Phlebotomy
Phlebotomy is the process of drawing blood from a patient for diagnostic or therapeutic purposes. It is commonly performed by healthcare professionals such as phlebotomists, nurses, or doctors. The blood sample is collected using a needle and syringe or other blood collection device and is then sent to a laboratory for analysis.
Phlebotomy is an important diagnostic tool in healthcare as it allows healthcare professionals to obtain important information about a patient's health status, such as blood glucose levels, cholesterol levels, or the presence of certain infections. It is also used for therapeutic purposes, such as removing excess iron from the blood in patients with hemochromatosis or for blood donation purposes.
Phlebotomy requires knowledge of proper techniques for blood collection, including site selection, patient preparation, and infection control measures. Proper training and certification are necessary for individuals who perform phlebotomy to ensure the safety of patients and healthcare workers.
