 1446.00 pg/mL (mild elevated); Total tau: 251.40 pg/mL (normal ); Phosphorylated tau: 22.11 pg/mL (normal ). ",

  "gpt_diagnosis": "Reasoning: The MMSE score of 30.0 is within the normal range, and the MoCA score of 26.0 is borderline but still within normal limits for cognitive screening. Biomarkers show mild Aβ elevation but normal tau and AV45, suggesting minimal amyloid pathology without significant neurodegeneration.  \n\nDiagnosis: **CN (Cognitively Normal)**  \nConfidence: **Medium** (due to borderline MoCA and mild Aβ elevation, but overall clinical and biomarker profile does not suggest impairment)",
