Phlebotomy

Meaning

The clinical procedure involving the puncture of a vein, typically in the arm, to draw a sample of venous blood for laboratory analysis or, less commonly, for therapeutic blood removal to manage conditions like polycythemia vera or hereditary hemochromatosis. This essential practice provides the biological medium necessary for measuring circulating hormone levels, metabolic markers, and overall endocrine function. Accurate phlebotomy technique is critical for obtaining reliable diagnostic data in hormonal health.
