INTENDED USE: Beckman Coulter A13430 Access Free T3 Calibrator
The Access Free-T3 / triiodothyronine Calibrators are intended to calibrate the Access Free-T3 assay for the quantitative determination of free triiodothyronine levels in human serum and plasma using the Access Immunoassay Systems.
SUMMARY AND EXPLANATION: Beckman Coulter A13430 Access Free T3 Calibrator
Quantitative assay calibration is the process by which samples with known analyte concentrations (i.e., assay calibrators) are tested like patient samples to measure the response. The mathematical relationship between the measured responses and the known analyte concentrations establishes the calibration curve. This mathematical relationship, or calibration curve, is used to convert RLU (Relative Light Unit) measurements of patient samples to specific quantitative analyte concentrations.
Beckman Coulter A13430 Access Free T3 Calibrator: What is a triiodothyronine free T3 test?
A triiodothyronine free T3 test / free triiodothyronine measures the level of T3 in a sample of your blood. It’s used to help diagnose thyroid disease.
Your thyroid is a small, butterfly-shaped gland at the base of your throat. It makes two hormones, T3 and T4 (thyroxine). Hormones are chemical messengers in your bloodstream that control the actions of certain cells or organs.
Thyroid hormones work together to control the way your body uses energy. They affect your weight, heart, body temperature, muscle strength, and even your mood. In children, thyroid hormones affect growth, too.
There are two forms of T3 in your blood:
- Free T3 is the active form that enters your tissues where it’s needed.
- Bound T3 is attached to certain proteins which prevent it from entering your tissues. Most of your T3 is bound.
There are different tests for measuring T3:
- A total T3 test measures both bound and free T3 together. Medical experts think that this test is the more accurate way to measure T3.
- A free T3 test / free triiodothyronine only measures free -T3.
Other names: thyroid function test; total triiodothyronine, free triiodothyronine, FT3, TT3, radioimmunoassay FT3
Beckman Coulter A13430 Access Free T3 Calibrator: What is it free T3 test / free triiodothyronine used for?
A T3 test is used to help:
- Diagnose hyperthyroidism, a condition in which your thyroid gland makes too much thyroid hormone. The test can also help find out what’s causing the condition.
- Diagnose pituitary disorders. The pituitary is a pea-sized gland at the base of your brain. It makes a hormone called TSH (thyroid stimulating hormone). TSH tells the thyroid how much T3 and T4 to make. So, abnormal T3 levels may be a sign of a pituitary problem.
- Monitor treatment for thyroid disease, including hyperthyroidism and hypothyroidism, which is when the thyroid gland makes to little thyroid hormone.
T3 tests are usually ordered with blood tests that measure T4 and TSH (thyroid stimulating hormone) tests.
T3 test Level
- Normal T3 levels (free or total) alone do not rule out thyroid disease. But if your TSH and free T4 levels are also normal, you probably don’t have a thyroid condition.
- High T3 levels (free or total) may mean you have hyperthyroidism (too much thyroid hormone).High T3 levels with:
- Low TSH and high free T4 levels may mean that a problem with your thyroid gland is causing too much thyroid hormone.
- Normal or high TSH and high free T4 levels may mean that a pituitary gland condition is causing too much thyroid hormone.
- Low T3 levels (free or total) may mean hypothyroidism (too little thyroid hormone).Low or normal T3 levels with:
- High TSH levels and low free T4 levels may mean that a problem with your thyroid gland is causing too little thyroid hormone.
- Low TSH and low free T4 levels may mean that a pituitary gland condition is causing too little thyroid hormone.
