Welcome to LabCoach!

I'm here to help you understand the biomarkers in your Fertility & Preconception Panel panel.

Try asking:

  • "What does creatinine measure?"
  • "Why is vitamin D important?"
  • "What influences glucose levels?"
This provides educational information about biomarkers—not medical advice, diagnosis, or treatment. Always consult your healthcare provider for medical concerns.

Fertility & Preconception Panel

Reproductive Hormones

Follicle-Stimulating Hormone (FSH)

general wellness biomarker
What Is It

FSH is a pituitary hormone involved in reproductive function. In women it supports follicle development; in men it supports sperm production.

What It Measures

A laboratory biomarker measured from your sample.

Why It Matters

This marker can provide educational insight into general wellness domains such as metabolism, nutrient status, organ function, inflammation, or hormonal signaling. Interpretation depends on context, symptoms, medications, and timing.

Common Influences
  • Recent illness or inflammation
  • Medications and supplements
  • Hydration status
  • Fasting status and time of day
  • Recent exercise and stress

Luteinizing Hormone (LH)

general wellness biomarker
What Is It

LH is a pituitary hormone that helps regulate reproductive function. In women it helps trigger ovulation; in men it signals the testes to produce testosterone.

What It Measures

A laboratory biomarker measured from your sample.

Why It Matters

This marker can provide educational insight into general wellness domains such as metabolism, nutrient status, organ function, inflammation, or hormonal signaling. Interpretation depends on context, symptoms, medications, and timing.

Common Influences
  • Recent illness or inflammation
  • Medications and supplements
  • Hydration status
  • Fasting status and time of day
  • Recent exercise and stress

Estradiol (E2)

reproductive signaling bone health cardiovascular support
What Is It

Estradiol (E2) is a primary estrogen hormone. It supports reproductive function and also plays roles in bone, cardiovascular, brain, and skin health in both women and men.

What It Measures

Estradiol (a primary estrogen).

Why It Matters

Used in wellness education around reproductive hormones and overall hormone balance; timing matters for cycling individuals.

Common Influences
  • Menstrual cycle phase
  • Hormonal medications
  • Body fat level
  • Alcohol
  • Liver function

Progesterone (Day 21 level)

cycle regulation reproductive signaling neurosteroid effects
What Is It

Progesterone is a reproductive hormone that rises after ovulation and supports the menstrual cycle and pregnancy-related physiology. Timing within the cycle affects interpretation.

What It Measures

Progesterone (a reproductive hormone).

Why It Matters

Provides context for cycle phase and ovulation timing when measured appropriately; interpret with a provider.

Common Influences
  • Cycle phase
  • Pregnancy
  • Hormonal medications
  • Stress and energy availability
  • Timing of collection

Prolactin

general wellness biomarker
What Is It

Prolactin is a pituitary hormone best known for its role in lactation, but it also interacts with reproductive hormone signaling in both women and men.

What It Measures

A laboratory biomarker measured from your sample.

Why It Matters

This marker can provide educational insight into general wellness domains such as metabolism, nutrient status, organ function, inflammation, or hormonal signaling. Interpretation depends on context, symptoms, medications, and timing.

Common Influences
  • Recent illness or inflammation
  • Medications and supplements
  • Hydration status
  • Fasting status and time of day
  • Recent exercise and stress

Testosterone, Total

muscle support bone health libido and vitality
What Is It

Testosterone is a sex hormone produced primarily by the testes in men and the ovaries/adrenal glands in women. It supports muscle, bone, libido, mood, and overall vitality.

What It Measures

Total testosterone concentration in blood.

Why It Matters

Used in performance, body composition, and wellness education; interpret with SHBG and free/bioavailable when available.

Common Influences
  • Time of day (often highest in morning)
  • Sleep
  • Body fat level
  • Alcohol
  • Certain medications
Thyroid & Metabolism

TSH (Thyroid Stimulating Hormone)

metabolic regulation energy balance temperature regulation
What Is It

TSH is a hormone made by the pituitary gland that signals the thyroid to produce thyroid hormones. It is part of the feedback system that helps regulate metabolism and energy.

What It Measures

Pituitary signal that helps regulate thyroid hormone production.

Why It Matters

Supports thyroid wellness education when interpreted alongside Free T4, Free T3, and symptoms with a clinician.

Common Influences
  • Illness/stress
  • Thyroid medication
  • Iodine status
  • Autoimmunity
  • Pregnancy

Free T4 (Thyroxine)

general wellness biomarker
What Is It

Free T4 is the unbound (active-available) form of thyroxine, one of the main thyroid hormones. The body can convert T4 into T3, the more active thyroid hormone.

What It Measures

Unbound thyroxine available in blood.

Why It Matters

Provides context for thyroid hormone availability; best interpreted with TSH and Free T3.

Common Influences
  • Thyroid medication
  • Illness
  • Iodine intake
  • Pregnancy
  • Certain supplements (biotin)
Key Nutrients

Vitamin D, 25-Hydroxy (Total)

bone metabolism immune support calcium regulation
What Is It

Vitamin D is a fat-soluble vitamin important for bone and immune function. 25‑hydroxy vitamin D is the standard blood marker used to estimate vitamin D status.

What It Measures

25-hydroxy vitamin D, the standard marker of vitamin D status.

Why It Matters

Supports education around bone, immune, and overall wellness. Seasonal changes and supplementation can affect levels.

Common Influences
  • Sun exposure
  • Supplement use
  • Body fat levels
  • Season/geography
  • Certain medications

Folate (Folic Acid), Serum

general wellness biomarker
What Is It

Folate is a B‑vitamin important for DNA synthesis and red blood cell production. It works closely with vitamin B12 in one‑carbon (methylation) metabolism.

What It Measures

Folate status in blood.

Why It Matters

Supports education around methylation pathways and red blood cell health; works closely with B12.

Common Influences
  • Dietary leafy greens/fortified foods
  • Supplement use
  • Alcohol intake
  • Certain medications
  • Gut absorption

Vitamin B12 (Cobalamin)

red blood cell formation nerve function energy metabolism
What Is It

Vitamin B12 is a water-soluble vitamin important for red blood cell formation, nerve health, and energy metabolism. Cobalamin is the primary form measured in blood.

What It Measures

Vitamin B12 status in blood.

Why It Matters

Used in wellness education around energy metabolism, nerve support, and red blood cell formation.

Common Influences
  • Dietary intake (animal foods)
  • Supplement use
  • Absorption issues
  • Medications (e.g., metformin)
  • Bariatric surgery history
