Why Would I Need These Tests
The thyroid gland‘s hormones help control some of your body’s metabolic processes, such as heart rate, blood pressure, body temperature and weight. Too much or too little of these hormones can make you ill.
You might need thyroid tests if:
- you have symptoms of hyperthyroidism or hypothyroidism
- you are taking some form of thyroid hormone replacement treatment
- you are female and being investigated for infertility
Very rarely, babies are born without a working thyroid gland. For this reason, all Australian newborns are screened for hypothyroidism with a TSH test using a drop of blood taken from a heel prick.
How Long Does It Take To Resolve Hyperthyroidism
Drug therapy to normalize thyroid hormone levels can require two to three months. Generally, another year or two of continued drug therapy may be required before there is a true remission of the disorder. Keep in mind that drug therapy does not cure or bring about remission. Remission only occurs when the production of thyroid stimulating antibody has been turned off and that is not effected by drug therapy. Unfortunately, no one can predict when that will happen and it may take years.

Can Pregnancy Cause Me To Develop Thyroid Issues
You may develop an illness called postpartum thyroiditis after you give birth. During the next 12 months, you might experience weight loss, develop an increased sensitivity to heat, and suffer from other health issues. The symptoms of postpartum thyroiditis may resemble the health issues that are associated with hyperthyroidism.
Unfortunately, some healthcare providers may misdiagnose this problem. For example, your healthcare provider might believe that a postpartum mood disorder is causing you to experience these negative symptoms. If you receive a misdiagnosis and do not treat your postpartum thyroiditis, you might develop other health issues. If you are experiencing symptoms of this illness, you should visit our office in Louisville for thyroid testing.
What Day Is Best For Testing
It depends on your goals. For fertility, check estradiol and FSH on day 3 of your menstrual cycle. This is a measure of egg quality and drives progesterone levels. For peak estradiol, check on day 12 of your cycle. I use that for bone mass. For progesterone and to check ovulation, I check day 21-22. If you dont know what day, aim for estradiol and progesterone on day 21-22 as most lab data are standardized for those dates before menopause. If your cycles are very irregular, test day 21-22 after a period.

Thyroid Testing: How It Works
Thyroid tests use a blood sample to measure various hormone levels. Thyroid-stimulating hormone , for example, is often measured to indirectly check if your thyroid gland is producing enough thyroid hormones. TSH levels are usually higher than normal if you have an underactive thyroid .
Thyroid function tests can also measure thyroid hormones like thyroxine to provide a better understanding of how low â or how high â your thyroid hormone levels are.

Preparing For The Tests
You dont need to do anything special to prepare for the thyroid function tests. If a healthcare professional has ordered other blood tests to be taken at the same time, you may need to fast for several hours before the test. They will let you know of any special instructions to follow.
Otherwise, you will not need to follow any specific directions before the test.

Oestradiol is a type of oestrogen and is the main female sex hormone. E2 is essential for egg production, protects you against bone loss, and helps regulate your cholesterol levels. Your E2 levels fall as you age so low levels can be a sign that youre menopausal. If your E2 levels are too high or low it can cause a wide range of symptoms like irregular periods, hot flashes, fatigue, headaches, sleep problems, anxiety, depression, and a low sex drive.
Luteinising hormone plays a key role in reproduction. Mid-cycle, your LH levels increase which triggers your ovaries to release an egg ovulation. If your LH levels are too high or low you might have irregular periods and have trouble getting pregnant. High LH levels can be a sign that youre menopausal or have PCOS.
Follicle-stimulating hormone helps your ovaries to function normally and plays a key role in egg production and ovulation. Your FSH levels naturally increase as you age high levels can be a sign that youâre menopausal. If your FSH levels are too high or low you might have trouble getting pregnant.
Testosterone is a sex hormone thatâs important for your sex drive, bone and muscle health, mood, and cognitive function.

The Role Of The Thyroid
The thyroid is a small, butterfly-shaped gland in the neck. This gland is crucial for producing hormones that control vital functions in the body, such as metabolism. However, if the thyroid produces too much of these hormones, a person may develop a condition called hyperthyroidism. If a person produces too little of these hormones, this may indicate a condition called hypothyroidism. What are the signs of these thyroid diseases?

Signs Of Thyroid Trouble
The American Association of Clinical Endocrinologists estimates that 30 million Americans have some kind of thyroid disorder. That’s a surprising number but even more startling is that up to 50% of people with thyroid disease aren’t even aware that they have it.
“Its common for people to chalk up some thyroid symptoms fatigue, irritability, sleep problems to general life stress,” says Tiffany Hor, MD, an endocrinologist at Rush.
Such nonspecific symptoms are often easy to ignore, but the consequences of postponing diagnosis and treatment can be serious: Over the long term, untreated thyroid issues can lead to health complications ranging from an increased risk of osteoporosis to cardiovascular issues.

