Validation Checks

1. Numeric Data Completeness

Every numeric value in extracted.md must appear in final_analysis.md

Extract and verify:

• Lab values (e.g., "Hemoglobin 14.6 g/dL")
• Reference ranges (e.g., "Reference: 12.0-16.0")
• Dates (e.g., "Test date: 2024-03-15")
• Vitals (e.g., "Blood pressure 120/80")
• Dosages (e.g., "Metformin 500mg twice daily")
• Ages, weights, measurements

Example flags:

❌ MISSING NUMBER: Hemoglobin 14.6 g/dL - not found in analysis
❌ MISSING DATE: Test date March 15, 2024 - not mentioned
✓ FOUND: Neutrophils 1.2 - appears in Critical Findings
✓ FOUND: Reference range 2.0-7.5 - correctly cited

---

2. Qualitative Data Completeness

Every non-numeric fact in extracted.md must be accounted for

Extract and verify ALL of these categories:

A. Symptoms & Complaints

• Patient-reported symptoms ("fatigue", "joint pain", "brain fog")
• Duration of symptoms ("for 3 months")
• Severity descriptions ("severe", "mild", "intermittent")
• Symptom patterns ("worse in the morning")

Example flags:

❌ MISSING SYMPTOM: Patient reported "chronic fatigue for 6 months" - not mentioned
❌ MISSING DETAIL: "Pain worse after eating" - context lost
✓ FOUND: "Joint stiffness" - appears in patient history section

B. Medical History

• Past diagnoses ("history of hypothyroidism")
• Previous conditions ("had COVID in 2022")
• Surgeries ("appendectomy 2019")
• Family history ("mother has diabetes")
• Allergies ("allergic to penicillin")

Example flags:

❌ MISSING HISTORY: "History of Hashimoto's thyroiditis" - critical context omitted
❌ MISSING FAMILY HISTORY: "Father had heart attack at 55" - relevant to cardiovascular findings
✓ FOUND: "Previous diagnosis of anemia" - mentioned in context

C. Current Medications & Supplements

• Prescription medications (name, dose, frequency)
• Over-the-counter medications
• Supplements and vitamins
• Recent medication changes

Example flags:

❌ MISSING MEDICATION: "Currently taking Levothyroxine 50mcg" - affects thyroid interpretation
❌ MISSING SUPPLEMENT: "Taking B12 injections monthly" - critical for B12 level interpretation
✓ FOUND: "Metformin 500mg twice daily" - mentioned in medication context

D. Lifestyle & Context Factors

• Diet information ("vegetarian", "keto diet")
• Exercise habits
• Sleep patterns
• Stress factors mentioned
• Occupation if relevant
• Recent life changes

Example flags:

❌ MISSING CONTEXT: "Patient is vegan" - explains B12/iron findings
❌ MISSING CONTEXT: "Works night shifts" - affects cortisol interpretation
✓ FOUND: "High stress job" - mentioned in lifestyle factors

E. Doctor's Notes & Comments

• Physician observations
• Clinical impressions from source documents
• Recommended follow-ups in original documents
• Flagged concerns from ordering physician

Example flags:

❌ MISSING NOTE: Ordering physician noted "rule out autoimmune" - important context
✓ FOUND: Doctor's comment about concerning trend included

---

3. Calculation & Interpretation Accuracy

Verify all calculated values and interpretations

A. Percentage Changes

When the analysis says "increased 85%":

• Find both values (before and after)
• Calculate: (new - old) / old × 100
• Verify the stated percentage

B. Trend Descriptions

When the analysis says "declining trend":

• Verify multiple data points exist
• Confirm the direction is correct
• Check if trend description matches data

C. Status Labels

When the analysis says "critically low":

• Find the reference range
• Verify the value is actually in that category
• Check terminology accuracy (low vs. critically low vs. deficient)

D. Comparative Statements

When the analysis says "twice the normal limit":

• Calculate actual ratio
• Verify the comparison is accurate

Example flags:

❌ CALCULATION ERROR: "Homocysteine increased 50%" - actual increase is 85% (10.4 → 19.24)
❌ WRONG INTERPRETATION: "TSH is elevated" - TSH 3.07 is within normal range 0.35-4.5
❌ EXAGGERATION: "Extremely high cholesterol" - value 220 is only mildly elevated
✓ CORRECT: "Neutrophils critically low at 1.2" - well below reference 2.0-7.5

---

4. Claim Support Check

Every clinical claim must have supporting evidence

Types of claims to verify:

A. Diagnostic Statements

• "You have X condition" - Is there diagnostic criteria met?
• "This indicates Y" - Is the indication supported?

B. Causal Claims

• "X is causing Y" - Is there evidence for causation, or just correlation?
• "This is due to Z" - Is the mechanism supported by data?

