Final Answer:
For Hemoglobin and Hematocrit tests, use lavender-colored tubes. For Vancomycin, Phenytoin, and Digoxin, use light green-colored tubes. Follow standard venipuncture procedures for blood collection.
Step-by-step explanation:
Different blood tests require specific tube types to ensure accurate results. Hemoglobin and Hematocrit tests are commonly conducted using lavender-colored tubes, containing the anticoagulant ethylenediaminetetraacetic acid (EDTA). EDTA helps prevent blood clotting, allowing accurate measurements of these parameters.
On the other hand, Vancomycin, Phenytoin, and Digoxin tests are performed using light green-colored tubes, which usually contain the anticoagulant lithium heparin or another suitable anticoagulant. The choice of anticoagulant depends on the specific requirements of the test. These anticoagulants prevent blood clotting and preserve the integrity of the sample for accurate analysis of drug levels.
To collect blood for these tests, a healthcare professional follows standard venipuncture procedures. This involves selecting an appropriate vein, cleaning the site with an alcohol swab, and inserting a needle into the vein to draw the required volume of blood. The collected blood is then gently mixed with the anticoagulant by inverting the tube several times to ensure proper mixing and prevent clot formation.
Adhering to these guidelines is crucial to maintaining the integrity of blood samples, ensuring accurate test results, and providing quality patient care. Healthcare providers must be well-versed in the specific requirements of each test to guarantee the reliability of laboratory analyses.
