Needs a look Two kidney results 100 days apart are in the G3b range (filtering rate 37.5 on 2026-08-04 and 34.7 on 2026-11-12); the note doesn't mention kidney function.

The note unsigned draft · Thu Nov 12, 2026 02:00 PM

Chief complaint: follow-up of thyroid condition and fatigue.
History of present illness: The patient states that her energy has improved since the last dose change. She reports good adherence to levothyroxine and denies palpitations.
Review of systems: Negative except as noted.
Assessment and plan: 1. Hypothyroidism, improving. Continue the current dose and recheck TSH in eight weeks. 2. Fatigue, improving. Encourage regular sleep schedule.

The results

The note is compared with the patient's own measurements, in both directions. Kidney filtering rate (eGFR) is estimated from creatinine, age and sex.

Kidney function over time Needs a look

2026-08-04 creatinine 1.5 mg/dL · filtering rate 37.5 (G3b range)
2026-11-12 creatinine 1.6 mg/dL · filtering rate 34.7 (G3b range)

Threshold: filtering rate below 60 on two results at least 90 days apart, none of 60 or more between them.

Mode: measurements only (no diagnosis is named). The check runs the same way on clinician-typed and AI-drafted notes (as declared by the source system).

Kidney function (eGFR persistence) · kdigo_ckd_2024@1.1

eGFR: Labs meet the criteria; nothing documented criteria met under 2 of 2 eGFR equations (2021 race-free, 2009)

eGFR 34.7 on 2026-11-12 (lab row L-0017) and eGFR 37.5 on 2026-08-04 (lab row L-0016), 100 days apart, no value >= 60 between. KDIGO persistence: met. Persistent GFR category G3b (the range both values meet). Note: no kidney-function statement found.

Both directions
What the labs show that the note doesn't say	Criteria met; no statement in the note
What the note says that the labs don't support	No statement in the note

not met: Urine ACR >= 30 mg/g on two values at least 90 days apart (needed only when eGFR >= 60) (kdigo_ckd_2024@1.1)
no urine ACR on file
met: Latest creatinine below 1.5x the lowest value in the previous 365 days (otherwise: possible acute change; repeat needed) (kdigo_ckd_2024@1.1)
1.6 / 1.5 = 1.07x
Rows: L-0016, L-0017
met: No condition on record that makes the estimating equation unreliable (maintenance dialysis, kidney transplant, pregnancy, limb amputation or another extreme of muscle mass) (kidney_exclusions@1.0)
none on record for this encounter date
met: Two eGFR < 60 at least 90 days apart, none >= 60 between (2009 eGFR equation) (kdigo_ckd_2024@1.1)
pair L-0016 (35.2, 2026-08-04) and L-0017 (32.5, 2026-11-12), 100 days apart; persistent category G3b (the range both values meet)
Rows: L-0016, L-0017
met: Two eGFR < 60 at least 90 days apart, none >= 60 between (2021 eGFR equation) (kdigo_ckd_2024@1.1)
pair L-0016 (37.5, 2026-08-04) and L-0017 (34.7, 2026-11-12), 100 days apart; persistent category G3b (the range both values meet)
Rows: L-0016, L-0017
met: Values used are steady-state (local convention: values from an admission meeting the creatinine-change criteria are excluded) (kdigo_ckd_2024@1.1)
no values excluded

Creatinine change during this admission · kdigo_aki_2012@1.1

Creatinine change: Does not apply to this visit

Not assessed: outpatient visit: the creatinine-change check runs on inpatient encounters only.

Try one creatinine value

One value is never a confirmed stage: the persistence rule needs a repeat at least 90 days later.