C. Prognostic Statements

• "This will likely improve" - Based on what evidence?
• "Risk of developing X" - Is risk quantified in data?

D. Hypotheses vs. Facts

• Hypotheses should be labeled as such
• Speculation should be acknowledged
• Certainty language should match evidence level

Example flags:

❌ UNSUPPORTED DIAGNOSIS: "You have lupus" - no lupus-specific markers in data
❌ UNSUPPORTED CAUSATION: "Stress is causing your symptoms" - no stress markers tested
❌ UNMARKED HYPOTHESIS: "Malabsorption is the cause" stated as fact, should be hypothesis
⚠️ OVERCLAIMED: "Definitely autoimmune" - RF positive but anti-CCP negative, not definitive
✓ WELL SUPPORTED: "Neutropenia present" - value 1.2, ref 2.0-7.5, clearly meets criteria
✓ PROPERLY HEDGED: "Possibly suggests malabsorption" - appropriately marked as hypothesis

---

5. Context Preservation Check

Critical context must not be lost in synthesis

Verify that important contextual information flows through:

A. Medication-Lab Interactions

• If patient takes medication X, and lab Y is affected by X, this context should be mentioned
• Example: "Patient on biotin supplements" should appear when discussing biotin-affected labs

B. Temporal Context

• When were tests done?
• Are there multiple time points being compared?
• Is the timeline clear?

C. Conditional Context

• "Fasting sample" vs "non-fasting"
• "Post-exercise" measurements
• "During illness" vs "baseline"

D. Patient-Specific Context

• Age-appropriate interpretations
• Gender-specific reference ranges used correctly
• Pregnancy status if applicable

Example flags:

❌ LOST CONTEXT: Analysis interprets low B12 without mentioning patient takes metformin (which depletes B12)
❌ LOST CONTEXT: Cholesterol interpreted without noting "non-fasting sample"
❌ LOST CONTEXT: Elevated WBC flagged as concerning without noting "patient had cold last week"
✓ CONTEXT PRESERVED: "Elevated liver enzymes may be related to recent alcohol use mentioned by patient"

---

6. Internal Consistency Check

No contradictions within the analysis

Look for:

A. Value Contradictions

• Same marker with different values in different places
• Inconsistent units

B. Status Contradictions

• "Thyroid is normal" in one place, "thyroid dysfunction" in another
• "Critical" vs "mild concern" for same finding

C. Recommendation Contradictions

• Recommending conflicting actions
• Urgency levels that don't match findings

D. Narrative Contradictions

• "Overall healthy" but "multiple critical findings"
• Tone mismatches

Example flags:

❌ VALUE MISMATCH: Homocysteine listed as 19.24 in findings but 19.4 in summary
❌ STATUS CONTRADICTION: Says "thyroid is fine" in overview but "thyroid stress evident" in details
❌ URGENCY MISMATCH: Lists as "routine follow-up" but has critical neutropenia
✓ CONSISTENT: All mentions of neutropenia use value 1.2 and "critical" status

---

7. Recommendation Traceability Check

Every recommendation must tie to a specific finding

Verify:

• Each supplement recommendation → specific deficiency documented
• Each "see specialist" recommendation → specific concerning finding
• Each test recommendation → specific uncertainty to resolve
• Each lifestyle recommendation → specific relevant finding

Example flags:

❌ UNTRACEABLE: "Consider stress management" - no stress markers or cortisol in data
❌ UNTRACEABLE: "Take vitamin D" - no vitamin D level was tested
❌ WEAK LINK: "See cardiologist" - only finding is mildly elevated homocysteine, may be excessive
✓ TRACEABLE: "Start zinc 15-30mg" - zinc 585, ref 660-1100, documented deficiency
✓ TRACEABLE: "See hematologist urgently" - neutrophils 1.2, critically low, appropriate referral

---

8. Patient Question Relevance Check

If the patient asked a specific question, verify it's addressed

When patient asks "What's causing my fatigue?":

• Does the analysis identify potential causes from the data?
• Are fatigue-related findings prominently featured?
• Is there a clear answer or explanation of why we can't answer yet?

When patient asks "Should I be worried about X?":

• Is X specifically addressed?
• Is the concern validated or alleviated with evidence?

Example flags:

❌ QUESTION IGNORED: Patient asked "Why am I so tired?" - fatigue not addressed despite low iron
❌ QUESTION PARTIALLY ADDRESSED: Asked about thyroid, only briefly mentioned
✓ QUESTION ADDRESSED: Patient asked about B12, analysis dedicates section to B12 status and implications
✓ QUESTION ADDRESSED: Asked "Am I at risk for diabetes?" - glucose and HbA1c specifically discussed
