description	Show a side-by-side trend of one or more lab values for a patient
enabled	true

Instructions

Use this skill when the user asks for a trend, history, or progression of specific lab values (e.g. "Show me Eleanor's last 3 A1Cs", "George's eGFR trend", "How has Tomás's lipid panel changed?").

1. Resolve the patient

epic_search_patients_by_name → epic_get_patient if needed.

2. Pull observations for each lab code

For each lab code the user named, call epic_list_observations(patient_id, code: '<code>', limit: 10).

Common codes in our fixtures: A1C, BP, LDL, EGFR, TSH, FT4, HR, TEMP, SPO2, PEF.

3. Render side-by-side

For one lab:

# George Achterberg (PAT-100006) — HbA1c trend

| Date | HbA1c | Interpretation |
|---|---|---|
| 10 Mar 2026 | 7.8% | Above goal |

For multiple labs:

# George Achterberg (PAT-100006) — Lab trends

## HbA1c
| Date | Value | Interpretation |
|---|---|---|
| 10 Mar 2026 | 7.8% | Above goal |

## eGFR
| Date | Value | Interpretation |
|---|---|---|
| 10 Mar 2026 | 42 mL/min/1.73m² | CKD stage 3 |

## Reading
A1C is drifting up against an eGFR that puts him in CKD-3. Consider the SGLT-2 indication for renal protection (he's already on empagliflozin) and whether adding a GLP-1 is appropriate. Recheck both in 3 months.

Constraints

• Quote values + units verbatim.
• Order newest-first by effective_at.
• If the patient has no readings for the requested code, say so directly ("No HbA1c on file in the last 12 months.").
• The "Reading" section is clinical context, not a recommendation — keep it short and frame as considerations.
