CHAPTER III METHODOLOGY RESEARCH ENVIRONMENT The collection of blood specimens (experimental group) was conducted within a 150 meter radius of selected cell towers with a dense population within the province of Nueva Vizcaya, Philippines. The examination of the morphology of the collected specimen was processed at Saint Mary’s University particularly in Medical Technology Laboratory and Center for Natural Sciences Laboratory (S205), and for the Complete Blood Count (CBC) was conducted at Nueva Vizcaya Provincial Hospital (NVPH). SUBJECT OF THE STUDY Respondents were randomly chosen. Control samples were those who reside far from a cell tower and the experimental group were those who reside within the 150 meter radius of a cell tower station. …show more content…

Identify the patient by having the patient verbally state his or her name. 2. Assemble supplies. 3. Reassure the patient. 4. Position the patient. 5. Verify paper work and tube selection. 6. If necessary, to help in locating the vein, ensure that the patient’s hand is closed. 7. Select an appropriate venipuncture site, giving priority to the median cubital vein. 8. Cleanse the venipuncture site with 70% isopropyl alcohol, working concentric circles from the inside to outside. Allow the skin to air-dry. 9. Apply the tourniquet 2 to 4 inches above the selected puncture site for no longer than 1 minute. 10. Inspect the needle and equipment. 11. Perform the venipuncture by anchoring the vein with the thumb 1 to 2 inches below the site and inserting the needle, bevel up, with a 15- to 30-degree angle between the needle and the skin. 12. Put the blood sample collected in an EDTA tube (i.e., lavender stopper) and gently invert the tube 8x. 13. Store the inverted EDTA tube in an icebox (4 deg. Celsius for 6 hrs.) for transportation. Complete Blood Count 1. Get the blood sample collected in an EDTA tube from the ice box. 2. Make sure that the sample is already in room temperature before feeding into the machine. 3. Then, mix the tubes
