A Troponin test is often considered the gold standard as a cardiac biomarker. What advantages does it have over other markers?
Why is there an inverse relationship of T4 and TSH in hyper and hypo thyroidism? How do the two correlate?
Part 1
Advantages of Troponin test over other cardiac biomarker
Part 2
T4 is hormone secreted by Thyroid gland.
TSH is hormone is secreted by pituitary gland.
When the level of thyroid hormones (T3 & T4) drops too low, the pituitary gland produces Thyroid Stimulating Hormone (TSH) which stimulates the thyroid gland to produce more hormones. Under the influence of TSH, the thyroid will manufacture and secrete T3 and T4 thereby raising their blood levels.