His physician should measure thyroid hormone and thyroid stimulating hormone levels to determine if replacement is adequate. Patients also need to be cautioned to take thyroid hormone in the morning one hour before breakfast and make sure not to take iron or calcium-containing products at the same time. This can interfere with thyroid hormone absorption. There are some patients who continue to have hypothyroid symptoms despite seemingly adequate replacement with thyroxine, also known as T4. Thyroxine is a prohormone and must be converted to T3 to become active, especially in the central nervous system. Patients that dont respond to adequate T4 replacement may respond favorable to supplemental T3, which is also known as liothyronine.

Thyroid Testing With Blood
The most common way to test thyroid function, and the test that is considered the gold standard is a blood test, but it is important that you get a complete thyroid test and not just the TSH test.
The complete thyroid test includes:
- TSH This is important because we want to see what messages the brain is sending to the thyroid.
- Free T4 This is the storage form of the thyroid that is made by the thyroid gland in response to TSH, this is also the form of the thyroid that is usually prescribed in medications but some people have a problem converting T4 to T3.
- Free T3 This is the metabolically active form of thyroid hormone which makes it the most important thyroid hormone to be optimal. T4 to T3 conversion happens throughout the body.
- Reverse T3 This is an inactive form of thyroid hormone, important to test because high levels indicate adrenal issues or high levels of inflammation.
- Thyroid antibodies This indicates if you have an autoimmune thyroid problem, also important to test because often this will rise well before there is a problem with the other thyroid hormones.
You can still have normal TSH and even normal T4 levels but have a low thyroid function, check out this video below and I explain the importance of the complete thyroid test, and show a number of different examples of perfect TSH levels but low levels of the metabolically active T3. Note the measurement units in the U.S are different but the principle is still the same.

What Are Early Warning Signs Of Thyroid Problems
Your thyroid is a small gland that produces hormones. Under some circumstances, this gland may begin to produce too many thyroid hormones. This issue is called hyperthyroidism. In contrast, this gland will produce an insufficient amount of hormones if you develop hypothyroidism. There are several early warning signs that may indicate that you have developed one of these thyroid issues.
If you are experiencing these problems, you should schedule a thyroid test at our office in Louisville. After we diagnose your problem, we can recommend medications and other treatments that will relieve your symptoms and enhance your health.
Your Heart Rate Is Changing Or You’re Feeling Heart Palpitations
If you are feeling weird sensations around your chest, neck, or throat, it could be heart palpitations, and they may be caused by your thyroid, not your heart itself. The Mayo Clinic describes a number of things connected with your heart rate that can really indicate hyperthyroidism, including “rapid heartbeat commonly more than 100 beats a minute,” as well as “irregular heartbeat or pounding of your heart .” Dr. Goldfarb explained: “When your thyroid is making too much hormone , you can experience racing heart” as well as “palpitations.” On the other hand, a slower heart rate can indicate hypothyroidism, according to the Mayo Clinic.
Dr. Cohen said that “when thyroid levels are low, we are low” and “our hearts might beat slower.” He added, “If thyroid levels are high, a person will show signs of overactivity,” including a “racing heart.”

What Is The Thyroid Gland
The thyroid gland is a butterfly-shaped endocrine gland that is normally located in the lower front of the neck.

Inside: What Thyroid Tests To Ask For? Various Testing for Thyroid Function and antibodies. Optimal Thyroid Test Result Charts
One of the most common questions that I get asked is that What all tests do I need to get to check my thyroid completely?
Its so unfortunate that most of the patients that I have seen have not gotten the complete thyroid panel.
Majority of the time the only test they get is TSH. Even though these patients have classical symptoms of thyroid dysfunction but nobody has even thought about doing the complete thyroid panel for them.
The reason is that to date the recommendations in the conventional medicine world are to just order TSH to check for thyroid dysfunction.
But often if we just do one test to check for thyroid dysfunction we miss the opportunity to diagnose several other cases who we can help. Unless you have the correct diagnosis how are you going to improve your symptoms?
And even for people who are taking thyroid medicine the only way their medicine is adjusted is based on this test called TSH. And its no surprise that several people who are taking thyroid medicine continue to suffer from symptoms.
It is because often they are under-treated or overrated. Also if we just do one test then we dont know if levothyroxine is the right medicine for you or we need to change your thyroid medicine.
