Hashimoto’s Symptom Quiz
This Hashimoto’s symptom quiz gives you a weighted score that combines your symptoms with the autoimmune-specific risk factors (family history, other autoimmune conditions, postpartum status, and antibody results) that actually distinguish Hashimoto’s from generic hypothyroidism. It’s designed for adults asking “do I have Hashimoto’s?” and trying to figure out if antibody testing is the right next step.
Here’s how to use it:
Check every symptom you’ve had for the last 2 months, flag any risk modifiers that apply, and hit calculate. Your total is given out of a possible 56 points and drops you into one of four tiers with a clear next step. It’s that easy.
The scoring system weights symptoms by how specifically they point at autoimmune thyroid disease, not just low thyroid function. Risk modifiers carry significant weight because Hashimoto’s is fundamentally an antibody-and-genetics diagnosis[1][2]. If you’ve already had thyroid antibodies tested and they were elevated, the quiz treats that as diagnostic and adjusts your tier accordingly.
Note: This quiz is a screening tool, not a diagnosis. A confirmed Hashimoto’s diagnosis requires TPO and thyroglobulin antibody testing. Never start, stop, or change thyroid treatment based on this score alone.

How to Use This Quiz
Step #1: Check the Symptoms That Apply to You
The quiz is organized by category: general symptoms, thyroid gland signs, the autoimmune pattern, skin and inflammation, and reproductive symptoms. Go through each section and check every symptom you’ve had for at least 2 months.
Don’t over-check. A symptom that comes and goes occasionally, or that’s clearly tied to something else (a new medication, a stressful month, a recent illness), doesn’t belong.
Skip anything you’re not sure about.
Step #2: Add Your Risk Modifiers
The Risk Modifiers section captures factors that raise your baseline risk of Hashimoto’s independent of symptoms: another autoimmune condition, a family history of thyroid or autoimmune disease, being female and over 35, postpartum within the past 18 months, and known elevated thyroid antibodies.
These matter more for Hashimoto’s than they do for generic hypothyroidism. Hashimoto’s runs in families, clusters with other autoimmune diseases, spikes after pregnancy (postpartum thyroiditis affects 5 to 10 percent of women[3]), and is 7 to 10 times more common in women than men[4]. Ignoring any of these would underestimate your real risk.
The antibody modifier carries the most weight in the quiz. If you’ve had TPO or thyroglobulin antibodies tested and the result was elevated, at the upper end of the reference range, or barely above the cutoff, that’s diagnostic of Hashimoto’s by definition. The quiz floors your tier to Moderate when that box is checked, regardless of how many other items you select.
Step #3: Read Your Score and Follow the Next Step
Click “Calculate My Score” and your total appears out of a possible 56 points (36 symptom points plus 20 modifier points). Your total places you into one of four tiers: Low Likelihood (0 to 9), Mild Pattern (10 to 19), Moderate Pattern (20 to 29), or Strong Pattern (30 and above).
Each tier comes with a specific next step. A Low score means your symptoms are most likely driven by something other than autoimmune thyroid disease. A Mild or Moderate score means antibody testing is the right next step. A Strong score, or any score with the antibody box checked, means you have a high-probability Hashimoto’s pattern and should be working with a clinician on monitoring and management.
Once you have antibody and thyroid lab results, plug the numbers into the Optimal Thyroid Lab Test Calculator to see where they fall against optimal ranges, not just the standard reference range.
Understanding Your Results
Your Score
Your score is the sum of the weighted symptoms and risk modifiers you checked. The maximum possible is 56: 36 symptom points from 22 weighted symptoms, plus 20 modifier points from 6 risk factors.
Symptoms have a weight of 1, 2, or 3 depending on how specifically they point at Hashimoto’s. Classic hypothyroid symptoms (fatigue, cold intolerance, dry skin, hair loss) carry weight 1 because they appear in many causes of low thyroid function, not just Hashimoto’s. Autoimmune-specific items (visible neck swelling, symptoms that come and go in flares, swings between sluggish and wired states) carry weight 2 or 3 because they’re far more predictive of autoimmune thyroiditis specifically.
The antibody modifier alone weighs 8 points, which is why a single positive antibody check can lift your tier even when symptoms are subtle.
Your Symptom Pattern Breakdown
Below your score, the quiz shows the three categories where your strongest symptom pattern sits. The autoimmune pattern category (flares, sluggish/wired swings, food-trigger crashes, post-stress flares) is the most predictive section — heavy scoring there pushes Hashimoto’s toward the top of the differential, even when classic hypothyroid symptoms are mild.
Your modifier total is shown separately so you can see how much of your score comes from your pretest probability versus your active symptoms. A high modifier total with low symptom score is a typical subclinical Hashimoto’s pattern.
Your Risk Tier
The four tiers are calibrated conservatively. A Low score (0 to 9) means symptoms and risk are not strongly suggestive of autoimmune thyroid disease. A Mild score (10 to 19) means there’s some autoimmune signal worth investigating with antibody testing.
