Introduction
Thyroid tests are essential for diagnosing and managing thyroid disorders, which can affect your energy levels, weight, mood, and overall health. One term you might come across in your thyroid test report is "A/C Status." If you're unsure what this means, don’t worry—this article will explain it in simple terms and help you understand its significance for your health.
What Does A/C Status Mean in Thyroid Tests?
The term "A/C Status" stands for "Antibody/Cell Status." It refers to the presence or absence of thyroid antibodies in your blood, which can indicate an autoimmune thyroid condition.
Common Thyroid Antibodies Tested:
1. Anti-Thyroid Peroxidase Antibodies (TPO Ab): Linked to Hashimoto’s thyroiditis (an autoimmune cause of hypothyroidism).
2. Thyroglobulin Antibodies (Tg Ab): Also associated with Hashimoto’s and sometimes thyroid cancer monitoring.
3. Thyroid-Stimulating Immunoglobulin (TSI): Seen in Graves’ disease (an autoimmune cause of hyperthyroidism).
If your report says "A/C Status: Positive," it means these antibodies were detected, suggesting an autoimmune thyroid disorder. If it says "Negative," no such antibodies were found.
Why Is A/C Status Important?
Thyroid antibodies can attack your thyroid gland, leading to:
Hashimoto’s thyroiditis (underactive thyroid)
Graves’ disease (overactive thyroid)
Knowing your A/C status helps doctors:
Confirm if your thyroid issue is autoimmune.
Predict disease progression (e.g., Hashimoto’s may worsen over time).
Guide treatment (some cases need immune-modulating approaches).
Symptoms of Autoimmune Thyroid Disorders
Here are some symptoms:
Hashimoto’s (Hypothyroidism)
Fatigue, weight gain
Cold intolerance
Dry skin, hair loss
Depression, brain fog
Graves’ Disease (Hyperthyroidism)
Weight loss, rapid heartbeat
Anxiety, tremors
Heat intolerance, sweating
Bulging eyes (in some cases)
If you have these symptoms and a positive A/C status, your doctor may recommend further tests like TSH, Free T3, and Free T4 to assess thyroid function.
What Causes Autoimmune Thyroid Disorders?
The exact cause is unclear, but risk factors include:
Genetics: Family history of thyroid disease.
Gender: Women are more prone.
Stress & Infections: Can trigger autoimmune responses.
Nutrient Deficiencies: Low selenium, vitamin D, or iodine imbalance.
Managing Autoimmune Thyroid Conditions
While autoimmune thyroid disorders are chronic, proper management can help you lead a healthy life.

Medical Treatment
Hypothyroidism (Hashimoto’s): Thyroid hormone replacement (e.g., Levothyroxine).
Hyperthyroidism (Graves’): Anti-thyroid meds, beta-blockers, or radioactive iodine therapy.
Lifestyle & Diet Tips
1. Eat Anti-Inflammatory Foods: Include omega-3s (fish, flaxseeds), antioxidants (berries, leafy greens).
2. Avoid Gluten (If Sensitive): Some studies link gluten to Hashimoto’s flare-ups.
3. Manage Stress: Yoga, meditation, and deep breathing help reduce immune triggers.
4. Check Vitamin Levels: Optimise vitamin D, selenium, and zinc (consult a doctor first).
5. Exercise Moderately: Gentle activities like walking or swimming support metabolism.
When to See a Doctor?
If you experience:
Unexplained weight changes
Extreme fatigue or mood swings
Irregular heartbeat or temperature sensitivity
Get tested! Early diagnosis prevents complications like heart disease or infertility.
