Study Notes
Venous Blood Collection
- The best site for venous blood collection is the median cubital vein, located in the antecubital fossa.
Importance of Venous Blood
- The majority of routine tests are performed on venous blood because it is a more representative sample of the body's overall circulation, providing a more accurate reflection of the body's physiological state.
EDTA (Ethylene Diamine Tetra-Acetate)
- EDTA is an anticoagulant used in blood collection tubes, functioning to prevent blood clotting by chelating calcium ions, thereby allowing for the collection of blood samples for hematology and other diagnostic tests.
Specimen Labeling
- A properly labeled specimen is essential for blood collection to ensure accurate patient identification, prevent specimen misidentification, and maintain the integrity of the testing process.
Test Request Form
- When handling a test request form, it is essential to note carefully the patient's demographic information, test(s) requested, and any special instructions or requirements to ensure accurate and efficient testing.