A Moderate score (20 to 29) means your pattern is clearly consistent with Hashimoto’s and antibody testing is strongly recommended. A Strong score (30 or higher) means a high-probability Hashimoto’s pattern that warrants comprehensive workup. Anyone who checks the antibody modifier is automatically placed at Moderate or higher, because elevated TPO or thyroglobulin antibodies are diagnostic of Hashimoto’s by definition[1].
Your Recommended Next Step
The next step scales with your tier and antibody status. A Low tier suggests addressing more likely drivers first: iron, vitamin D, sleep quality, stress, and gut health. A Mild tier suggests requesting TPO and thyroglobulin antibodies plus a baseline thyroid panel.
A Moderate or Strong tier without antibody confirmation suggests requesting the full antibody panel along with TSH, Free T3, and Free T4. A Moderate or Strong tier with antibody confirmation already in hand shifts the focus from diagnosis to management: tracking TSH and antibody trajectory every 6 to 12 months, addressing autoimmune triggers (gluten, gut health, selenium, vitamin D, stress), and treating with thyroid hormone if labs trend out of optimal range.
Once you have labs in hand, the Optimal Thyroid Lab Test Calculator will tell you whether your numbers fall within the optimal range. A “normal” TSH alongside positive antibodies is the most common pattern for early-stage Hashimoto’s, and that’s often where the answer lives.
The Stages of Hashimoto’s
Hashimoto’s is rarely an “either you have it or you don’t” diagnosis. It progresses through stages, and most people pass through the first stages for years before symptoms or lab abnormalities are obvious enough for a doctor to act on[1]. Understanding which stage you might be in helps you interpret your quiz score in context.
| Stage | Antibody Status | TSH | Free T4 | Symptoms | Recommended Action |
|---|---|---|---|---|---|
| Subclinical Hashimoto’s | Positive (TPO and/or TgAb) | Normal | Normal | Few or none | Annual TSH and antibody monitoring; address autoimmune triggers |
| Subclinical hypothyroidism with Hashimoto’s | Positive | Mildly elevated (4.5 to 10 mU/L) | Normal | Mild fatigue, brain fog, weight changes | Treatment depends on age, symptom load, pregnancy plans, and antibody titers |
| Overt hypothyroidism from Hashimoto’s | Positive | Above 10 mU/L | Below reference range | Classic hypothyroid symptoms across multiple body systems | Levothyroxine treatment with TSH recheck every 6 to 8 weeks |
| Hashitoxicosis (transient) | Positive | Suppressed | Elevated | Anxiety, racing heart, weight loss, heat intolerance | Symptom management; monitor closely for transition to hypothyroid phase |
The earliest stages are where most patients get dismissed. A “normal” TSH with positive antibodies and mild symptoms gets a “your labs are fine” response from many providers, even though the autoimmune process is already established. That’s exactly the gap this quiz is designed to catch.
Frequently Asked Questions
The early signs of Hashimoto’s are usually subtle and easy to miss because they overlap with everyday tiredness, stress, or perimenopause. The most common early signs are persistent fatigue, gradual weight gain, brain fog, dry skin, hair loss, and unexplained mood changes[1]. None of these are specific to Hashimoto’s by themselves.
The earlier autoimmune-specific signs are the ones most patients (and many doctors) miss. Symptoms that come and go in flares rather than being constant, energy crashes after eating gluten, visible swelling in the front of the neck, and a feeling of pressure or “lump in throat” when swallowing all point much more specifically at Hashimoto’s than fatigue alone does. When those signs cluster with risk factors like another autoimmune condition or a family history of thyroid disease, it’s worth requesting TPO and thyroglobulin antibodies, even if your TSH is in the normal range.
Hashimoto’s is the autoimmune disease that causes most cases of hypothyroidism in countries with adequate iodine intake. Said simply: Hashimoto’s is the underlying disease, and hypothyroidism is the functional result[1].
A patient with Hashimoto’s eventually develops hypothyroidism as the immune system gradually destroys thyroid tissue, but antibodies can be elevated for years before thyroid function actually drops.
The practical difference is diagnostic. Diagnosing Hashimoto’s requires antibody testing (TPO antibodies, thyroglobulin antibodies, or both). Diagnosing hypothyroidism requires only TSH and Free T4. Treatment overlaps because both are managed with thyroid hormone replacement when treatment is needed, but a Hashimoto’s diagnosis opens up additional autoimmune-management strategies (gluten avoidance, selenium, gut health, identifying other autoimmune triggers). For a deeper look at the symptom picture of low thyroid function, take the Hypothyroid Symptom Quiz.
Hashimoto’s is diagnosed by blood test, specifically a positive thyroid peroxidase (TPO) antibody, a positive thyroglobulin (TgAb) antibody, or both[1]. Symptoms alone cannot diagnose Hashimoto’s because they overlap with hypothyroidism from other causes and with many non-thyroid conditions.
