The Thyroid Health Test Kit is a convenient at-home blood test designed to evaluate key thyroid hormones that regulate metabolism, energy, mood, and overall endocrine function. By measuring TSH, Free T3, and Free T4, this test provides a clear picture of how well your thyroid is functioning and helps identify potential imbalances such as hypothyroidism or hyperthyroidism.
Thyroid dysfunction often develops gradually and may go unnoticed until symptoms significantly impact your daily life. Routine testing allows for early detection, proactive management, and better long-term health outcomes.
Why Monitor Thyroid Health?
Your thyroid gland plays a central role in regulating nearly every system in your body—including metabolism, heart rate, body temperature, and brain function.
When thyroid hormone levels are out of balance, it can affect:
- Energy levels and fatigue
- Weight management
- Mood and cognitive function
- Hormonal balance and metabolism
Because symptoms can be subtle or mistaken for other conditions, testing is one of the most reliable ways to identify thyroid issues early and guide appropriate next steps.
Thyroid Stimulating Hormone (TSH)
What it measures:
TSH is produced by the pituitary gland and signals your thyroid to produce hormones. It is the primary screening marker for thyroid function.
Why it matters:
TSH helps determine whether your thyroid is underactive or overactive. High or low levels often indicate underlying dysfunction.
If levels are high (possible hypothyroidism):
- Fatigue
- Weight gain
- Cold sensitivity
- Depression or brain fog
If levels are low (possible hyperthyroidism):
- Anxiety or irritability
- Rapid heart rate
- Weight loss
- Heat intolerance
Free T4 (Thyroxine)
What it measures:
Free T4 is the primary hormone produced by the thyroid and circulates in the bloodstream before being converted into active T3.
Why it matters:
It reflects how much hormone your thyroid is producing and available for conversion.
If levels are low:
- Fatigue
- Weight gain
- Dry skin
- Hair thinning
If levels are high:
- Increased sweating
- Nervousness
- Insomnia
- Unintentional weight loss
Free T3 (Triiodothyronine)
What it measures:
Free T3 is the active form of thyroid hormone responsible for regulating metabolism, heart rate, and energy production.
Why it matters:
It shows how effectively your body is converting T4 into usable energy.
If levels are low:
- Low energy and sluggishness
- Difficulty concentrating
- Weight gain
If levels are high:
- Rapid heartbeat
- Anxiety
- Increased appetite
- Trouble sleeping

What this Test measures
Thyroid Test Panel
The thyroid gland is a butterfly-shaped endocrine gland located in the lower front of the neck. The thyroid’s job is to make thyroid hormones, which are secreted into the blood and then carried to every tissue in the body. Thyroid hormones help the body use energy, stay warm, and keep the brain, heart, muscles, and other organs working as they should. My Labs Direct’s thyroid test is one of the best ways to learn more about the current health of your thyroid gland and ensure its functioning properly.
Thyroid stimulating hormone is made by the thyroid gland and is released into the blood where it is delivered to tissues in the body. It helps the body stay warm, use energy, and keeps the brain, heart, muscles, and other organs working as they should. TSH can serve as an ‘early warning system’ in the body because it will indicate early changes in thyroid function before thyroid hormones become too high or too low. Because of this, measuring the TSH level in a blood sample is considered the best way to initially test thyroid function.
High TSH levels: The pituitary gland produces more TSH when the thyroid gland does not produce enough hormones. High levels are an indication that the thyroid gland is not making enough thyroid hormone (primary hypothyroidism).
Low TSH levels: Low TSH levels are an indication that the thyroid is producing too much thyroid hormone (hyperthyroidism or overactive thyroid). Low TSH may result from an abnormality in the pituitary gland. This abnormality prevents it from making enough TSH to stimulate the thyroid.
Symptoms of high TSH levels:
- Rapid heartbeat
- Muscle weakness
- Nervousness or irritability
- Insomnia
- Frequent bowel movements or diarrhea
- Weight loss
- Mood changes
Symptoms of low TSH Levels:
- Weight gain
- Fatigue
- Swelling of face
- Sensitivity to cold temperatures
- Slow heart rate
- Dry skin
- Depression
- Constipation
The thyroid produces a hormone called triiodothyronine, known as T3. Most of the T3 in your body binds to protein. The T3 that doesn’t bind to protein is called Free T3. It helps regulate the speed with which the cells/metabolism work. It also regulates your heart rate and how fast your intestines process food. Measuring T3 in the blood is a way to determine if there is a thyroid problem.
