Which blood tests are frequently used to identify the causes of cycle deviations?
Answer
TSH, prolactin, and androgens
When investigating persistent menstrual irregularities, healthcare providers often order blood tests to check levels of TSH (thyroid-stimulating hormone), prolactin, and androgens. These specific hormones are key regulators of the delicate balance required for a predictable cycle. Imbalances in thyroid function, prolactin levels, or androgen levels are common culprits for cycle disruptions and can often be identified and addressed through diagnostic blood work.
