My TSH was "normal" for 3 years. arq. found Anti-TPO at 380 — Hashimoto's. Finally had an answer.
Your endocrinologist reads TSH, free T3, free T4, anti-TPO, and anti-Tg together — the full autoimmune-aware panel. Subclinical hypothyroidism is titrated, not ignored. Levothyroxine is dosed on bloodwork, not on a GP hunch.
Every panel includes a 15–20 minute video consult with a specialist — read against South Asian-calibrated ranges. The AI works invisibly. The doctor does the medicine.
Your thyroid controls metabolism, energy, weight, mood, and hair. Standard tests check only TSH — but TSH alone misses 40% of thyroid dysfunction. You need TSH + Free T3 + Free T4 + TPO antibodies + reverse T3 to see the full picture. "Normal" TSH (0.5–4.5) is not optimal — functional range is 1.0–2.0 mIU/L.
Approximately 1 in 10 Indians has thyroid dysfunction. Most are diagnosed late—or not at all—because thyroid screening relies on a single marker: TSH. By then, autoimmune damage has progressed for years. Women are affected 8x more often than men, yet most don't learn they're sick until symptoms become severe. Thyroid dysfunction often coexists with PCOS, weight gain, and fatigue.
These biomarkers reveal the root causes — and what actually works to fix them.
Most Indian GPs test TSH only. arq. tests the complete panel to reveal autoimmune disease, conversion issues, and early dysfunction.
| Marker | What It Measures | Standard Test? | arq. Panel? | Why It Matters |
|---|---|---|---|---|
| TSH | Pituitary signal for thyroid | ✓ | ✓ | Standard marker—but only part of picture. Normal TSH masks conversion and autoimmune issues. |
| Free T3 | Active hormone your cells use | ✗ | ✓ | Reveals conversion problems: normal total T3 but cells can't access it. Explains fatigue despite "normal" TSH. |
| Free T4 | Raw thyroid output from gland | ✗ | ✓ | Drops before TSH rises, so it catches early hypothyroidism GPs miss. Essential to optimize Levothyroxine dosing. |
| Anti-TPO | Antibodies attacking thyroid | ✗ | ✓ | Marks Hashimoto's autoimmune disease. Present years before TSH rises. Early detection enables preventive care. |
| Anti-Thyroglobulin | Second autoimmune marker | ✗ | ✓ | Confirms autoimmune thyroiditis. Often elevated with Anti-TPO. Guides long-term treatment strategy. |
| Reverse T3 | Stress-driven thyroid dysfunction | ✗ | ✓ | High levels mean hormone is shunted into inactive form. Reflects burnout, poor sleep, malnutrition. Almost never tested in India. |
"Normal" TSH varies widely. Here's what each range actually means for your health and what action to take.
| TSH Range | Classification | Common Symptoms | Action Required |
|---|---|---|---|
| 1.0 – 2.0 | Optimal | None—most symptom-free range. Energy stable, metabolism healthy. | Maintain current protocol. Monitor annually. |
| 0.5 – 4.5 | Normal Lab Range | Variable. Low end (0.5–1.0) or high end (3.5–4.5) often causes symptoms despite "normal" label. | Check Free T3, Free T4, and antibodies. Don't assume you're fine. |
| 4.5 – 10 | Subclinical Hypothyroid | Fatigue, weight gain, cold intolerance, brain fog. Often told "your numbers are fine." | Test antibodies and optimize lifestyle first. Consider low-dose Levothyroxine if symptoms persist. |
| > 10 | Overt Hypothyroid | Severe fatigue, significant weight gain, cold intolerance, depression, slowed metabolism. | Start Levothyroxine immediately. Adjust dosing monthly until TSH reaches 1.0–2.0 and symptoms improve. |
| < 0.5 | Subclinical Hyperthyroid | Anxiety, palpitations, tremor, night sweats, heat intolerance, restlessness. | Reduce Levothyroxine dose. May indicate overtreatment or early Graves' disease. Check Free T3, Free T4. |
Three steps. Your data. Your physician. Your protocol.
100+ biomarkers drawn at your door in 10 minutes. NABL-accredited labs. Results in 5 days. No clinic visit, no waiting rooms — just data.
Your physician reviews all 8 thyroid markers and explains the root cause — autoimmune, conversion failure, or gland dysfunction. Every number in context.
Medication dosing optimised for your Free T4 and symptoms. Anti-inflammatory and nutritional support for autoimmunity. Delivered in 48h. Adjusted monthly until optimal.
TSH alone misses 40% of thyroid dysfunction, including subclinical disease, autoimmune markers, and conversion problems. A full panel (TSH + Free T3 + Free T4 + TPO + Anti-Tg + Reverse T3) reveals root causes GPs overlook.
Most thyroid patients feel symptom-free only in the 1.0–2.0 range. If your TSH is 3.5–4.5, you may experience fatigue, weight gain, and brain fog despite being told "everything is normal."
Anti-TPO and Anti-Thyroglobulin antibodies are present 5–10 years before TSH rises. Early detection enables preventive nutrition and lifestyle interventions to slow autoimmune progression and preserve thyroid function.
Many hypothyroid patients on Levothyroxine have "normal" TSH but low Free T3 or Free T4—meaning their dose is inadequate or their body isn't converting thyroid hormone efficiently. This explains persistent fatigue despite treatment.
High Reverse T3 indicates your body is shunting thyroid hormone into an inactive form due to stress, poor sleep, or malnutrition. This is almost never tested in standard Indian clinics but explains why some patients don't respond to medication alone.
No AI chat. No templates. No copy-paste PDFs. A specialist reads your panel against South Asian-calibrated ranges and writes the protocol on a 15–20 minute video consult — inside 7 days of your home draw.