High levels of Free T3 levels cause an excessively high metabolic rate and increased risk of hyperthyroidism.
Low levels of Free T3 levels cause slowed metabolic rate and may be a sign of hypothyroidism.
Symptoms of high levels of Free T3 levels:
- Rapid heart rate
- Elevated blood pressure
- Anxiety
- Increased sweating
- Insomnia
- Weight loss
Symptoms of low levels of Free T3 levels:
- Fatigue
- Weight gain
- Puffy face
- Trouble tolerating cold
- Constipation
- Dry skin
- Thinning hair
- Depression
- Slowed heart rate
T4, also called thyroxine, is the main form of thyroid hormone made by the thyroid gland. T4 is mostly bound to proteins with a small amount unbound, or free. This test measures the amount of free/or unbound T4 circulating through the blood and indicates how well the thyroid gland is functioning.
High levels of Free T4 may be caused by certain thyroid problems such as thyroiditis, a goiter, high levels of protein in the blood, and hyperthyroidism.
Low levels of Free T4 may be caused by fasting, malnutrition, iodine deficiency, medication that affects protein levels, illness, pituitary problems, and hypothyroidism.
Symptoms of high Free T4:
- Anxiety
- Unplanned weight loss
- Tremors
- Diarrhea
Symptoms of low Free T4:
- Weight gain
- Fatigue
- Hair loss
- Low tolerance for cold temperatures
- Irregular period
- Constipation

Does your thyroid function impact weight gain?
The thyroid is a small, butterfly shaped endocrine gland located in your neck that produces three hormones: Thyroxine (T4), Triiodothyronine (T3) and Calcitonin. These hormones are secreted into the blood, and two of them, T3 and T4, directly impact your metabolism. How? These hormones regulate how quickly your body’s cells work. If your thyroid secretes too much T4 and T3, your cells will become charged and start working faster than normal – this is called Hyperthyroidism, or overactive thyroid. If your thyroid secretes too little of the hormones, your cells will slow. This condition is called Hypothyroidism, or underactive thyroid.
So how does this over or under production of T4/T3 impact your metabolism? T3 and T4 control your heart rate, body temperature and, as it relates to metabolism, they also regulate how quickly your intestines process foods and how fast calories are burned. The condition of under-production of T3 and T4, commonly referred to as Hypothyroidism, can make it impossible to lose weight if not treated. While scientists don’t fully understand why an underactive thyroid causes weight gain or prevents weight loss, they suspect it’s due to:
- Slow metabolism
- Lack of energy that leads to less activity
- Changes in how your body processes, stores and burns off fat and glucose
- Fluid retention
What is Hypothyroidism?
Hypothyroidism occurs when the thyroid stops producing enough T3 and/or T4 and metabolic function becomes impaired. The most common causes of hypothyroidism are autoimmune failure (Hashimoto’s Thyroiditis) and surgical removal or destruction of the thyroid gland which occurs when a goiter is removed or to treat thyroid cancer.
Signs and symptoms of hypothyroidism (underactive thyroid) include:
- Fatigue
- Sleepiness
- Mood swings
- Forgetfulness
- Weight gain
- Depression/irritability
- Muscle cramping and aching
- Weakness
- Decreased perspiration
- Changes in blood pressure
- High cholesterol
- Swelling in legs
- Blurred vision
- Cold intolerance
- Hoarse voice
- Heavy menses
- Coarse, dry hair and skin
- Hair loss (on head and/or body)
- Constipation
What will my results tell me?
MLD’s Thyroid At Home test results will provide detailed information regarding your TSH, T3 and T4 levels. Our easy to navigate patient dashboard will tell you if your thyroid levels are low, normal or high.
Interpreting thyroid blood test results:
Comparing TSH with T4 values can provide you and your healthcare provider with a picture of a possible thyroid issue. For example:
- Normal TSH + normal T4 = normal thyroid function
- Low TSH + high T4 = hyperthyroidism/overactive thyroid
- High TSH + low T4 = hypothyroidism/underactive thyroid
- Low TSH + low T4 = low thyroid function due to another problem, such as pituitary gland dysfunction
Can I share my results with my healthcare provider?
Your results can be easily shared with your healthcare provider, and in fact, we encourage you to share your data in order to obtain the treatment you might need. Contact us for a network of healthcare providers that specialize in treating hormone deficiencies.
