Thyroid Hormone & Thyroid Disease Testing

Introduction: Why Thyroid Disorders Need a New Diagnostic Approach

Thyroid disorders are some of the most underdiagnosed and mismanaged hormonal conditions today. At Patients Medical in New York City, we believe thyroid health isn’t just about your TSH level. We look deeper—testing the full hormone cascade, identifying autoimmune triggers, and exploring the root causes of imbalance using a functional medicine lens.

If you’re dealing with unexplained fatigue, weight changes, hair thinning, mood swings, or fertility struggles—your thyroid could be the missing link.

Understanding the Thyroid: Your Metabolic Master Gland

The thyroid is a butterfly-shaped gland located at the base of your neck. It produces hormones—mainly T4 (thyroxine) and T3 (triiodothyronine)—that regulate metabolism, energy, brain function, and body temperature.

Common Thyroid Conditions We Evaluate
  • Hypothyroidism: Underactive thyroid; most common cause is Hashimoto’s thyroiditis (autoimmune).
  • Hyperthyroidism: Overactive thyroid; often caused by Graves’ disease (autoimmune).
  • Subclinical Hypothyroidism: Normal TSH, but poor T3/T4 conversion and symptoms.
  • Thyroid Nodules or Goiter: Enlargement or abnormal growths in the gland.
  • Postpartum Thyroiditis: Temporary thyroid dysfunction following pregnancy.

Common Signs of Thyroid Dysfunction

Many thyroid issues go undiagnosed for years due to incomplete testing. Symptoms include:

What’s Causing Your Thyroid Imbalance?

Functional medicine digs deep into the root causes of thyroid dysfunction. Here’s what we look for:

  • Autoimmunity (e.g., Hashimoto’s or Graves’)
  • Leaky gut and food sensitivities
  • Chronic infections (like EBV)
  • Nutrient deficiencies (iodine, selenium, zinc, iron, B12)
  • Adrenal dysfunction and stress overload
  • Toxin exposure (fluoride, mercury, BPA)
  • Estrogen dominance or hormonal imbalance
  • Impaired liver detox (affects T4–>T3 conversion)

Comprehensive Thyroid Testing at Patients Medical

We offer a complete and advanced panel—not just TSH. Your labs may include:

TSH – Thyroid-stimulating hormone

Free T3 and Free T4 – Active and circulating thyroid hormones

Reverse T3 – Inactive hormone that competes with T3

Thyroid Antibodies – TPO-Ab and TG-Ab to detect autoimmune thyroiditis

TRAb and TSI – For Graves’ disease evaluation

Iodine and Selenium levels

Cortisol and adrenal profile

Micronutrient panel (zinc, magnesium, iron, B12, vitamin D)

Integrative Thyroid Treatments

Nutritional & Lifestyle Therapy

  • Anti-inflammatory, gluten-free, and low-glycemic diets
  • Selenium, iodine (as appropriate), and iron-rich meal plans
  • Elimination diets for food sensitivity discovery
  • Natural detox protocols to reduce toxic burden

Personalized Hormone Therapy

  • Natural Desiccated Thyroid (NDT) for T4/T3 combination
  • T3-Only Protocols for conversion issues
  • Compounded Options for precise dosing

Autoimmune Stabilization

  • Gluten-Free/Grain-Free Diet (based on Cyrex Array 3 testing)
  • Low-Dose Naltrexone (LDN) to modulate immune response
  • IV Glutathione to reduce thyroid antibody levels

Gut-Thyroid Repair

  • H. pylori Eradication (linked to Hashimoto’s)
  • Probiotic Protocols (L. reuteri improves TSH levels)
  • Leaky Gut Healing (bone broth, colostrum, zinc carnosine)

Metabolic Optimization

  • Mitochondrial Support (CoQ10, PQQ, B vitamins)
  • Adaptogens (ashwagandha for cortisol balance)
  • Detox Protocols (selenium for mercury chelation)

Real Patient Story: Samantha’s Thyroid Comeback

Samantha, age 34, came in with weight gain, depression, and irregular periods. Her TSH was “normal” but she still felt off. We ran a full thyroid panel and discovered Hashimoto’s with elevated antibodies, low Free T3, and poor adrenal function.

Her custom treatment plan included:

  • Gluten-free, anti-inflammatory diet
  • Selenium and zinc supplementation
  • Bioidentical T3/T4 thyroid support
  • Gut healing with probiotics and L-glutamine
  • Adrenal herbs and stress coaching

Result: Within 12 weeks, Samantha’s energy returned, her cycles regulated, and her antibodies began to drop.

Frequently Asked Questions

 TSH is a starting point but often misses deeper issues like low Free T3 or autoimmunity.

 Yes. Many patients have “normal” TSH but abnormal Free T3, high antibodies, or poor conversion rates.

Yes. We use Armour, NP Thyroid, compounded T3/T4, and others as needed.

 It’s not curable, but we can often reduce antibodies and control symptoms naturally.

 Absolutely. Diet is a major part of thyroid healing—especially gluten-free and anti-inflammatory approaches.

 Only if tested and monitored—excess iodine can worsen autoimmunity.

 Yes. Stress and cortisol imbalance often suppress thyroid function.

 Free T3 is active; Reverse T3 is inactive and blocks Free T3. High rT3 may signal stress or illnes.

 We are an out-of-network provider but offer superbills. Many lab tests may be reimbursable.

 Some notice improvements within weeks. Deeper healing may take 2–4 months.
