Prolactin Test: Purpose, Procedure & Understanding Abnormal Levels

Image
Summary The Prolactin Test (PRL test) measures the level of prolactin , a hormone produced by the pituitary gland , located at the base of the brain. Prolactin plays a vital role in breast development during pregnancy and milk production after childbirth. Normally, prolactin levels remain low in men and non-pregnant women. However, abnormally high levels — a condition known as hyperprolactinemia — may indicate pituitary gland disorders , hormonal imbalances , or certain medic al conditions such as hypothyroidism or kidney disease . This test helps identify underlying causes of infertility , menstrual irregularities , low libido , or galactorrhea (milk secretion in non-lactating individuals) . What Is a Prolactin Test? A prolactin blood test evaluates the amount of prolactin hormone circulating in your bloodstream. Produced by: Pituitary gland (the body’s “master gland”) Main function: Stimulates breast tissue growth and milk production in new mothers ...

What Is Anti-TPO? Causes, Symptoms & High Levels Explained

Image
  Introduction Anti-TPO (Anti-Thyroid Peroxidase Antibodies) are important markers in the diagnosis of autoimmune thyroid diseases. These antibodies are produced when the immune system mistakenly targets thyroid peroxidase, an enzyme crucial for thyroid hormone production. Elevated Anti-TPO levels are commonly associated with Hashimoto’s thyroiditis and Graves’ disease , both of which impact thyroid function. Testing for Anti-TPO antibodies, along with TSH, Free T4, and Free T3 levels , helps in confirming thyroid disorders, predicting disease progression, and guiding treatment plans. 🔬 What Is Anti-TPO? Thyroid peroxidase (TPO) is an enzyme that helps produce thyroid hormones. When the immune system mistakes this enzyme as harmful, it produces Anti-TPO antibodies. Over time, these antibodies can damage thyroid tissue, leading to inflammation, hormone imbalance, and in some cases, hypothyroidism (underactive thyroid). 📈 Causes of Elevated Anti-TPO Seve...
