3. Trend Analysis
When the user has multiple data points for the same marker, perform trend analysis:
Plot values over time against the reference range, noting where values fall within the range (low-normal, mid-range, high-normal, out-of-range).
Flag the following conditions:
Out-of-range values (above or below reference range)
Significant changes: greater than 20% shift between consecutive tests
Trending toward boundary: value moving consistently toward upper or lower limit across 3+ data points
Rapid changes that may warrant earlier retesting
Unit conversion support:
Testosterone: ng/dL to nmol/L (multiply by 0.0347)
Estradiol: pg/mL to pmol/L (multiply by 3.671)
Cortisol: mcg/dL to nmol/L (multiply by 27.59)
Vitamin D: ng/mL to nmol/L (multiply by 2.496)
TSH: mIU/L = mcIU/mL (equivalent)
Present trends in table format with directional arrows and percentage change between consecutive readings.
4. Symptom-Hormone Correlation
Track symptoms alongside lab values to identify potential correlations. When recording symptoms, note date, severity (1-10), and frequency.
Thyroid-Related Symptoms
Fatigue / low energy
Unexplained weight gain or loss
Hair loss or thinning
Cold intolerance (hypothyroid) or heat intolerance (hyperthyroid)
Resting heart rate changes (bradycardia or tachycardia)
Nature exposure -- Emerging evidence for cortisol and DHEA improvement
Social connection -- Moderate evidence for oxytocin and cortisol modulation
Limit caffeine after 12pm -- Moderate evidence for cortisol rhythm preservation
Supplements (discuss with provider before starting)

6. Hormone Health Score (0-100)
Calculate a composite hormone health score using three weighted components:
Component Breakdown
Lab Values In Range -- 40% of total score
For each tracked marker: score 100 if within optimal range, 75 if within standard reference range, 50 if borderline (within 10% of range boundary), 25 if mildly out of range (within 20% beyond boundary), 0 if significantly out of range
Average across all tracked markers, weighted by clinical significance
Symptom Burden -- 30% of total score
Based on symptom severity ratings (1-10 scale) across all tracked symptoms
Score = 100 - (average symptom severity x 10)
Weighted by number of hormone-related symptoms reported
Lifestyle Factors -- 30% of total score
Sleep quality and duration: 0-25 points
Exercise frequency and type: 0-25 points
Nutrition quality: 0-25 points
Stress management practices: 0-25 points
Score Interpretation
Score Range
Interpretation
85 - 100
Excellent -- hormones well-optimized
70 - 84
Good -- minor areas for improvement
55 - 69
Fair -- several areas need attention
40 - 54
Below average -- significant optimization opportunities
0 - 39
Poor -- recommend comprehensive evaluation with endocrinologist
7. Testing Schedule Recommendations
Thyroid
On thyroid medication (levothyroxine, etc.): Retest TSH and Free T4 every 6-8 weeks after dose changes, then every 6-12 months once stable
Stable, no medication: Annual thyroid panel
Hashimoto's or Graves' disease: TSH, Free T4, Free T3, and antibodies every 6 months
Timing: Fasting, morning draw preferred; hold thyroid medication until after blood draw
Sex Hormones (Female)
Fertility evaluation: Day 3 (FSH, LH, Estradiol) and Day 21 (Progesterone) of cycle
PCOS workup: Total and free testosterone, DHEA-S, fasting insulin, LH/FSH ratio -- any cycle day
Perimenopause/menopause symptoms: FSH, Estradiol, tested during early follicular phase if still cycling
On HRT: Retest 6-8 weeks after starting or dose change, then every 6-12 months
Sex Hormones (Male)
Initial low-T evaluation: Total testosterone, free testosterone, SHBG, LH, FSH, estradiol, prolactin -- fasting AM draw (before 10am)
On TRT: Total and free testosterone, estradiol, hematocrit, PSA every 3-6 months initially, then every 6-12 months
Monitoring: Always draw between 7-10am for consistency
Cortisol
Serum cortisol: Must be drawn between 7-9am for AM cortisol

Clinical Context Matters
Reference ranges vary by laboratory, assay method, age, sex, time of day, and individual factors. The ranges listed in this skill are general guidelines only.
A single lab value rarely tells the full story. Patterns over time and symptom correlation are more informative than isolated readings.
Subclinical findings (values technically in range but at the extremes) may be clinically significant in the context of symptoms.
