Biomarker levels: Florbetapir (AV45): 1.06 SUVR (normal ); Amyloid beta: 769.00 pg/mL (normal ); Total tau: 153.80 pg/mL (mild reduced); Phosphorylated tau: 13.63 pg/mL (mild reduced). ",

  "gpt_diagnosis": "Reasoning: The MMSE score of 28 is within the normal range, and the MoCA score of 24 is slightly below the typical cutoff of 26, suggesting possible mild cognitive impairment (MCI). However, amyloid (Aβ) and AV45 (a marker for amyloid plaques) are normal, and tau biomarkers (T-tau, P-tau) are mildly reduced, which does not strongly support Alzheimer's pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to borderline MoCA but normal biomarkers and high MMSE)",
