Thyroid Testing Blood Work: The Extensive Profile with Antibodies & Reverse T3

Your thyroid is often the hidden key to mood, energy, and mental health. It sets the idle speed of your body and brain — too slow and you feel flat, foggy, and depressed; too fast and you’re anxious, restless, and can’t switch off. Yet standard thyroid checks often miss the early signs.

At BalanSoul, our Extensive Thyroid Profile goes beyond a basic TSH screen. Instead of a single snapshot, it measures TSH, Free T4, Free T3, Reverse T3, and antibodies (TPOAb, TgAb; TRAb if indicated) — giving us the full story of how your thyroid is performing, whether it’s under immune attack, and how well your body is converting hormones into its active form.

Why does this matter? Because:

  • Many labs still report a broad “normal” TSH range of 0.5–5.0, but research and functional medicine experience show an optimal window of 0.5–2.0.Symptoms often begin inside this narrower range, long before standard labs flag an issue.
  • Reverse T3 acts like a hormonal brake.In times of stress or illness, the body may divert T4 into rT3 instead of Free T3, leaving you with hypothyroid symptoms even when bloodwork looks “normal.”

This page will show you how hidden thyroid patterns can drive depression, anxiety, fatigue, and insomnia — and how BalanSoul identifies these shifts early, so you can act before they become life-altering.

Why this test matters for mental health

Your thyroid isn’t just about metabolism — it’s deeply tied to how you feel, think, and cope with life. When it drifts off course, mood often follows.

👉 At BalanSoul, we don’t look at numbers in isolation. We weave results into your personal story — because your mental health isn’t just a lab value, it’s the day-to-day dance between body and brain.

Why serum (blood) testing — and why go “extensive"

Most doctors order a basic thyroid screen — usually TSH, sometimes with Free T4. That’s a useful start, but it can miss the bigger picture.

  • Early autoimmunity:Antibodies (TPOAb, TgAb) can quietly attack the thyroid for years before hormones change enough for a diagnosis. Catching this early means you can act sooner, not wait until damage is advanced.
  • Graves’ overstimulation:In some cases, antibodies (TRAb) can “push” the thyroid into overdrive, leading to hyperthyroid symptoms like anxiety, agitation, and poor sleep.

 

Our Extensive Thyroid Profile includes these markers so we can spot patterns that are often missed — and intervene earlier, especially when mood and cognition are affected.

Why BalanSoul needs to understand your thyroid pattern

At BalanSoul, we don’t stop at asking “is it high or low?” Thyroid health is more like a map with crossroads:

  • TSH shows how hard your brain is pushing.
  • T4 shows supply.
  • T3 shows activation.
  • rT3 reveals when stress has pushed you onto a detour.
  • Antibodies uncover if your immune system is waging a quiet war.

Each marker is part of the story. Together they explain why you feel flat, foggy, anxious, or “wired but tired.” With this map, we build a plan that supports mood, sleep, and energy while working alongside your GP if medication is needed.

Common thyroid patterns that affect mood

Thyroid issues often whisper through mood and energy before showing up in routine labs. Three patterns we often see:

  • Hashimoto’s / Hypothyroid trend:The immune system attacks the thyroid, TSH climbs, and active hormone (T3/T4) falls. It feels like someone has turned your switch to “low” — low mood, brain fog, fatigue. Research confirms overt hypothyroidism is strongly linked to depression, and treatment often restores brighter mood.
  • Graves’ / Hyperthyroid trend:The thyroid is in overdrive. TSH plummets while T3 and T4 surge. Life feels like being stuck with your foot on the accelerator: anxiety, racing thoughts, irritability, insomnia. Studies confirm these mental health effects are common at diagnosis, but with the right support, balance can return.
  • High rT3 / low FT3:rT3 ratio:Stress sometimes diverts thyroid hormone into reverse T3 — like fuel that looks fine on the gauge but won’t ignite in the engine. This can mimic hypothyroid symptoms (tired, sluggish, foggy) even when standard labs look “normal.”

💡 Note: The evidence around subclinical thyroid shifts (borderline labs) is mixed. Some studies link them to mood symptoms, others don’t. At BalanSoul, we always interpret your results in the context of how you actually feel.

Panels / Pricing

Extensive Thyroid Profile (with antibodies & Reverse T3)

  • Price:$171
  • Markers included:TSH, Free T4, Free T3, Reverse T3, Thyroid Antibodies (TPOAb, TgAb; TRAb if indicated)
  • Why it matters:This profile goes far beyond a basic TSH screen. By checking conversion (FT3, rT3) and autoimmunity (antibodies), it can reveal thyroid imbalances long before a standard test would. These are often the missing pieces behind fatigue, low mood, anxiety, brain fog, and poor sleep — and catching them early means you can act sooner.

Results Ready
Once your sample reaches the lab, testing begins. We’ll contact you to book your results consultation.
Some test results may be available within a week, while others (especially complex profiles) may take up to 3 weeks.
  • TSH
  • Free T4 (FT4) and Free T3 (FT3)
  • Reverse T3 (rT3) + FT3:rT3 ratio (conversion insight)
  • Thyroid antibodies: TPOAb, TgAb (Hashimoto’s); TRAb (Graves’)
  • Requisition form
  • 1–2 serum tubes (per lab requirement)
  • Transport pack (ice brick if needed)
  • Prepaid courier/return satchel
  1. Book a blood draw at a pathology collection centre.
  2. Follow lab-specific instructions (often non-fasting; see kit).
  3. The lab processes serum, handling stability as required.
  4. Return via courier/express early in the week.

💡 Important: If you’ve had a recent illness, steroid use, or are on thyroid medication, note this — it influences TSH, T3/T4, and rT3.

How to choose
  • If you’ve only had TSH (± FT4):choose the Extensive panel to add FT3, rT3, and antibodies — the markers most often linked with mood, fatigue, and anxiety despite “normal” results.
  • If autoimmune thyroid disease is suspected:ensure TPOAb/TgAb (± TRAb) are included. Antibodies can be elevated years before overt hormone shifts.