The standard antibody panel is TPO antibodies, with thyroglobulin antibodies added for patients with negative TPO and a strong clinical suspicion. Imaging (thyroid ultrasound) can support the diagnosis when antibodies are negative but the gland looks structurally heterogeneous, which is the appearance of an immune-attacked thyroid.
Many providers order only TSH and call it a day. That’s the single most common reason patients with Hashimoto’s go undiagnosed for years. If your symptoms suggest Hashimoto’s and your provider hasn’t ordered antibodies, ask for them specifically.
Yes. You can have Hashimoto’s with a completely normal TSH. This is one of the most common diagnostic gaps in thyroid medicine.
Hashimoto’s is an antibody-driven disease. The immune system starts attacking the thyroid years before that attack damages enough tissue to push TSH out of the normal range[1]. During that window, antibodies are positive, the patient is often symptomatic, and TSH still reads “normal.” This is called subclinical Hashimoto’s, and it’s frequently dismissed by providers focused only on TSH.
The pattern to watch for: classic hypothyroid-style symptoms (fatigue, brain fog, hair loss, mood changes, cold intolerance) plus autoimmune-specific signs (symptom flares, gluten reactions, family history) with a TSH between 1.5 and 4.5 mU/L. That combination warrants TPO and thyroglobulin antibody testing regardless of where TSH lands. For more on this, read my guide on optimal TSH levels for thyroid patients.
TPO (thyroid peroxidase) antibodies and thyroglobulin (TgAb) antibodies are blood markers that indicate your immune system is attacking your thyroid gland. They are the diagnostic markers for Hashimoto’s thyroiditis[1].
TPO antibodies are the more common of the two. About 90 to 95 percent of Hashimoto’s patients have positive TPO antibodies. Thyroglobulin antibodies are positive in about 60 to 80 percent of cases and can be the only positive marker in a smaller subset of patients, which is why both are typically tested together when Hashimoto’s is suspected.
The single most important detail about antibody results: any positive value is meaningful, not just dramatically elevated ones. A TPO of 35 with a reference range under 30 is positive Hashimoto’s. So is a TPO of 350. The titer (the number) doesn’t have to be high to make the diagnosis. Don’t accept “your antibodies are barely elevated, that’s not concerning” as a final answer if you’re symptomatic.
Yes. Hashimoto’s has a strong hereditary component. Having a parent, sibling, or child with Hashimoto’s or any other autoimmune thyroid disease meaningfully raises your own risk[2].
Genetic susceptibility doesn’t operate in isolation. Hashimoto’s runs in families and clusters with other autoimmune diseases — celiac, type 1 diabetes, vitiligo, lupus, rheumatoid arthritis, Sjögren’s, and others. A patient with celiac and a sister with rheumatoid arthritis is at much higher risk for Hashimoto’s than someone with no autoimmune family history at all, which is why the quiz weights both family thyroid history and family non-thyroid autoimmune history as separate modifiers.
Genes load the gun, but environmental triggers (stress, infection, pregnancy, gluten in susceptible patients) usually pull the trigger. Most patients can identify a specific period when their symptoms started, and a family history is what tells you which direction the trigger pointed.
Yes. Pregnancy and the postpartum period are well-recognized triggers for Hashimoto’s onset and for sudden Hashimoto’s flares in women who already had subclinical disease.
Postpartum thyroiditis affects 5 to 10 percent of women in the 12 months after childbirth, and a significant portion of those cases are early Hashimoto’s revealing itself for the first time[3]. The pattern often begins as a transient hyperthyroid phase (anxiety, racing heart, weight loss, insomnia) followed by a hypothyroid phase (fatigue, weight gain, depression, cold intolerance). Either phase can resolve fully, but a meaningful percentage of women progress to chronic Hashimoto’s.
If you’ve given birth in the past 12 to 18 months and your symptoms started or worsened during that window, it’s worth requesting TPO and thyroglobulin antibodies along with TSH. Postpartum thyroid dysfunction is often dismissed as “new mom fatigue” or postpartum depression, when it’s actually treatable thyroid disease.
Yes. Hashimoto’s can affect fertility, menstrual cycles, and pregnancy outcomes — even when TSH is technically within the normal range.
Heavy or irregular periods are one of the most common menstrual changes, driven by the disruption that low or fluctuating thyroid hormone causes to the menstrual cycle. Anovulatory cycles (cycles where no egg is released) are also more common, which directly affects fertility.
The fertility piece goes beyond ovulation. Elevated TPO antibodies are independently associated with increased risk of unexplained infertility and miscarriage, regardless of TSH[5]. That association is one of the strongest reasons for women trying to conceive (or with a history of unexplained pregnancy loss) to request a full thyroid panel including antibodies, not just TSH.
