• Phlebotomy is the process of collecting blood.
• For thousands of years, medical practitioners clung to the belief that sickness was merely the result of a little “bad blood.”
• To restore bodily harmony, their doctor would simply cut open a vein and drain the blood.
• Roman gladiators would bleed from battle and receive a treatment of further bleeding.
• The unfortunate result of the practice became one reason why it did not last very long.
• In the 12th century, blood letting was practiced by barbers who performed blood letting, surgery, extracting teeth and herb administration.
• Areas of nursing care include coronary heart unit, emergency department, geriatric, ICU, neonatal, nephropathy, obstetrics, oncology, orthopedic, pediatrics, and recovery.
• Hybrid phlebotomy is a blend of centralized and decentralized
• Laboratory sections include administrative office, phlebotomy, urinalysis, hematology, coagulation, clinical chemistry, microbiology, immunology, blood banking, cytogenetics, and molecular diagnosis.
• George Washington, the first president of the US, had a severe throat infection in December 1799.
• The cure that was used as an intervention was massive bleeding.
• George Washington bled more than 9 pints (5 liters) of blood in less than 24 hours and died on December 14.
• After George Washington's death, the philosophy of bleeding as a cure to diseases changed.
• In the mid 19th century, blood letting was no longer considered a cure of illness.
• Anton van Leeuwenhoek discovered microorganisms as the causative agent for many diseases, starting to change the way they treat diseases.
• More modern method was to use leeches (Leeching) - therapeutic phlebotomy.
• Examination involves sample testing and maintaining testing equipment and reagents.
• A Medical Laboratory Technician, under the supervision of a Med Lab Sci, performs general tests.
• The Out Patient Department is for patients who are not admitted in the hospital.
• A Medical Laboratory Scientist performs a wide range of lab tests and confirms and reports lab results.
• A Phlebotomy Technician collects blood samples.
• The phases of sample processing include pre-examination, examination, and post-examination.
• Pre-examination involves request forms, patient identification and information, correct sample collection, correct use of all equipment, sample preparation and centrifugation, and maintaining sample integrity until processing.
• Histopathology examines tissues and cell smears for evidence of cancer, infection or other abnormalities.
• A Histotechnologist prepares body tissue samples for microscopic evaluation of a pathologist.
• Storage of sample after processing is a part of the post-examination phase.
• Post-examination involves reporting of results, ensuring accuracy and reliability of delivery of result, and follow-up if repeat testing is needed or attend to other needs of the physician.
• STAT requests are for emergency cases.
• MRSA infections, HIV testing
• Venesection (Lacing) is a method of phlebotomy where a needle is inserted into a vein and blood is allowed to flow into a collection bag.
• A Pathologist reads and interprets results and examines tissues under the microscope.
• Cupping is a method of phlebotomy where a cup is placed over a vein and the vein is compressed, causing the blood to collect in the cup.
• The phlebotomist's primary role is to collect blood for accurate and reliable test results as quickly as possible with the least discomfort to the patient.
• Centralized phlebotomy is when the phlebotomist is part of the laboratory team and is dispatched to hospital units to collect blood samples.
• Decentralized phlebotomy is when the duties of the hospital staff revolve more than around the patient.
• ancillary hospital areas including administration, electrocardiography, electroencephalo-graphy, environmental services, food services, GI lab, laboratory, medical records, nursing, occupational therapy, pharmacy, physical therapy, radiology, respiratory therapy, and speech therapy.
