AI Thyroid Panel (TSH, T3, T4) Analysis

Thyroid Panel analysis — free ai thyroid test analyser

DrKumar.ai EditorialUpdated March 20264 min readReviewed by DrKumar medical team

Thyroid problems are the most common hormone issue worldwide, especially in women, and most lab reports give you a single TSH number with a generic range. The full pattern — TSH alongside free T3, free T4, and antibodies — tells a much richer story. DrKumar.ai reads the whole panel and tells you whether you're looking at hypothyroidism, hyperthyroidism, subclinical drift, or a stable healthy thyroid.

What a thyroid panel measures

A thyroid panel typically includes TSH (thyroid-stimulating hormone, made by the pituitary), free T4 (the inactive thyroid hormone), free T3 (the active one), and sometimes anti-TPO and anti-thyroglobulin antibodies for autoimmune patterns.

TSH alone can be misleading. A "normal" TSH between 0.4 and 4.0 mIU/L looks fine — but TSH of 3.8 with low free T4 is a different story from TSH of 0.6 with normal free T4. The full panel disambiguates patterns that a single value can't.

Autoimmune patterns (Hashimoto's, Graves') are common, often under-diagnosed, and require the antibody tests to surface. If you have a family history of thyroid issues or symptoms that don't match a "normal" TSH, the antibody panel is what catches it.

Who needs this test

  • Women over 30 — thyroid issues are 5–8x more common in women

  • Anyone with unexplained fatigue, weight change, cold/heat intolerance, hair thinning, or mood changes

  • Anyone with a family history of Hashimoto's, Graves', or hypothyroidism

  • Anyone on levothyroxine — to confirm the dose is correct (target TSH 0.5–2.5 for most patients on treatment)

  • Anyone pregnant or planning pregnancy — thyroid dysfunction affects fertility and pregnancy outcomes

How DrKumar.ai reads your thyroid panel

Upload your thyroid panel — DrKumar.ai handles partial panels (just TSH), standard ones (TSH + T4), and full panels (TSH + free T3 + free T4 + antibodies). Every value is matched to age- and pregnancy-status-specific reference ranges where they differ.

The narrative output names the pattern: euthyroid (healthy), subclinical hypothyroid (high TSH, normal T4), overt hypothyroid (high TSH, low T4), subclinical hyperthyroid (low TSH, normal T4), overt hyperthyroid (low TSH, high T4), Hashimoto's pattern (positive antibodies), or treatment-target pattern (for patients on levothyroxine).

If you've uploaded prior reports, the trend view is especially valuable for thyroid — TSH drifts slowly, and a stable TSH across three tests over a year tells you more than any single value.

TSH (THYROID-STIMULATING HORMONE) · mIU/L
Every thyroid panel you upload is plotted against the normal-range band so you see whether you're drifting, responding, or stable.

Sample analysis output

What the AI returns for typical values

MarkerValueVerdictDrKumar interpretation
TSH5.8 mIU/L Above rangeAbove 4.0 mIU/L upper limit. Subclinical hypothyroidism likely if free T4 is still in range; overt if T4 is below range.
Free T40.9 ng/dL Below rangeBelow the 1.0 ng/dL floor. Combined with elevated TSH, this is the overt hypothyroidism pattern.
Free T32.8 pg/mL NormalWithin range. Doesn't change the headline interpretation when T4 and TSH are abnormal.
Anti-TPO Ab240 IU/mL Above rangeAbove 35 IU/mL. Positive anti-TPO antibodies indicate Hashimoto's thyroiditis — the most common cause of hypothyroidism.

Reader questions

What's the difference between hypothyroidism and Hashimoto's?
Hypothyroidism is the state of an underactive thyroid (low thyroid hormone production). Hashimoto's is one specific cause of hypothyroidism — an autoimmune attack on the thyroid gland. Most hypothyroidism in developed countries is Hashimoto's. Diagnosing the cause matters because Hashimoto's is associated with other autoimmune conditions and progresses over time.
Is a TSH of 3.5 normal?
Technically yes — the standard reference range is 0.4–4.0 mIU/L. But many endocrinologists now treat the optimal range as 0.5–2.5 mIU/L, especially for patients with symptoms (fatigue, weight gain, brain fog) or those trying to conceive. If your TSH is 3.5 and you have symptoms, the full panel including free T4 and antibodies is worth requesting.
Do I need to fast for a thyroid test?
Not strictly required, but if you're being monitored on levothyroxine, take the blood draw before your morning dose — taking the medication first can inflate the T4 reading. Morning draws are generally preferred because TSH has a circadian rhythm.
Can DrKumar.ai analyse thyroid antibody results too?
Yes. If your panel includes anti-TPO (thyroid peroxidase) or anti-thyroglobulin antibodies, the AI reads them and surfaces the Hashimoto's pattern when present. Antibody titres also help predict whether subclinical hypothyroidism is likely to progress.
