Sample Lab Sage Report

This is what a real Lab Sage analysis looks like. Your doctor said “everything's normal.” Here's what they missed.

Executive Summary

Your conventional lab results all fall within “normal” reference ranges. However, functional medicine optimal ranges reveal a pattern of early metabolic dysfunction and suboptimal thyroid function that conventional screening misses. Your fasting glucose is fine, but paired with elevated fasting insulin, your HOMA-IR reveals hidden insulin resistance. Your TSH is “normal” at 3.8 but functionally suboptimal, especially without Free T3 and TPO antibodies to complete the picture.

Marker-by-Marker Analysis

HOMA-IR (calculated)
2.8Concerning
Conventional: < 2.5 · Optimal: ≤ 1.0

Your fasting glucose (92) looks perfectly normal. But your fasting insulin (12.3) reveals the hidden story — your body is producing excess insulin to maintain that normal glucose. This is Stage 1 insulin resistance, often missed for years until it progresses to prediabetes.

Consider reducing refined carbohydrates and adding resistance training. Recheck fasting insulin in 90 days.
TSH
3.8 mIU/LSuboptimal
Conventional: 0.4 – 4.5 · Optimal: 1.0 – 2.0

Technically 'normal' but functionally elevated. A TSH of 3.8 often correlates with subclinical hypothyroid symptoms — fatigue, brain fog, weight gain, cold intolerance. Without Free T3, Free T4, and TPO antibodies, you're only seeing part of the thyroid picture.

Request a full thyroid panel: Free T3, Free T4, TPO antibodies, reverse T3. Discuss with your provider.
Ferritin
18 ng/mLSuboptimal
Conventional: 12 – 150 · Optimal: 40 – 100

Your ferritin is 'normal' by conventional standards but functionally depleted. Ferritin below 40 is associated with fatigue, hair loss, restless legs, and exercise intolerance — even without frank anemia. This is one of the most commonly missed findings in conventional medicine.

Consider iron-rich foods or supplementation. Recheck in 60-90 days. Rule out occult blood loss if applicable.
Vitamin D (25-OH)
28 ng/mLConcerning
Conventional: 30 – 100 · Optimal: 60 – 80

Actually below even conventional range, though borderline. Functional medicine targets 60-80 for optimal immune function, mood stability, and bone health. At 28, you're leaving significant health benefits on the table.

Supplement with D3 + K2. Typical dose: 5,000 IU/day with recheck in 90 days. Take with fat-containing meal for absorption.
hs-CRP
0.6 mg/LOptimal
Conventional: < 3.0 · Optimal: < 1.0

Excellent. Low systemic inflammation. This is a reassuring finding and suggests no major inflammatory driver at this time.

No action needed. Continue anti-inflammatory diet and lifestyle.
Fasting Glucose
92 mg/dLSuboptimal
Conventional: 65 – 99 · Optimal: 75 – 86

Within conventional range but functionally elevated. Paired with your HOMA-IR of 2.8, this suggests your pancreas is working harder than it should to maintain this glucose level.

See HOMA-IR recommendations above. This marker should improve with insulin sensitivity interventions.

Connection Patterns Detected

🔗 Metabolic–Thyroid Connection

Insulin resistance (HOMA-IR 2.8) and suboptimal thyroid function (TSH 3.8) frequently co-occur. Insulin resistance can impair T4-to-T3 conversion, and hypothyroidism slows glucose metabolism. Addressing both simultaneously is important — improving one often helps the other.

🔗 Nutrient Depletion Pattern

Low ferritin (18) + low Vitamin D (28) suggests either dietary insufficiency or absorption issues. Both are foundational nutrients that affect energy, immune function, and thyroid health. Consider gut health assessment if supplementation doesn't improve levels.

What to Actually Do About It

Request a full thyroid panel (Free T3, Free T4, TPO antibodies, reverse T3)
Supplement Vitamin D3 (5,000 IU/day with K2) — recheck in 90 days
Address ferritin with iron-rich foods or supplementation — target >40
Reduce refined carbohydrates, add resistance training for insulin sensitivity
Recheck fasting insulin and HOMA-IR in 90 days to track progress
