What is a thyroid profile?
The thyroid profile consists of a group of tests that can be ordered together for the evaluation of the function of the thyroid gland and as an aid in the diagnosis of thyroid disorders. The tests included in the thyroid profile measure the amount of thyroid hormones in the blood.
The basic thyroid profile generally includes:
- Thyroid stimulating hormone (TSH) is used for the diagnosis of hypothyroidism and hyperthyroidism, and to monitor treatment of thyroid disorders.
- Thyroxine (T4) is used for the diagnosis of hypothyroidism and hyperthyroidism; it may also be used to monitor treatment.
- Triiodothyronine (T3) is used for the diagnosis of hyperthyroidism; it can also be used to monitor treatment.
The complete thyroid profile measures:
- TSH
- Thyroxine (T4)
- Triiodothyronine (T3)
- Reverse T3
- Free T4
- Anti-TG, Anti-TPO, anti-thyroperoxidase antibodies (anti-TPO) and anti-thyroglobulin, which are key to identify any autoimmune alteration in patients, which can lead them to develop diseases that lead to hypothyroidism.
What does the thyroid profile consist of?
By means of a blood sample taken by puncture of a vein in the forearm, the parameters of the thyroid profile are analyzed.
Why is it performed?
When a patient presents symptoms of hypothyroidism or hyperthyroidism due to a condition affecting the thyroid gland, the Endocrinology specialist may indicate that a thyroid profile be performed.
In the case of hypothyroidism some of the signs and symptoms are:
- Weight gain
- Dry skin
- Constipation
- Intolerance to cold
- Thickening or swelling of the skin
- Hair loss
- Fatigue
- Menstrual irregularities in women
Hyperthyroidism includes:
- Increased heart rate
- Anxiety
- Weight loss
- Sleeping difficulties
- Hand tremors
- Weakness
- Diarrhea
- Eye involvement — swelling around the eyes, dryness, irritation, and in some cases, bulging or bulging eyes
Preparation for the thyroid profile
No special preparation is necessary. However, it is important to discuss with your health care provider if you are taking any medications, as they may interfere with the tests included in the thyroid profile.
How do you feel during the test?
As a general rule, the patient will not notice anything during the test, since only a blood sample will be taken to perform the analysis.
Meaning of abnormal results
In the event that the feedback system related to the thyroid gland is not functioning properly, an increase or decrease in the amount of thyroid hormones may occur.
When TSH concentrations are elevated, the thyroid will produce and release inappropriate amounts of T4 and T3, and symptoms associated with hyperthyroidism will occur.
And if the results show a decrease in thyroid hormone production, symptoms characteristic of hypothyroidism will manifest.
